All things being equal what would the HP/TQ numbers be with a 350 vs a 383? Or how much more would I get from a 383? Thanks, Mike

For whatever reason, 383's seem to put out a little more than the ratio of displacement. But, that ratio is a good place to start.

To get more out of it, u gotta stroke it!

Youll get a lot more low end power with a stroker, seeing as how its essentially that, a STROKER. But, if u on a budget, a 350 wud suffice.

U can still build up a 383 to turn 7k, but with that longer stroke ull need to get some good main caps and rods do u dont break anything!

So would I basically just get more torque and the horsepower be about the same as the 350 if I built a 383?

No, more torque means more horsepower, because HP = torque x RPM / 5252.

If you're looking to spin 7,000 RPM you'd be better off with a 377. It's a destroked 400 (you use a 350 crank in the 400 block).

A 383 will make about 45 lbs/ft. more torque and have a broader, flater torque cruve than a 350. What was said about torque equals horsepower is dead on. A 383 won't be as rev happy as a 350 though. More rotating mass to get moving. A 383 is a street king though becuase of the torque. For the track the 377 is a hotter setup.
