1970 GTX 440 - Classic Mopar Dyno Tested Before & After Rebuild

[@OverlandOne]

I had a 1970 440 in my Plymouth Fury Police Interceptor I bought in 1976. It had the Police Package including the dual point distributor. I rebuilt the motor going .030" over using high compression pistons and a Direct Connection Purple shaft cam. I added a mid rise Wieand aluminum intake manifold, headers and glass packs along with a Holley 650 double pumper carb. I drove that car back and forth from college (1,600 mile round trip) many times and it ran great. It dynoed at a little over 500 H.P. and got 20 mpg on the highway thanks to the cop gears. I pegged the 140 mph certified speedometer more than once on those trips. A Kentucky State trooper once clocked me at 147. (Pretty serious as we had 55 mph national speed limits back then) I loved that car. PS Mine had Petty Blue valve covers from the factory, not orange like this one.

I still have my Dad's old 1973 Dodge Polara California Highway patrol car number matching 440 police interceptor. Very fun car to drive.1st gear does 70mph 2nd gear does 118mph drive I had it to 140mph.

My dad had a 440 GTX once it was trade for a Chevy Panel Van . Sadly he sold it almost immediately as a family man with three young boys he didn't need it , he got about $2500 for it , what a shame in retrospect but it was simply a used car to my Dad with no other value to him. Oh well at least we had it for a few weeks to ride around in great memories and bragging rights to my 12 year old buddies .

Nick..I just want to say a big THANK YOU. I have gotten old and can not get around as well as I used to any more.. But was a good shade tree mechanic form the 50's, 60's and 70's I actually though about making it a career at one time (I eventually became a carpenter more travel ;-) But I miss those days.. I did my last car two years ago it was a 62 t-bird and it was a real struggle for me. So that was the last one.. But I miss it so much.. and like you it was the engines I love to build the most.. This program you run here help me remember with joy those younger years.. The days go by so fast it seem..

Excellent results. I also found it interesting how the before and after results of the manifold vacuum readings at wide open throttle. Before the rebuild it was at neg 1 inch of vacuum, and after the build it was at 1.6 inches of vacuum. Also with the air filter it went up to 2 inches of vacuum. You can see it was definitely breathing better after the rebuild, and would benefit with induction upgrades like Edelbrock Performer, or Performer RPM intake and K+M filter insert.

Great video, my dad had a '71 Chrysler Imperial with a 440, he would let my brother and I drive it all the time in the 1980's. The Imperial probably weighed several hundred more pounds than a GTX or Roadrunner , but it would still get up and move when you open up the 4 barrel carb. I later bought a 1972 Plymouth Satellite police model with a 318 motor and my dad bought a 1981 Cadillac with a 350, We ended up selling the Imperial with 220,000 miles on it for $2500 and the guy that bought it was till driving it years later and it still looked like it was in show room condition.

Nice!!! Thanks for this vid, love those engines. 440 is a scary fast street engine!! Old story, 1985, same friend of mine who was into 318s went to NH to buy a 71 Roadrunner, guy didn't want it anymore and hand painted it w/paint brush, LOL that you would use on a house, black, to keep it from rusting. 500 bucks for the car, body was straight no dents and the 440 (whatever original mileage at the time) was a beast, when he brought back to MA and picked me up in it the next day, the car was an absolute torque monster that pinned me the minute he floored it. Stock 440, 727, 3.55's, Carter AFB. He knew how to pick em fast for cheap. Car ran 13.5's on snow tires at NE Dragway. Treated the car as a beat on throwaway and was trashed the following year. Man, if we only knew what we had back then - now! Peace.

Watching 440s on the dyno never gets old. Back in '75 I bought a '68 Charger R/T (440 with a 727) for a whopping $800. Hey ... it only had 97,000 miles on it. :).

This is a more realistic dyno pull than I am used to seeing here: 1) carb with vacuum secondaries instead of double pumper 2) air cleaner on the engine 3) timing that is livable on the street under all conditions rather than bumping it to get a flash reading 4) Vacuum advance hooked up. All they above are how an engine on the street must live.

