I just saw a post on Chevelles.com about the 8.1. Look up raylarengine.com and check out what they have. Heads, intakes, cams...they say they can push it over 600 hp with bolt ons. They even have a Gen VII 600 cid block. 765 hp and hp and 825 tq with 700 rpm idle on 89 octane gas. That one is a turn key marine engine but with a few mods who knows? Big fun huh?
Good luck!
