The Original Mopar Cross Ram Intake Manifold

Before the Max Wedge, Chrysler engineers went all in on the concept of sonic tuned induction systems for high performance passenger cars. The "Long Rams" ran as optional equipment from 1960-64 and remain one of the most enigmatic intakes ever fitted to an American car.

[@UnityMotorSportsGarage]

The RamChargers... Inventors of the Tunnel Ram intake!

[@thegreenerthemeaner]

Ummmmm, no. The box with the hoses on it was used by Chrysler to determine the effect on length and diameter of the port for cylinder filling. It was lazy because of the plenum size. They found that by reducing the plenum and lengthening the tubes, they could achieve a velocity that would push the charge rather than draw it. Tunnel Rams back then were lazy at low RPM but made crazy power in the higher RPM. That concept was taken from Rochester Injection units found on GM cars in 1957; Chevrolet and Pontiac. Similar upper manifolds with the lower cast to the needed engine. To that it is thought that Offenhauser took one and machined a carb mounting on it and closed the side air inlet. All of this just shortly after the release of Fuel injection. Large plenum, short runners what a small block Chevy needed and could do. This was the exact opposite effect Chrysler was looking for. Chrysler even experimented with a long set on one side and shorter on the other, trying to make a flat torque peak. It did not achieve the desired result so the mixed runner idea was forgotten. None the less, it gave them the learning curve needed to make the Max Wedge and Hemi programs lethal when released on the public. Notice nothing like a tunnel ram as we know them, was ever used by Chrysler. They built the old 350/361 for torque, not RPMs. I am curious if the 383 ever got the Sonoramic treatment.

[@UnityMotorSportsGarage]

@@thegreenerthemeaner the "idea" of the Tunnel Ram did come from the RamChargers..of course it was modified through the years to achieve the desired results that people were seeking. Tunnel Rams when "properly sized" to the engine it is feeding will deliver more torque than any other manifold design...

[@LunarOutlawsGarage]

You got to love the ram air era. It is what made the GS stick out to me. I was over at my grandfathers house and The tarp that was covering the neighbor’s car blew off. it had been sitting for 25 years at that point and that hood in all of its glory was showing. It took 13 years to get it after that. But I have and It still impressed me to this day.

I love my old Honda, if I had a bit higher budget for parts, I would also be rebuilding an old Chevy truck. I worked on modern vehicles for a little while as a lube tech at a VW dealership...... never again. The Germans do stupid crap, AND charge way too much for it. The American vehicles did other stupid crap, but it wasn't insane expensive to fix.....Toyota is a pain in the ass to work on, but they tend to be reliable, and Honda tends to (in my experience) still be pretty easy to work on for the most part and reliable. I had a Nissan Rogue break down just after it was taken off my lift, because of a recall that was never taken care of...this vehicle was being inspected for sale on the lot as a used vehicle.....and it cost the dealership money because no one had bothered to check if it was up to date on its recalls...I dealt with so many broken vehicles that were only a few years old, did not matter if they had been taken care of or not, but I saw far more issues than is acceptable, more so for the cost of modern vehicles. Yes, have been crap cars through out car history, but by this point.... they should know better. But, welcome to a world where its all about buying the newest thing with the most gadgets.

A friend of mine's Dad had to put his car in the shop.....so we ran it to the Chrysler garage and they gave us a loaner car to have until it was fixed. My buddy and I went to bring the car home to his Dad and, lo and behold, it had a Ram-Inducted 413. Needless to say, we took all afternoon to get it to his Dad's place. Talk about a hoot! When the dealership got the 413 back the rear tires were, uhhh, much reduced! LOL Those AFB's were sitting right in the back corners of the engine bay and just looking at them got your blood pumping.....those were the days. Thanks for the memories, Tony.

[@kencohagen4967]

I found an article on these manifolds and it gave all the theory behind them. Now here's the kind of cool part. When I was working in the shop, pulling parts for customer custom builds and was sorting through our gasket section in the warehouse and I found an open box AMC V8 intake gasket. A little ways down the line I found an open box Big Block Mopar intake gasket. Both were steel or tin type gaskets and when I pulled them out of the box to make sure that weren't bent or rusted, the intake ports looked very similar. So I put one on top of the other and the ports lined up perfectly, but the width, one side from the right to left banks went the same. And the Mopar had an open lifter valley which took its own cover. The intake manifold in stock covered that area while the AMC went under the manifold. But the distance from the front to the back of the ports was exactly the same. So, when I found this article on the Mopar Rams there was a section on AMC guys using them on their engines with slight modification. The ram intakes were tuned for peak torque to arrive at 2800 rpm or slightly higher on the shorter version. Side note, there are three different versions of the ram intake. The first is a long ram tuned to a lower RPM, a long ram with Exhaust Heat to warm the air fuel charge for winter operation, and a short ram for higher rpm. These are some of the coolest manifolds I've ever seen, and they were making replicas back when I found the article.

