Quote: If I could go back and visit myself in 2004 I would have ordered dished pistons and zero decked the block. This would have put me in the mid 9s with quench. I probably could have run 87 octane while still making plenty of power. I could still do this, but that would be another $1000 in parts, machine work and down time.
Just an FYI my 493 has zero deck with IIRC 34cc dish. 8.9something:1. Basically makes 500hp and 600 ft/lbs with a .509 cam and it is quite happy to do it with 87 regular on all but the hottest of days.
