What are you using this motor for Racing or strictly for street?

Beeks69

Mainly street and maybe 1 or 2 track times a year.

What stroke on crank are you using? Stock 4.25 or offset 2.20 chevy ect,ect.I can tell you this much you are over 400 hp.but below 475. If i had a pipe max program i could run it threw and see what it spit out but i don't.

Beeks69

Using the stock 4.25 stroke. Thank you for your info I was hoping around 450 hp but not sure about guessing on torque numbers.

450-475hp, 525+ on torque.

I had a similar engine dyno last year but 10.25:1 compression, Torker and slightly more cam. It made 485 hp and 522 TQ with an 850 AED carb on the engine dyno. Yours' will make a little less hp. My guess is you are making 1 hp per CID at 468 hp and 520 TQ.

I think you are close Dave could be slightly lower. I know of one that has Torker also with the same cam basically but a 825 carb. This engine hasn't been on a dyno but runs 1150's/11.60's with E iron heads gasket clean up only.Less ci 461.
