880 vortec blocks, what pistons?

I think you can still buy the shortblock from GM. Years ago I bought 2 or 3 of them to replace rod knocking L31 lower ends. Back then they were far cheaper than the L31 crate engine and being a short block that allowed you to pick what cam and heads you wanted to run.

Do you still have a part number? That'd be a simple and easy way to get a decently-equipped "new" short-block.

Both are far more $$$ than they were but everything is higher now including machine shop labor. From what I understand, GM moved the manufacturing of these engines back to the USA from Mexico as well a couple of years ago. I completed engines for a couple of customers years ago from these short blocks. One had Edelbrock heads and the second had AFRs put on them. GM roller cam fits right in either. To my knowledge both are still running well.

Last year when I was looking for a ZZ4 short block they weren't available. The Blue Print 383 is cheaper plus it come with the cam, timing gears chain, and cover, hmmm.
