For a driver, its totally possible to do this on the cheap if its all in good shape

I would respectfully disagree with replacing the wrist pins if doing a super budget, ball hone overhaul. Removing wrist pins from factory cast pistons and then replacing them is a losing proposition from my experience. We have the high dollar Sunnen pin press at my shop. But almost always ruin 2-3 pistons pressing the pins out. Our rule is if the pins are pressed out, your getting new pistons. Pontiac rods take 1800-2500 lbs press typically to remove. Very hard to avoid bending the pin box. Full floating pistons a completely different situation of course. Our experience on a typical V-8 is: Ball Hone, re-ring with OE pistons vs proper overbore and plateau hone with torque plates = 4-6 HP loss per cylinder. So 32-48 HP loss doing a backyard style overhaul. Budget will determine which way you need to go.