Back in the day 1970 a friend of mine wanted to build a Dune Buggy. VWs were pretty rare in the southwest so he decided to go the Corvair route. He went down to the El Paso, TX, Auto Auction where he bought a 1965 Corvair Monza 140hp with a 4 speed. This car started and ran a little bit. I went with him to pick it up. A 1969 Chevelle 350 sbc and 3 on the tree his POV was our flat tow car to take it back to WSMR where we were both Lieutenants in the Army. I only threw in the Chevelle bit for a little eat your heart out. After getting the car back to WSMR, White Sands Missile Range, NM, and the auto craft shop, we dropped the engine and our jaws. The first thing we noticed was that there was a brand new harmonic balancer. When we pulled it off we saw why. The outer part of the balancer, which is connected to the hub by a band of rubber, had separated like Nick’s was about to and ground a groove in the aluminum back plate which carried a lot of oil passages and was cut right through. Next we took off the oil filter adapter which hangs off this plate and has oil passages to and fro from the filter. Someone had short circuited this by drilling a hole between the two passages and packing them with bits of rags. The Corvair was air cooled of course and required a large amount of sheet metal bolted to the engine. None of the nuts and bolts matched. We took the flywheel off and rang it on the floor with a dull thud. Corvair flywheels were multilayered pieces held together with large rivets. If you tap it on a concrete surface, it should ring. Otherwise it’s junk. Finally we started dismantling the engine. Clark worked one bank and I worked the other. After I removed my head, I saw that there was a hole burned through one of the pistons on my side. This engine ran, sort of. One more story. The Corvair had the crank above the cam. The pushrods ran to the heads through tubes underneath the engine. These tubes were a big source of leakage in these cars. So Clark wrote a letter to several aerospace companies on WSMR stationary saying that he was 1Lt Clark B. Blah,blah, blah. I need O-rings to work between a hot air and hot oil environment, blah, blah, blah. I am starting my investigation and will eventually need a run of 10,000 units. Please provide a quote and a sample of a minimum of 24 units. See 2per valve, 2 valves per cylinder, 6 cylinders, ergo 24. The quotes came back at about $10 per unit, and we got his engine built. Clark was a good old boy from SC and knew his stuff. The Dune Buggy never got built.

The 1970 GTX is one of my favorite body styles. I've seen vintage factory Mopar dyno tests from the 1960's for the 375 hp 440's and they were usually around 350 hp to 355 hp with random engines pulled from the assembly line for testing. Mopar limited the valve springs to protect the cast pistons from high RPM and the 1970 440 has the pistons farther down from the deck than the 1968 and 1969 440's. As the valve springs wear, the valves start to stand open and leak a bit more at lower RPM that they do with new valve springs.

pretty sure he meant the vacuum choke pull off/s, likely also electric or intake manifold heat operated. they generally had two vac. pots (often coined dash pots) to slightly pull open the choke upon vacuum increase(engine start) and the second controlled further choke pull-off and vacuum secondaries so it didn't fall flat, backfire or stall when an unskilled person attempted to drive ;) I grew up driving carbureted vehicles, rebuilding carbs. setting distributors, timing, points, dual points or more doesn't scare me the least bit.

A Carter has a single vacuum pot (1 1/4" diameter) for pulling the choke back slightly from full choke position when the engine starts. Holley is the same, one vacuum pot for the choke. The vacuum secondaries on a Holley (2 1/2" diameter) has no association with the choke other than the choke must be fully open to disengage the mechanical interlock that prevents the vacuum secondaries from opening when the choke is not fully open.

Greetings from Michigan,Nick mentioned how much work it takes to put the engine in the dyno room,how about a complete start to finish video of that? Love your channel!

[@NicksGarage]

Interesting idea. Thanks.

