The cam specs will dictate how much and where, as well as how long it will hold after peak... Not enough detail for a real good guess, but i will play anyways! 837hp@ 6,800 rpm. Good luck  Arnie
67 Cuda 8.48@ 158.7 mph 1.18 60' 2,600 DA(so far...)
70 Super Bee 440 Six Pack 4-speed. 13.2 @ 104 Stock exhaust/Street tires.

I'll take a SWAG, on your dyno 900+ HP at or above 6300 RPM with 810 Ft. Lbs , on my dyno 845 HP with 775 Ft. lbs at 7000 RPM and on Drams dyno 510 HP at 5900 RPM with 550 ft. lbs on FL pump gas    All kidding aside that motor should make 900 + HP on pump gas, be very careful on the ignition timing, spark plug heat range and jetting, richer is better to start with along with a cold plug

on pump gas with a 3/4 cam I doubt it.

Yep a pretty piston, if ya got the other 7 to go with it. I gotta ask, is this the first aftermarket piston you have ever seen??? What do you expect it to look like, one of your old ones? What will it dyno?? Without cam specs this sounds like a chebbie post, with the secret 3/4 cam crap.  Everytime Ive heard some chevy redneck galk about there 3/4 cam, yep they run 9-s...in the 1/8. But all BS aside good luck with the new motor, alot of time, money and hard work and money Did I say money  Dyno it up here, it might make 650hp....take 25% off at a REAL 8400FT. Quote:
sure is a pretty diamond piston though!

I'd just start another thread on that and I'd bet some of the top experts will comment on that! Just a hunch but they may tell you .040 is tight for BB and .055 may be the limit... Ask them though!

@ this point I have no intention of building a big block so I really don't have to know the real answer, you didn't say on piston wall clearance so if they are loose and rock a lot than .051 may be fine I thought it was a simple question cause this is for the most part a big block thread  ....
