What Happens If You Just Add A Stroker Kit To A Stock Mopar Magnum? - Engine Power S9, E3

We show what happens when our 360 Magnum engine gets fifty extra cubic inches from a forged stroker kit.
In this unconventional build, we focus on enhancing the 360 Magnum's performance by adding a stroker kit, increasing the stroke by an impressive 420 thousandths, taking it up to 410 cubic inches. Watch as we run it on the dyno for baseline numbers, tear it apart, install the kit and then reassemble with all the stock components from cams, cylinder heads, to intake manifolds. Once reassembled, it's back to the dyno where we examine the effects of the added stroke on power across the RPM range.

Stock Magnums were rev limited to 5250RPM. They ran into valve float after that. Stock heads: Michigan heads, 195-205CFM. Mexican 5.9L heads: 215CFM. Make sure you have Mexican heads, better parting lines, and truer to design ports. Wake that engine up with a REALLY good porting and polish with 2.02 intake valves (Steve Sanchez at Total Flow in Troy, MI). Get a better cam, single piece pushrods, and try a set of Crower S.S. 1.7 ratio full roller rockers. My Magnum? No stroker, .030" over makes 395HP and moves my Indy Ram (4750lbs) through the quarter in 13.87s at 102mph. Daily driven, starts every day, AND gets better fuel economy than stock.

"𝘛𝘩𝘦𝘴𝘦 𝘰𝘯𝘭𝘺 𝘮𝘢𝘬𝘦 240'𝘴 𝘴𝘵𝘰𝘤𝘬"... The Magnum engines were rated in SAE 𝑵𝑬𝑻 HP, tested with a full exhaust(from factory manifold to tailpipe) and induction(including the filter/filter housing) as it would be installed in a vehicle. SAE NET also requires all the accessories being driven. The pull you did with long tube headers, no driven accessories and an electric water pump gives you an SAE 𝙂𝙍𝙊𝙎𝙎 HP rating. It's the same reason the 426 'Street Hemi' appeared to lose 75hp from 1969 to 1972 despite the engines being identical.

Do a cam swap and on the stock heads it will make another 50 horsepower or more. What more could you want? Not everyone has 10 grand to throw at an engine.

[@joefreeman9733]

Well not being critical but it is about what one would generally expect to see happen. The small block Chrysler has a long rod anyhow so the stroke to rod ratio remains OK without too much angularity.the up of 50 cu inches is all due to stroke so of course torque curve starts earlier is flatter and appreciably higher. Back in 2000 I built a 360 with Edelbrock alum heads and CR. 10 to 1.that engine generated 414 hp and 440 ft lbs of torque with a pretty hot hydraulic flat tappet cam and 2 step headers running an Edelbrock dual plane and a 3310 Holley. Increase the cubes 50 ci. 50 more ft lbs of torque. On a typical move from a 350 Chev to a 383 with a 6 inch rod watch your torque jump from around 405 to 460 ft lbs even more dramatic 33 more cubes and around 55 ft lbs of torque increase. Not surprisingly the hp didn't do too much because the heads AND the cam are too small for the cubes.the increase in carb size and the result shows what we already knew or could have guessed. The CR of course at 10.75 with the iron heads means you re not going to be using 91 octane pump gas as I am able to do with my 10 to 1 alum head motor. About 4 years ago I screwed together a 408 stroker 360 using the as cast Edelbrock heads a full roller hydraulic valve train 1 step headers and an Indy single plane manifold . CR was 10 .1 to 1. That engine dynoed at 495 ft lbs of torque but 502 hp at 5800 rpm. And yes I went to Carillo rods in that engine. I used a single plane to KILL some torque since the engine was going in a 65 Dart a relatively light car running 3.9 gears. I don't jerk around with net or gross hp When the engine goes on the dyno I'm running belts and accessories as it's going to be in the car if humanly possible the same headers. I generally figure around 65 hp for drive train loss and it's usually pretty close when the car goes on the chassis dyno. It's a nice short block. I'd probably have Hughes or someone similar CNC port a set of Edelbrocks go to a Harland Sharp roller rocker and stand setup put better than stock rods in the engine and keep it just under 6000 with an appropriately sized hydraulic roller cam. It would also be interesting to use a FAST EFi system for more precise fuel monitoring and fuel air ratio across the band than is possible with a carb. Had the builders gone with a lower compres s ion setup in my opinion it would have made an excellent motor for a 1500 Dodge Ram to haul a one car trailer and car particularly with EFI had the engine been running around 9.75 with the iron heads. As it is I'm not sure what you d use the engine for.

