i have been thinking along the same lines. i have a chevy 235 in by '59 chevy truck and was considering turbocharging. does anybody know the point the valves float or lifters collapse. if those are the main two problems, can't you just get stiffer valve springs and better lifters?
can the stock crank, rods and pistons handle a low boost (8 psi) application, reving to 6000 rpm?
i would like to get some details ironed out, because if i cant turbo this sucker, i may have to be replaced with something with 2 more cylinders.
