Buddy is looking at getting a 76 Chevy C30 dually with a 454. Has 360k miles on it mostly towing so it needs a bit of a rebuild. only thing that is known to be wrong is a sticky valve. I figured strip it to the block then have the heads cleanedup, planed, and hone the cylinders or maybe just bore it like .030 over. Get a rebuild kit and put it back together. Anyone had experience with anything similar? Just time consuming I am guessing. My buddy wants to build it into a street truck. Tuck some big as drag radials inside them dually fender wells and lower it a bit.
