Lets just say you have 2 identical camaros, with the same suspension, weight, rear end, horse power, torque ext... you get the picture! But one of them is a 350 and the other is a 383, shouldt the 383 beat the 350 in the 1/4 mile? this question popt in my head today and its been buging me all day. ive askt some people and some of them say that it would be a tie and others say that the 383 would win because of biger cubes, so wich one is it? Also lets supose all you guys agree it would be a tie, then whats the point of going bigger cubes? THANKS!!!

in a perfect world....if you drop a pound of bricks and a pound of feathers off the roof of a building which one would hit the ground first??? they would both hit at the same time in a perfect world...

Please don't make the same thread in more than one section...

And it couldn't be the same set up if the engines are different. Lets say the 383 and 350 (346 if your talking stock Ls1/6) share the same cam, heads, etc as much as possible that can be the same...

The 383 will have more tq and hp due to higher cubes and will have more area under the curve.

383 > 350

if a perfect world involves no air resistance than yeah that would be true, but that has nothing to do with the question

if both cars had the same horsepower and torque at their peaks than obviously they would have to be making their horsepower and torque peaks at different rpms it would come down to which engine could take better advantage of the gearing

it would probably go to the 383 because with more cubes there would be a better chance of being more average power under the curve or more distance between the torque peak and the horsepower peak

"There is no replacement for Displacement"


More displacement = More capacity for air/fuel = more air in and out = more power.

Also a 383 is stroked meaning it will have a faster piston speed which means your gonna go faster.

+1 for 383

this is stupid.... a 350 and a 383 shouldnt be making the same tq and power..... even if they did make the same peak numbers, the 383 would have a better curve. but even then, the race would come down to the driver.

Well this is pretty much IMPOSSIBLE... but if you had 2 Fbodies one with a 350 the other with a 383 and the cars were EXACTLY the same power curve, torque, rear end, and weight, they would finish at the same time.
And now a days the whole "theirs no replacement for displacement" is really not true when you consider technology now a days (turbos, superchargers, N20)
And with your theory "OH its a bigger engine so it will win" their are people little 2.0 L engines that would run laps around a LS1

ya and those lil 2.0L's have about 22-24lbs. boost, where as the "No replacement for displacement" usually deals with N/A applications.

Last year in Gm High Tech Perf. did a test on the new 6.0L GTO STOCK and the 2002 WS6 346 LS1 STOCK both 6 speeds and spraying the same amount of nitrous.

Guess who weighs more? THE GTO
Guess who won? THE GTO
Wondering why? Displacement.

They both sprayed at the same time.

We are not discussing Forced Induction applications, and no we are not talking about Formula 1 race car motors either.

No question the 383 wins

what?

first, just because it is a 383, doesn't mean its stroked because you don't know what kind of engine he is talking about. It could be just bored out, or a bigger engine that is destroked.

second, piston speed has nothing to do with how fast your going to go.

Given the context of the discusion and the site it's reasonable to assume he's talking about an ls1 383. Which will not be an all bore destroke engine

thanks for the rebound

BrandonDrecksage

given the fact that he listed 350 as the size, its not resonable to assume anything.

What about the piston speed? Have a response for that...from yourself?

There is no replacement for displacement, period. Just look at what the top fuel guys are running.

ok you win. He was talking about an all bore old school iron block vs an old school 350. I'll still take the 383 over the 350 FTW. And to be honest with you I have a race similar to this coming up. I have a friend with a 388 that I'm going to race. Our cars are similar in build both with 9inch rears and 3.89's. He's making about 65 more hp and maybe 80ft tq than me on the dyno. Given equal traction and driving skills. I dont see me wining without using my n2o.

You guys are reading into this too much.

The 383 has the edge, plain and simple, for the same reason an Ls1 has an edge over those silly VTEC motors. More displacement=more power (generalization but so is this thread so it works).

stokedporcupine

no, i think the question just is very poorly thought out

^ Im new to this whole performance stuff!!! and you where all there once and the only way im going to learn is by asking questions, some wich will be stupid but so be it!!! so **** off!!! and to everyone else that has helpt me with this question THANKS ALOT!!!!
