From these specs ,What would be your thoughts on how this will perform in a weekend cruzer ,at 3500 lbs with a 4.11 rear end and stickshift.This is my engine specs for the truck I am rebuilding. thnx for any feedback.The only info left out that I saw,58 cc heads and 8cc dish piston..010 under mains and milled heads,so the chamber may be 1-2 cc smaller and decked block.Plus I have installed rhodes lifter,which claim to knock off about 10 deg. under 3000 rpm of cam duration,the actual cam is xe262 flat tappet hydralic.