Tony, I was an 18 yo apprentice in 1968, the garage sent me to Lake ave. Auto parts (Rochester) one afternoon. There on the wooden floor of the counter area were 6 sets of these intakes, complete! I knew exactly what they were, thinking "Oh cool!" But they were already, in my mind, outdated. Yeah, I wonder what happened to them.....LOL! Great memories.

[@ericheine2414]

"Spaghetti Cross Ram Air Intake" When you lifted the hood on a 60s letter car and you saw this your mind was blown. There were these support rods that ran from the bottom of the intake manifolds to the top of the exhaust manifolds. The throttle linkage traveled between the two carburetors to a pivot plate. You wanted one. You wanted one so bad. You were lucky if you got to look at one. They belonged to your rich friends uptight father who wouldn't let you anywhere near his car. This setup was primitive space age technology from the dark ages of the future. There did you get a good look at it? Good now get lost. Every now and then you would find half of one broken in a wrecking yard, or the remains of an already scavenged vehicle. Rarer than hen's teeth. Collectors who collect this shit. Rarest of all was one with a 4-speed. And they would all stand around talking about "stump pulling power" Compared to this you didn't have shit. 130 miles per hour all day long. No sweat. Let the cop follow. All the way across Wyoming headed towards Jackson Hole, with your skis running between the four bucket seats.. The car had ashtrays, so you could smoke between drinks. Montana had no speed limits. Do you know how fast I clocked you? Over 50. I spend up to 70 while you were standing on the brakes. That would be over 50

[@brownwrench]

Change spark plugs through the wheel well

[@yourreunioncommittee8220]

Support rods?!?! Do you mean the exhaust tubes between the intake and exhaust to provide heat for fuel vaporization?

[@LunarOutlawsGarage]

I really like those cross plane intakes. I can only imagine the torque pump they created

[@LunarOutlawsGarage]

I am hoping to put the Edelbrock 71413 cross ram intake b/c of this era of true engineering. They reached the limit of what could be done. So they made another way to skin the cat..... just like the SR71 black bird they did it with out computers. Sometime the art of engineering is lost in a computer

[@LunarOutlawsGarage]

Lassi Kinnunen lol obviously they didn’t hate technology they were on the cutting edge of technology. My point being is just like Math nowadays it’s hard to do things without a calculator because we are reliant on them. When the SR 71 was built they didn’t have computers to do the math for them. In 1966 when the SR71 was built computers were highly specialized pieces of equipment. Five years earlier in 1961 we sent The first Apollo rocket into space. The Apollo project push the boundaries of technology and if you ever get a second you have to look at the original Apollo flight programming computer it’s impressive. It may have less computing power than a phone from 10 years ago however it’s so dedicated to what it does that a modern iPhone couldn’t fly the Apollo rocket. It was essentially a computer that was the size of a small building but with the invention of integrated circuits they brought it down to the size of the picnic table. There’s a KZbin video of them actually restoring One that failed to launch because of a sort in a potted circuit. After they repaired it they managed to initialize it and hook it up to a modern computer and had the original flight plan on it and that’s incredibly amazing and speaks to the quality of the computer they built. lol sorry got off on a tangent I do that but yes in short they didn’t have computers and said the late 60s however they were not the kind of computers you’re thinking it wasn’t until there was a huge revolution in the design of computers mostly driven by a few very competitive computer designers and businessman. During the ram air era the engineers really did just do a lot of grunt work when it came to designing. Now where where I was going with all that lol. I think there is some of the creativity and imagination lost using computers in engineering today. Not saying that the things that are being built are built better to just less creativity in solving problems. I think it’s mostly due to complacency not say laziness. Anyways that’s how I feel About it. And if you just read all of that I would really love to know your opinion on it 🤘

[@LunarOutlawsGarage]

Lassi Kinnunen in fact I watched a documentary recently where they re-designed the SR 71 blackbird on A computer using auto desk inventor and they could not make any improvements the design was flawless.

[@raoulcruz4404]

Engineering means keeping your mind engaged. A hydrologist told me about his first big job. He had a pencil and paper and a mechanical adding machine. When there was a discrepancy in data it was readily apparent because his mind was involved in all the calculations. He retired right as the super computers came about. Two young engineers ran the computer, just feeding it data. Well, GIGO. There is a very large lake dam here that is 2 feet lower than intended because of that computer.

