Default stock short block 350 vs. 383???

Is it possible for a Wild 350 to make more hp/tq than a Mild 383?

Yes it would be possible to make more hp, but not low end tq. most wild 350's will have to sacrafice tq to make max hp. more displacement balances out that loss on one end to gain at another equation...

Yep. I make ~360rwtq at 2800 too so I'm not lacking in the lowend torque department either.

The answer to your question is yes. And it doesn't have to be a "wild" 350, just a well built, well spec'd one.
Mine puts down 384 rwtq SAE.

Not a mild vs wild thing, a WELL DONE 350 will make more power and be faster than a popularly done 383.

I started typing before bowtienut posted.
We have very similar setups, just his is more strip and mine more street, neither of us has had great weather yet either.

reading comprehension must not be stressed in new orleans... believe it or not its possible to make low end torque without a hotcam!!

fwiw... a well done 383 can make more power everywhere than a well done 355. if you're doing things "right" on your "wild" 355, the cost difference is very very small.

From what I am reading its more of a tq difference than a hp difference.

and if you I'm talking about a stock short block not a 355...

No. Torque is Horsespower... But it all matters how efficiently that equation is put to the wheels...

Ok speed_demon24, If you were to take your exact top end setup and put it on top of a popularly built 383 do you think it will be much of a difference?

a well done 383 v. a well done stock short block will end in the 383's favor all day in the tq department. 383's are known for making gobs of torque unless you spin them. FWIW spend the money on a long rod (6") 383 and make so much tq it'll want to twist the chassis....again it needs to built right to do it, otherwise you just have a big paperweight.

Define wild 350. NA it is possible to make more than a 383, but the 383 has to be really mild, maybe running a hotcam or a CC305. But usually a 383 is better everywhere. In super chevy they just did an article on a 355 vs 383 with the same parts. They had the same compression, cams/heads/intakes/exhausts. the 383 made more power everywhere. You could also spray the hell out of a 355, that will make more power

Peak power probably wouldn't change much but it would probably pick up 50+tq across the board which would be fun for a street car. Street manners would greatly improve as well.

They will but if the heads are only going to be some big it may be better to stay 350/355.

A well built dialed in car will quick regardless of the cubes. The stall, cam, gear, susp, etc will all play a role. Dont worry about building a big or small motor, address all areas of the car.

Well put. Very few combinations on here are well thought out.
