Neveri don't know why everyone is talking about stock numbers though... who here keeps their car stock?

Yet 383 cars smoked 325/350/360hp chevelles regularly. We won't talk about the L78s (real big blocks, lol. 375hp rating in chevelles/camaros, same motor in a 65 vette...425hp) The 325hp 396 stock was a DOG.The 383 b body stock 4sp cars ran 15.0 low 90s 91 92 mph stock a couple 14.7s@94
imo thats slow as chit for a big block 4spd the 383 was over rated from the factory the 340 under rated
Anything can be made to go with money even 301 turbo ta dog even the 305 chevy dog
Now those stroked 383s impressive numbers
mopar should have left the over rated engines to cheby
12 pages, dang... I think this goes to show both engines are good and have potential, if one was objectively better than the other all around there wouldn't be this much arguing. Just like the Chevy vs Ford vs Dodge pickup truck guys lol.
I didn't vote because I like both and each kind of has a different purpose, especially when they were new. 383 had the benefit of being around during the muscle car years but the 360 missed out, it didn't come along in HP form until low compression was the norm. I wonder how an HP 360 would have performed with 9.5:1+ compression like the earlier 340s had?
I've only had the opportunity to build up 360s in my own cars but I did overhaul an original 10:1 383 4-bbl in a 1969 Polara 2-door. In stock-ish form the 383 makes just a tad more torque but it's higher in the revs, that Polara was fun but didn't really start to move until around 2500 RPM or so even with the stock 4-bbl (non-HP/Magnum) cam (heavy car with 2.76 gears!). Every stock 360 I've driven including Magnums make tons of torque right off idle but quickly run out of breath around 4000 RPM.
Also an aside, in the BB block testing 440Source did they found that the main webbing on the 383 was considerably weaker than a 440 and way less than a 400, for those talking about high-effort builds. If I wanted more than about 500 horses out of a low-deck BBM full build I'd start with a 400 hands-down.
Me and you both!WOW!!!
I am a dinosaur, so I'll take the BB with all the terrible problems some have pointed out.

i knew a girl from Tijeras once. she liked to steal gold wrist watches and $10 bills out of my wallet.I have been to Tijeras. Beautiful place.
And that's the whole idea... not that anyone is wrong or right. It's really what each person prefers. There are 50 reasons to choose one or the other. Personal preference is what I was really afterClass racing is NOT what I am talking about. My friend raced Super Stock, I know most of what it takes. I am talking about street or street performance! Someone said 383's are dogs. That is not true, they are both in the same ballpark maybe a couple factored hp. Big deal. I prefer a 383 over a 360 and none of you guy's opinions will change that. Always have, always will.
My 318 dart smoked 325 hp chevelles easy and 350 hp chevelles if they coudnt drive if they could it was closeYet 383 cars smoked 325/350/360hp chevelles regularly. We won't talk about the L78s (real big blocks, lol. 375hp rating in chevelles/camaros, same motor in a 65 vette...425hp) The 325hp 396 stock was a DOG.
Stock? in your dreams.14.3@97 mph with 80k on it
383 gts 15.0 uncorked 14.8 slower then slow 94 mph trapStock? in your dreams.
A fresh super tuned 340 Dart would be lucky to turn that, and that's IF everything was right.
Ode to the mighty 340 hoping it doesn't come across an uncorked 383 GTS.
Didn't take that into consideration. Sorry. Duly noted. Thank you for pointing that out.Im not sure I understand. There is no modern 6.2 version of the 383. The magnum 383 still was discontinued around 1971.
Not much difference from a 383. Same strong block, forged crank, decent compression. Early heads only flow about as much as a 360 small block. The recipe is the same as any motor, get the best flowing heads first, and go from there.BTW.. for fairness we should be choosing 360 vs. 361... would see more fair...
No, the 383 had higher compression, 360's never had much since they came late to the game and began life, like the 318, as a low performance motor. It wasn't till they retired the 340 and gave the 360 the good stuff in 1974 that it went somewhere. Some of us noticed though, 360's used the same head castings as 340's and was a go to for good small block heads cheap.I would presume this comparison between a 360 and 383 would have similar compression ratios, cam, etc. to base a decent comparison.
I took it that he meant if both engines built the same for comparison.... kind of equal builds per say.No, the 383 had higher compression, 360's never had much since they came late to the game and began life, like the 318, as a low performance motor.

I think you'd be beyond impressed with a stone stock blueprinted 383HP in an A body with headers.....IF you could ever get it to hook up.I've never had a 383 in a A-body. Maybe it's time. I do know I've owned A-bodies with 360's, and it's almost next to impossible from my experience to keep them out of 13's. Any minor upgrades and it's 12's.
- Can you believe I ran 13.9's with a 2.45 geared, stock converter, and stock exhaust manifold 360 with the dished pistons and stock smog heads????? Cam was smaller than the Little Red Express factory cam? Like I say, they are the ONLY factory small block that you almost can't keep out of the 13's in a A-body. As you just read, I tried... LOL.
I would like to do that set up some day....I think you'd be beyond impressed with a stone stock blueprinted 383HP in an A body with headers.....IF you could ever get it to hook up.
The "only" change I would recommend would be to use Comp's version of the 383HP camshaft.....but choose one off the Oregin Cam master list. No way would I run a Comp camshaft now. Their version has a lighter LSA.I would like to do that set up some day....
I think it's time for you to stick a big block in an A-body. I think you won't be disappointed, in fact I know you won't.This in no wise means I like a 383 any less..
