Finer than frog's hair, CL. Just following my SBC powered Fords where ever I want to go.

I can't handle it.
The 383 chevy is a stroked motor and it cannot compare to
the 383 Mopar - for it is mighty.
I love the sbc's, particularly the 400, but, I've got a 1973 400 Mopar too, and it has some of the thickest main webbing of any of those MM blocks. When I get the stroker(4.150s x 4.375b) kit for it it's gonna be 500 cubic inches. Let me compare that to the wimpy 454 in standard form. I bet it'll burn 87 octane and any tires you can find.

The 400 is probably the worst small block Chevy ever made

Although both are over square the bore/stroke ratio of the Mopar (1.26) is better in terms of performance than that of the SBC stroker (1.05) for one thing. The longer stroke of the SBC will give it a slight torque advantage at low speeds but will be a detriment at higher engine speeds. The shorter stroke and larger bore of the Mopar has the advantage of lower piston and bearing speeds combined with room for larger valves. The longer stroke of the SBC 383 will cause the rod and piston to travel at higher speeds in comparison to a short stroke Mopar 383. This means the RPM of the SBC must be limited (or special high strength parts must be used) to prevent physical damage to the engine. Those differences alone mean the engines, if built to the same performance standards, will definitely NOT perform identically.
There you go again centerline comparing apples to oranges. A certain mopar 383 had the same bore and stroke as the chevy. I am talking about what you first said about identical engines. You can't seem to follow your own rules.

interesting read!!! i think it's an apples to oranges comparison. --"my pepsi can beat your coke, it has more carbonation for better volumetric effency, my pepsi is faster sipping than your coke--you coke guys are all wet.

seriously, i am a chevy guy, i,ve had several big block 60s chev muscle cars, but was enevetably was confronted with creeping rust (like chevelles common rust below the rear window and in the trunk wells). i switched to corvettes in the 70s, plastic doesn't rust. been a loyal fan ever since.
BUT, having been a mechanic in the 70s and having worked on many big block mopars, i have nothing but respect for them, nice design, great power out of the HiPo models, great strength, chrysler was right up there with the best in the horsepower wars of the 60s, sometimes ahead. remember the 413-426 wedges of the early 60s??? the 383 (and 440) that are the subject of this thread were great engines in there HiPo versions. (even though i have no proof i have read many times the 440 could even beat the 426 hemi in STREET TUNE). about the only thing i see wrong with the mopar engines is they weren't as popular as the GM and ford competetors.

141s posts were hilarious, he was born in 1976 (i was working on mopars before 1976), that means he didn't start driving until the 1990s and his opinions are based on his vast knowledge of driving a couple of dubious cars with unknown engines/equipment/tune/etc.

oldred's long post was so informational and accurate it ought to be in a book somewhere!!!--great post oldred
just my dual centavos.

Oh I see. You want to compare the SBC stroker to a one year only (1959) Mopar engine instead of the one we've been talking about since the beginning of this thread. Next time try NOT to jump in a thread that's been around for a long time and define your own comparisons. Also try READING the posts carefully before you type so you won't stick your foot in your mouth again.

SAME PERFORMANCE LEVEL does not mean exactly alike.

Exactly! Now the Mopar 383 vs. the Chevy 396... that would be closer to apples to apples.

390 horse out of a stock 383 mopar?? i don't think so.. the 440 magnum was rated at 375 horse and the 440 six pack was rated at 390 hp... 383 was more in the area of 335 if i remember correctly....



that said i'll take the 383 mopar every day of the week...

The MOPAR 383 makes 325hp and 425 ft-lbs torque. I have one in my car, and I can sure vouch for the torque, but at the same time it still loves to wind up. I too would prefer the MOPAR any day of the week.

All you chevy boys think that because you went to Schucks and got a set of chrome valve cover's and a performer intake that your 350 is the baddest s*#t on the road. I'll put the 383 (looks restored but not stock) in my '70 Challenger
up against any sbc stock or not!

To make it fair both enignes would either need to use stock ehads or aftermarket heads. Either way the MoPar is going to get you the fastest ETs, wind up quicker and be able to wind tighter, and also probably make more torque at the same time.

These Chevy guys think that nothing can wind up liek a small block Chevy, thats a load of BS. A 383 MoPar can pin a tach as well as anything and still has big block torque. I know of a guy who is putting down over 500 hp with a 383 MoPar, just over 9:1 compression, and get this UNTOUCHED STOCK 906 heads other than flat milling to get the compression up with the terrible pistons hes using. I dont know him personally but his name is Dwayne Porter, he owns a small engine building service, and the car its in runs low 11s.

As for a stock 350 Chevy beating a 340 Six Pack, ha tough luck with that. A 340 Six Pack e body is a 14 flat car (in fact stock tests ran 13.99 by one mag) and NO stock 350 Chevy ever cracked into the low 14s other than the LT1 Vette. The mighty LT1s int he likes of Z28s were good for mid 14s.

Chevy made some great engines, but the 350 isnt one of the greats. Its just a good one that works well and has a big aftermarket and years of experience. The 383 isnt a great either but its a damned good one, but it beats out the 350 stock for stock and against a 383 stroker Chevy if both are prepped similarly even with stock iron heads on the MoPar it will and can be just as great if not better than the Chevy.

hi

whats goin on guys i honestly can put to rest this 383 v.s. 383 stroker argument, i build engines ... well whole cars here in oklahoma, engines are my thing though. i have a 383 stroker chebie and a mopar 383 i built just for this arguement. ill start with the chebie 3.75 stroke 4.030 bore with speed pro powerforged pistons(10.00:1 comp) 4340 h-beam rods dart 210 cc heads 64cc chambers (cast iron) with 2.05 1.60 stainless valves edlebrock torker 2 intake and a demon 850 mech. carb the cams are identical had a machinest make em they are a dual patten 286 .486 intake side, 292 .486 exhaust side( at the valve with 1.5 roller rockers, msd 6al and pro billet distributors on both they are both ballanced and are solid lifter, the only diff is the mopar is 9.85:1 comp and the intake valve on the mopar is 2.08.

the fun part the chebie is in a 78 camaro with a 3500 stall and turbo 350 with spool and 3.55, the mopar is in a 73 charger with a 727 and 3500 stall 3.55
gears both leave on the brake at 3000 rpm and both have 28.0 15 11.5 slicks
drum role please the charger wins by 1/2 to 1 full car legnth 5 out of 5 races 13.70 to a 13.90 average
oh and ps the camaro is 3100 lbs the charger is 3750 lololololololol
