Hi guys something let go in my current 464. The motor is 8 yrs old many street miles lets say 10k, has 50 track passes plus the usual flogging it on the street. It has Eagle crank, Scat rods, CP pistons 10.5:1 .040 over, Erson rockers, Hooker 1 3/4 headers, 3 inch exhaust, Fidenza 13lb aluminum flywheel. Cam is similar to a comp 294 (custom grind by builder), street master port matched, Holly 850, Msd dist locked timing. Barrys Edelbrock heads pro ported flows 330 @.600. This combo made 415 rwhp at 5800.
What would I need to do to get to 550-600 hp on pump gas? I am assuming it spun a bearing at this point crank is probably toast. Block is good so are the heads. Lets hear opinions.
