thought it was a standard block. it's not. bores are good. are there any 010 over pistons other than cast oem truck pistons available anywhere?

Yup

for the right money,,you can get any size you want.

Whole idea is to save a decent bore. For the right price in my case is standard off shelf stuff. I would never buy special pistons for an old hole.

I bought a set of Diamond Forged that were an odd size (4.565") for just about the same price as a stock size from my engine builder.

I've been known to find a piston then match the block to them before. Sometimes you can find some great prices on oddball pistons sizes and a time or two it was the only piston available. Wouldn't worry about going 10 or 30 over.

A few years back, ok many years, they would knurl the pistons and use .010 over rings.
But if you have to bore, why not just go to .030 over?

i have a .010 motor with 2 bad rods. bores and flat cast-i think-pistons are nice. pressing rods out of pistons frequently kills the piston. usually done to replace the piston, not the rod. if i can find something like 2399's or even hyper flatties i would have some options for saving these bores. this is about the biggest pool of knowledge on big block chebbys there is. so i guess my question is answered...no.

Might not for an ol ho but would consider for a new ho. Lol