Excellent video! I liked the before and after testing. Probably the only engine video like this on KZbin. 👍👍😀

Great Episode!!! The un-restored 440 put out a lot less power than the restored unit... A lot of times, I have noticed that opening-up engines with over 80k. miles and several years of normal usage, they have stuck rings, lifters that are not working properly, loose camshaft(s) timing components, lots of carbon in the intake & exhaust passages, valves / valve seats / valve guides and stem seals that are not sealing properly, worn distributor shaft bushings / primary timing components / inoperative distributor vacuum & centrifugal advancers, and carburetors that are not atomizing the fuel properly because of restricted/clogged jets, air bleeds and leaking float valves, along with various places that allow engine oil , coolant and vacuum to leak... A decent overhaul will greatly help to cure these issues and make them go away... As Nick displayed with this nicely overhauled machine. My guess is, after the new engine parts and re-machined surfaces have become fully seated and broken-in, that engine will produce an additional 20-30 h.p. and another 30-40 ft.-lbs. of torque.

[@michaelmartinez1345]

Just checking in again , a year after first viewing this excellent episode... These Dyno checks reveal so many things about the engines... Very interesting results...

[@solodad001]

I live close to Tulsa, will keep my eyes open. I used to have a '70 RR, 440 4spd....I wish I still had it. Love the show.

[@scowell]

Older carburetors often have problems with the butterfly shaft moving... this causes hard-starting and problems idling, especially when cold. I trust that the carb rebuild addresses this... I'm sure a few ponies were left on the floor due to the old carb in other respects.

[@lautburns4829]

I hope the shaft moves, do you mean the base plate is worn allowing a vacuum leak? Poor mixture and uneven idle speed.

[@scowell]

@@lautburns4829 Yes... my 1970 Dodge motorhome had an original Holley with a throttle shaft that would move about 1/16th inch... impossible to set idle, or idle mixture... if you don't change the air filter, then air and dust is sucked through the gap, widening it... that shaft should be lubricated every so often, and the filter changed. You can drill it out and re-bush it to renew it. If you've ever examined the throat of a carburetor and looked at where the idle jets lie in the bore you can understand the problems. It also had a worn-out distributor, those need occasional lubrication too.

[@garyphilip3382]

Nick , thanks so much for all your great videos ! I never got to see anything like this in 1970! Also it’s nice to see George sometimes from an incar or other stationery camera .

[@davidlj53]

This guy loves his job, very fortunate.

[@johnkufeldt3564]

Excellent tests Nick, thanks for the before and after tests, something I as well as others have lI kelt been interested to see. Cheers from John and Ashly in Calgary. Have a great week at Nicks.

[@terrybartak7811]

I love your real world honesty. With the stock manifolds, intake and carb very impressive. Thank you Nick. You are the real deal.

Hey Nico I just want to tell you a little something I watch the boxing match and it was a Greek fighter tonight he lost the match but he felt like hell and never hit the mat it was a decision match he gave it all I had so much respect for him

That is decent power with your air cleaner on it!! Take care, stay safe ,stay healthy and God bless!!

[@tbamagic]

I had that same engine in my 1969 Century Coronado runabout. Had a double-pumper Holley on it. Ran like a top. Tons of low-end grunt....would plane out with 12 adults.

[@danohstoolbox]

great numbers your getting out of the motor nice work nick

[@NicksGarage]

Thanks 👍

[@woolyhighlander7280]

I see it's an externally balanced engine, meaning cast crank, but maybe it's a lower comp. "smog" motor like a 1974 or 1976, I enjoy watching your channel, thanks Nick.

[@leighhardy9926]

Another great Monday morning.... I like these videos.

[@CoastalAutoReactionCAR]

That tired 440 sounds and runs a lot like our 383 lol Nick is used to fresh engines that he has had his hands on. Test an engine like this is nerve racking for Nick! That noise sounds like the flex plate maybe? Thank you for doing this Nick I can only imagine how stressful this must have been! Cheers

[@imarobot3757]

that 440 had covid low cyl pressure , it was sick

[@CoastalAutoReactionCAR]

@@imarobot3757 It was prob a good runner tbh our 383 is tired and will prob need a 30 over bore lol it has about 197k miles in a truck that worked.

Ooh A before and after video because with this 440 we just have to know How will it behave and how fast will it make the GTX go I'll bet money it won't be slow Another awesome Monday Nick's Garage show