[@MessalineApghar]

@Lassi Kinnunen the story kelly tells is that all the engineering and calculations were done by hand on all the variations of the blackbird until they revisited it in the 90s or 2000s and the computer analysis said that it was literally as optimal as possable and had no further design& engineering-change suggestions

Awesome video in high school my senior year I rebuilt a 300J Chrysler with a I think it was a 426 wedge cross ram or a 413 can’t remember but that was a neat car . Two door bucket seats , rap around dash and a push button automatic. Then in college at Mt Hood Community College we had a awesome s auto program with a complete machine shop. And had a auto club which was a 501 , 3c nonprofit and a bunch of instructors that liked to build race cars. The first car built from basically junk parts was a 62 corvette with a 327 bored .030 over. Well our main competitor was a guy from Woodburn, Oregon that had the nickname the Mad Russian because he did some crazy stuff. Well his car was a 64 Belvedere with a 426 wedge duel 4’s and the short cross ram and a push button torque flight and we ran in super stock class. We could only run the 327 4 barrel carb. He used to kick our ass. Well over the years we went all out roller cam .600 lift triple springs , stud girdles and some illegal heads at none point match meets. Our engine we’d come off the line at 10,000 rpm then shift at 8,000 rpm but he would always beat us by 2 one hundredths. Many years later I ran into him and told him who I was and the car so I said we were running illegal heads. He said he figured we were but he never challenged us because he always won. All you had to do is remove the carb and look down the runners to see we were running 202 ported and polished heads, fun times. P S the name of the corvette we rams was HomeWork

[@raoulcruz4404]

One of my favorite cars to watch drag race was a stock category 63 Belvedere station wagon with a Max Wedge engine. The owner said his parents bought the car new. He remembers as a kid, mom driving it around town shopping and such. I saw it run in the early ‘80’s. If I recall correctly it ran 12.6 in the quarter mile. Headers and slicks the only alteration.

[@edwardmartin3069]

I actually saw one of these engines back in the later 1960s. While in college, our neighbor across the alley was a car nut, as was his brother. The brother and a group of his buddies ran a "hobby-stock" dirt track race car at the local track. The year I met them, the track totally changed the rules for their class of race cars. The old race car was a '35 Dodge coupe with a Chrysler 354 C.I. hemi with a class limiting 2-barrel carburetor. The new car would be a fiberglass bodied car with an in-line 6 cylinder limited to 250 C.I. still using a 2-barrel. Anyway, one of the guys took the '36 Dodge coupe and put in a 413 engine with the cross-ram intakes hooked to a 3-speed torque flite transmission. I got to ride in the car on one of the test drives and it was AWESOME. The total weight was probably less that half the weight of the original Chrysler and it would fly.. The sound of those two 4-barrel carbs kicking in when the RPM came up was totally unforgettable... The visual impact of that engine just cannot be imagined. You have to see one to actually feel the impact...

[@56clipperable]

I had the opportunity to work on a 1960 Chrysler 300f with I believe was the 413 with the cross ram manifold. It was wild to look at and drive. Also My boss used to race modified's in the mid 60s and ran 426 max wedges with stage 3 heads and the dual carb manifolds. He still had all that stuff in a room in the back of the shop when I started at this Chrysler dealership back in 1996 but sold it all around 2007 or so. Basically gave it away for 6500, which is what I thought then. It was 5 complete engines and 2 blocks ( all stressed out from racing tho) and a whole bunch of other parts.

He showed me where the factory had cut a good size hole in the inner fender. He said he would jack the car up and take the front wheels off and reach up through their with a long extension and a wobbler with the spark plug socket on it. There was a rubber flap covering the hole so that water and mud wouldn't splash through the hole. My Dad told me about being on the highway in the mid 60's and coming up on a Texas Hwy Patrol car on the side of the road right as a speeder passed it. He said you could see the left fender just torque up as he got on it to catch the speeder. Dad was impressed.

The aluminum heads have every mod developed for the cast heads included in the price of them and will outflow the best iron heads right out of the box and weigh 45% less. Also 'smog' heads are better than 906 heads. Non other than Steve Dulcich showed that in a series of 3 or 4 Hot Rod magazine articles. If you want the links let me know - they're still up. If he wanted to do it on the cheap just bolt on a set of 70s oem heads with new springs. The only issue I can see is the late heads are all 6 bolt rocker cover rather than 4 bolt and if there's an asthetic issue he'd be using the early heads anyhow. Sometimes the performance is not the issue.

[@caseycuda854]

@@ThePaulv12 oh it's always a question of price. If money isn't a problem and in the "land of Mopar" that is a trick. The old cast iron wont beat new aluminum and for the price I get it, plus the bonus of less weight. But if your like me 906s are cheap and I ain't scared to grind on one to clean it up. But I wont lie and tell you new isn't better. It really just comes down to what your looking for and what you can afford.

