BBC 467
10.6 compression
Isky 238/248 - 578/608 - 109/105 billet hyd roller
AFR 305 heads, performer RPM intake
950 Pro systems carb.
648.9 HP @ 6400 RPM 619 TQ @ 4500 RPM

That's similar to my 454 with minor differences. Same AFR 305 heads, Comp custom 242/248 hydraulic roller with .638 lift. My compression is only 10.2 and mine is only .030 over. I built this engine 20 years ago myself. Used heavy TRW slugs with large 5/64 ring package and standard tension oil, so I give up a little HP there too along with the smaller bore. RPM air gap out of the box with a 1" open spacer, and a 950HP also built by me, made 608 hp at 6300 and 589 tq at 4400. I've been happy with it.

That build even 20 years ago wasn't cheap. Heads alone were $3000 back then.
