I've got a 350 shortblock with flat top pistons today that I'm gonna rering and run till I can afford my 383. I've got a 1983 305 in my truck that i'm gonna steal the heads off of. I know that the ports are way too small but i'm trying to keep the budget below $350 to $400 and I don't plan on pulling it past 4500 rpm. I'm gonna order one of PAWS $80 cam/lifter sets so I need some specs. I'm thinking i need a cam with mild lift, lots of duration and small overlap to make up for the crappy heads. What do yall think?