[@ThePaulv12]

@@caseycuda854 Just use the late 234 onwards heads if you can get your hands on them. Forget 906s. Sure if you have 906s use them but after reading those articles I will never ever use a 906 if I don't have to.

I didn’t know about that information on the cross ram ,Great Video !!!

[@edwardmarculewicz5140]

Just incredible. Love the videos!

[@johnhodgson5313]

Well done! It was interesting to note how much that knowledge continued to be used by Chrysler, even today. When I had the first version of the 3.5L it had the crossram from the throttle bodies to the heads and the exhaust manifolds looked like shrunken and amputated, by one cylinder, manifolds from a street hemi. Then the later 3.5's were triple tuned. With variable valve timing it is a little harder for me to see the manifold tuning on my 3.6L but the Hemi still does.

[@andyZ3500s]

I like the way you put things in perspective. An good example in this video was that the ram Induction system came out just a couple of years after the national highway system was started. Like you said if you were cruising down a two lane freeway in your 61 300 and you needed to pass the intake was designed to give the power where it was needed.

[@francfurian8215]

Hey Uncle Tony that's why I love MOPAR as well. Their engineers introduced many of the ideas to the automotive & the racing world. Like you said they were well ahead of the curve. By the way I think you would've fit in very well with those guys. Cheers

[@mikeyfourbarrel8473]

Science! Very cool stuff, Uncle Tony. I learned something today.

[@andrewmaxfield6658]

What you're talking about is the same idea as two stroke engines in that the use "tuned headers". The idea is there's a sonic pressure wave from the exhaust and if you time it right, the exhaust pulse pushes escaping combustible gasses back into the combustion chamber. Just look at the lumberjack competitions and you'll see huge tuned pipes coming out of them. For that same reason it's unwise to run a stock engine with open exhaust or even headers without doing extra tuning. As a side note, I ran a cross ram on a big block Chevy. Completely open plenum with 660 center squirters. Just didn't work. Thanks for listening Tony.

[@michaelmartinez1345]

Great episode!!! I have the 30" runner length setups that will be put into an early 70's truck on a 440... The trucks that are towing heavy trailers can really use the torque increase of these... I will first use 2-ea. 390-cfm 2-bbl. Carbs and see how that works... The cam will be one of the mild grinds.... This is the kind of engineering that Chrysler was famous for back in the 50's & 60's...

[@michaelmartinez1345]

That was a great presentation Tony!!! Good job at explaining the differences between the various intake runner lengths... BTW, the engineers who were experimenting on the first gen Hemi's as you had in that photo, called themselves the 'Ram Chargers' and they really developed great ideas in the automotive industry...

[@davidboyden9099]

I had 2 Ford Taurus SHO's. They had a flapper valve that only allowed the long runners to operate until 4000 rpm. At above that it allows the short large diameter runners to operate. The acceleration was fantastic.

Chevy did this with their Z28 Camaros, actually i think it was a dealer installed option, a cross ram intake with frikkin two 750 cfm Holleys on their 302 for S.C.C.A. races, made that car a bitch to drive in traffic but went like hell on the open road. Looks cool as hell too.

Smokey Yunic designed that cross - ram intake for Chevrolet.

[@werewally3156]

@@Motor-City-Mike Yeah thats right! Ya know, speaking of Smokey Yunic, my old man told me that Yunic once said that if he could do it all over again, he'd have done it with Mopar. Even being a Chevy educated kid, i kinda wish he'd had.

[@Motor-City-Mike]

@@werewally3156 Yeah, that whole deal was a little weird! He contracted with Ford as well as G.M., and per his autobiography G.M. treated him like crap, and Ford payed well and supplied some impressing perks, cars, travel on company jets and so on..... I'd have liked to see him stick with Ford, but Chrysler would have been just as good! I'm a Ford guy first but Chrysler is only second by a hair. Getting back to that intake, a childhood friend's older brother had one on a '69 Z28, and it was just as you say - in normal driving the car was a DOG but spin the motor up and the car flew! I think Chrysler wasn't too interested in contracting him, Chrysler always had fine engineering - they just couldn't build at the level of their engineering. Chrysler fought with quality control issues more than anything.

[@Motor-City-Mike]

@CC Ryder According to his autobiography he started before the '60s! He also claimed he "discovered" nitrous from his dentist, but he was a bomber pilot in WWII and the Germans used nitrous in their warbirds at high altitudes to supplement the lack of oxygen for power. He was a story teller, so sometimes I even question his own statements, lol!