[@steveshoemaker6347]

Awesome👀....Thanks guy's 👍

[@topenddean]

305hp and 414 Lb. Ft. for a basically stock 360 is pretty good. And with just the stroker kit swap, 334hp and 490 Lb. Ft. is very impressive. And then they top themselves with the 950 on it, it made 339hp and 498 Lb. Ft. That's insane for essentially a stock small block. BUT, they are running the engine with absolutely NO parasitic loss from accessories. There isn't a single thing pulling off the crank, they don't even have a belt on the crank at all! These are gross horsepower/torque numbers, not what the factory uses. Factory numbers are SAE Net, that is with all accessories, water pump, fan, alternator, power steering pump, and the air conditioning compressor. So don't be fooled by the numbers here. They are good, but not what you will see in the vehicle with all the accessories pulling off the front of the crank.

And we don't know the compression heights of the pistons and whether the new ones were also higher up in the bores as well...

I figured it must make 350-400hp and at least 500TQ, if stock iron Magnum heads and a cam that small did this on a 410ci, I must have been correct, certainly with more cam, maybe a tiny bit of head porting and /or bigger intake valves, a highrise air gap single plane intake and either an 850cfm carb or Holley Sniper it would be around 500hp+ and 475-525tq. This was very encouraging, I could tell the truck is strong, if you dump the clutch in 2nd it rolls white smoke off a 255/85 16 tire that weighs 80lbs on a steel wheel with an open 3.55 diff and keeps burning out violently after the bang shift to 3nd for 200-300feet at 85mph then finally hooks up in 4th around 100mph.

Now if they want to put a cam in it, they have remove all the front stuff, balancer, cover, timing chain, etc. Most everyone would do a cam/stroker kit (extra $375), and then do heads later, that's what makes sense. The way they did it was just a waste of.a stroker kit. But I'm glad they did a before and after dyno run. Everyone remember, the Hp and Tq was Gross, no accessories, subtract ~40hp for water pump, alternator, power steering (A/C), and another 15hp if you're running a clutch ran. Factory 360 magnum was 250hp NET, so with headers, that right where this engine was at.

TAKE MY MONEY!!! - great vid guys

[@_..-.._..-.._]

The 408’s are internally balanced, so you’ll need a non-weighted 318 flex plate or flywheel if you’re working with a 360 setup. The same stroker on the 5.2 318 will make 390ci and you can use the stock flex plate or flywheel.

[@699hazard]

That would sound amazing with a mild cam and an awesome exhaust system

Cheers guys

[@cameronmackenzie4410]

Love to see what a set of ported brodix b1ba's and matching solid roller cam would do here.

[@94XJ]

At first I was really impressed by the stock numbers but then when it was shown to be a fresh reman bored .040 over (which would make it 368 cubic inches) combined with it having dyno headers and the best flowing intake it could possibly see *and* didn't have ANY accessory load, it made more sense. Absolute best case scenario for engine numbers!

[@that_sicksix1719]

Yeah I noticed the same things... Would love to see the same comparison on a junk yard fresh engine with stock manifolds, intake, and distributor... Would be alot more of a true real world test

[@frigglebiscuit7484]

.454 lift cam with .192 duration, and it being retarded 4 degrees...yea, im impressed.

[@frigglebiscuit7484]

@@that_sicksix1719 i saw a vid of a guy dynoing a stock 5.9 as it came out of the truck. it was like 285hp. underrated as hell from dodge, just like the 5.2 in my 93 d150. it runs way too hard at 275k for a 230hp motor.

[@BuzzLOLOL]

@@frigglebiscuit7484 - Dodge just giving the netHP rating as installed in vehicle...

[@BuzzLOLOL]

Just the pre-1971 gross HP numbers... The new numbers seemed way too high... until it dawned on me that the extra cubes cranked up the compression ratio !!! And we don't know the compression heights of the pistons and whether the new ones were also higher up in the bores as well... If the compression ratio had been the same, the new HP numbers would have barely increased at all, maybe 2 - 10 numbers higher... but torque up by around 50 - 60...

[@ralphvalkenhoff2887]

As a Mopar fan myself with a la 360, I’m dying to get a stroker kit. The sound is indeed music like no other and with the torque that thing pumps out, oh man. Woohoo

[@victorjohnson7512]

This high torque low RPM engine would be great in a 4x4 vehicle. Maybe also just add a higher lift cam without getting to radical.

