OK nomex underware firmly in place, here goes! So call me dumb but whats a 383 stroker and how does it compare to a 383 Chrysler engine? Is it technically the same displacement? I had a 383 in my 69 Roadrunner and LOVED that engine.

Regards
Mark

The difference is in how the 383 cubic inches is obtained. I'm not sure on the specs, but maybe one has a smaller bore but longer stroke. They are both 383, but the bore stroke difference of each will determine, roughly, where the max torque will be. The other factor would be weight, head design, etc. A 383 does not equal a 383. <img src="graemlins/pimp.gif" border="0" alt="[pimp]" />

a chev 383 stroker is a 350 with a 400 crank.these motors are expensive to have them bored properly and cut away around the rods, etc. they run about 2-3 grand just for the machining.but they are incredible power makers. my cousin built one,it has about 500 h.p. but he spared no expense.make sure your machinist is not feint at heart, cause they are trickey and really take an expert. mike

if ya have the shop turn down an actual 400 crank then yes its expensive.. but aftermarket cranks are out that don't need any additional machining to go into a 350 block.(for just the crank i mean.. you might still have to notch the cyl skirts?? )

383 Chevy vs. 383 Mopar

Well here's one for you. The 383 Chrysler engine came in 2 forms. In 1959-60-61 the Chrysler 383 was a RB (raised block) engine with the deck height of the 426 wedge and later 440. (You could actually think of it as a small bore 440) It came equipped with the dual quad long-cross-ram manifolds (where the carbs were out by the fenders) or single 4 bbl. It was a small bore 4.030, longer stroke 3.75 engine, coincidentally the same bore and stroke as the 383 Chevy stroker. Then Chrysler made a change and the 383 became a the low deck height "B" engine with a much larger bore 4.250, and a much shorter stroke 3.375. Then in 68 they made the 383 Magnum with a better top end, e.g. Roadrunner. Later this B engine evolved into the even bigger bore 400 cid.

The 383 Chrysler is IMHO in every way superior to the Chevy stroker engine. It was nearly indestructible, came in a variety of combinations and was a real work horse. (2 bbl., 4 bbl., HP 4 bbl., Long Cross Ram dual 4 bbl,, Short
Cross Ram dual 4 bbl, and the venerable Inline dual 4 bbl.) These were all factory available and you could drive one right off the lot, with the exception of the Short Cross Ram which was an over the counter parts option.

If you wanted to do the same thing to a 383 (stroke it) all you would have to do is slip in a 440 crank and you have a low deck 426 wedge that will really rev. This is a great but not so popular combination. It's just as easy to slip a 440 crank in a Chrysler 400 big block where you will have the same reving capability but 451 cubes.

Parts for these engines aren't hard to find although they are a little more expensive than a SBC. A high hp big block Chrysler engine can be built without spending a dime more than it would cost to get the same hp out of a BBC. The fact that Chevys are more popular than their Chrysler counter parts is just because there are more followers in this world than leaders.

Yeah and it will be a very cold day in you-know-where, when ANY 383 Chrysler rules the roost over a crisp and equally-built 383 Chevy. Funny thing is, I know it as well as YOU do!!! I just live in the REAL world -not a fantasy world mopar fans do.

Ask ANYONE who lived life in 1966-1972................Chrysler products were nothing but big, understeering slushboxes that handled for crap and rusted like a cheap tin can. Hmmmmmmmm ......... come to think of it, they STILL do!!!!

Now you all can go on TRYING to come up with some lbogus story about a Mopar dude that pulled up to the line at your nearby strip..... stepped on the gas and brought the tach up to 11 grand and side-stepped the clutch pedal on his Mopar. - right??

WRONG! It was the bowtie brigade that made that bold move and it always will be!!!

Remember - it wasn't General motors that your govenment bailed out. It was the Chrysler Corporation. Success stories don't need financial assistance!!!!!!

Chryslers are garbage. Chevys rule. Watch Pinks and you'll see!!!!

I suppose that's why Mopars collected most of the stock and super stock titles during this time period. I also suppose that's why virtually ALL competitive funny cars and top fuel dragsters have been running HEMIS since the early 60's.

Get real and come out of that fog you've been living in. Between 62 and 72 there was only one production GM car that could even come close to keeping pace with a Hemi and that was the 66-67 427 Vette. If one of those was in perfect tune it might be able to take a hemi, but that was a rare occasion, I know........I was there and owned both a 66 427 4 speed Vette and a 69 RoadRunner and trust me, on most occasions the RoadRunner was faster.

My Bro had a 440 and my cuz had a 383 in there Chargers and Ive been in lots of 383 stroker motors and equally built the chrysler will kill the stroker motor. And I have a SBC in my ryde. But lets be real here. HG

well the 383 chevy is a chevy the 383 chrysler is a bunch a noise.
HORSE-HOCKEY!

Given the two engines in question....... if each had the same compression ratio, same carburation, same exhaust and ignition, in other words if they were built to the same relative performance level, the Chrysler would out perform the Chevy in every category except max RPM. Then again, when you have the amount of torque advantage the Chrysler 383 has over the Chevy 383 stroker, you don't need that extra 500 rpm.

campare the weight of each car body chevy to chrysler there is the advantage i used have a junkyard and when i went out of business chrysler products were the heaviest of all at the scrap yard. but to what you were saying , same compression ratio, same carburation, same exhaust and ignition. compare the weight of each engine the power to weight ratio. besides i dont think it would ive seen stock 350s smoke 340 6 packs and it was stock also all i heard was a bunch racket.

the mopar fans are riding on richard petty's legacy with the superbird hemi. but he didnt race the same guys every week like they do now.and chevrolet dropped out in 1964. smokey yunick built a 427 big block that never was passed under green flag conditions but crashed out in the race. there after chevrolet dropped out.

Why not rpm? A 3.38" stroke would certainly be able to spin higher than a 3.75" stroke. My EA3.2 program sees the Chrysler as the clear winner in every aspect.
I owned a 383/4-speed Roadrunner that I bought new in 1968 and it was a very fast car. I went to the DeVry Institute in Phoenix and in 1975 we were challenged to a school team drag race by Arizona Automotive Institute. My little 383 Mopar ran a 12.08 and was almost a full second faster than any other car there, including some big block Mopars and Fords.

i have lived 1976 to 2006 and i know MOPAR IS DEAD ! and if not there an easy kill.

no dis respect to you on that. but more stroke means more torque. besides im talkin about these cars on the road where everything is true.as far as drag racing thats all in gear ratio, reaction time the car with the most power dont neccesarily win.
