Another hp guess

Post  tconnection on March 10th 2012, 11:05 pm

Im waiting for the shop to get done with my block which will be ready to assembly when i get it home.
Im kinda wondering about what hp range it will about be in.

2.35 int valve
a460 head, figuring 440 int flow
The int has the ports smoothed and gasket matched
839/780 lift, 283/302@.050, 316/340@ .020, 114 lsa
1250 or 1300 cfm carb
im wanting .002 to .002.5 on the rods and .003 on the mains.
Thanks

You should make between 960 to about 975. You need a few more cubic inches, and a little more airflow for 1000 Hp. Probably get some custom pistons with a lightweight ring package and finesse things.

Grrrrrrrrrrrrr! I hope trick flow aint doing it like that. The 2.30 int is what they say flow 412cfm out the box. I think the 2.35's is a little better. Anyway what ive done is polished all ports smoothing sharpness out of the short turns and sharp edges out of the bowls/pockets.
Thanks