[@1982MCI]

Was just thinking the same thing Victor! It would be perfect in my Jeep Grand Wagoneer that has the AMC 360 in it now that needs to be rebuilt or swapped. It should also bolt right up to the 727 transmission already in it. I need to research this more

[@starbattles1]

too radical. LOL. That cam is radically bad. 192 and 198. lift. For perspective stock 351 cam like mine is 460 lift. My upgrade is 560 and still considered conservative. 192/192 is gawd awefully small. Like WTF small. Who made that crackpot decision at dodge? THAT is why the HP never gets above torque.

[@johnrichardson4327]

This would make a great engine in a pickup truck. I’ve thought about doing something similar to my 95 f-350 with a 5.8 Windsor.

[@CzechSixTv]

If I can't find the 7.3 IDI E350 I want, that's the route I'll most likely go as well. Stroke a 5.8 to 408ci with an 'RV' cam to produce gobs of low end torque. More bottom end torque means you need less gear out back for a given tire size and the converter can stay locked in 4th gear longer, resulting in better mileage than stock.

[@maxwedgedickdasterdly5586]

You guys should do something about the MAX WEDGES ! They were setting 1/4 mile records in 1962. They were the first cars to run 12s and 11s in the 1/4 mile ! In my mined they were the first real muscle cars. I have a factory built 1963 426 MW Savoy. It didnt have a heater , back seat or a radio. And the battery was in the trunk. They were built for one thing kicking everybodys ass at the drag strip. And they did ! LOL

[@MidnightOilsRestoration]

if only more were available. Being made for only 3years makes for very few around and big dollars when they are! One thing you are absolutely right about though....they are badass! Badder than Hemi's in street form.

It was nice to see how this stroker did without changing anything else from stock... Except your intake manifold and carburetor. did the stock even have an 800 carb?

[@Ozarkprepper643]

Stock cylinder heads? Nice numbers! I'm definitely going to stroke the tired old 360 in the 80 1 ton Club cab. Unleash the Power of the truck was meant to do. Pull!

[@demonic477]

take that same 360 bore it 40 over add a high flowing set of aftermarket heads and a single plane intake crank the compression up to 14 to 1 and feed it 120 octane fuel with a good drag spec cam it will really wake up and make power numbers like a big block . I know first hand these are the same build specs my late 70's 360 I raced had it would lift the front end off my dart on a hard pack dirt road and carry it 60 yards before coming down . it was an insane build that I wish I still had you got to love Mopar's

[@HEMIdouglas]

Dodge nut; The suggestions | might make are improving air flow. Checking that intake manifold matches heads and polish. Check exhaust pipe for smooth air flow. Check to see whether long or shorter headers changes when the RPM power peak occurs.( old school )

[@jwright8414]

Great video. Hope you decide to add a much bigger cam and trick flow Heads. Really make it sing.

[@mikef-gi2dg]

I like the stair step build method. Build from the inside out. With a highway gear, and just a little bit of converter, this could be a fun street/highway ride, and a good tire smoker. You can do cam and heads when you are able.

[@BuzzLOLOL]

Wouldn't need bigger converter with that stock cam...

[@erikturner5073]

Kammer&Kammer had a Dakota r/t 5 speed test mule that they were given to try to break the only problem they had was with erratic valve train at high rpm with a rocker arm and beehive valve spring upgrade and a 410 rear gear and some slicks they got the truck to run low 11's consistently without breaking with everything else stockincluding the camshaft back in 1998

[@dbc105]

The stock numbers seem to be common place, Holdener got almost the same numbers on a stock 5.9 with headers and the kegger. He late installed and intake, carb & cam then got 417lbs ft and 349hp and lost nothing anywhere. Good engines,

[@SGTJDerek]

I remember something my Ex-Father-in-Law said damn near 30 years ago. "If you can't make 400hp with stock parts, you don't need to be building engines." He had a 350 in his old car that put down 310hp and 425lbs. Built in the early '80's to pull campers. 2 spd power glide with the original 283 2 barrel carb. 2.73 rear-end from a '57 Pontiac Safari. Loaded down with tools, he drove from Winston-Salam to Jersey for work and got 20+ mpg. I asked him once why he never swapped in a 350TH. He said it wouldn't hit 3rd until 95 even taking it easy.

[@BuzzLOLOL]

Actually a 2 speed PowerGlide is just a TH 350 without a 1st gear... Torque converter was supposed to replace a real 1st gear...
