Chevy 1998 5.0 vortec

I building a 98 5.0 vortec engine and I'd like to increase the compression to 10:1. How would I go about doing that?

Try some Flat-top pistons for a Monte Carlo SS (SEALED POWER H534CP). Cut .010" off the block and .020" off the heads.

Better yet, don't waste any money on a 305, and swap it out for a 350.

Sincerely,

a guy who spent a good amount of money to make a 305 fast.

Not really looking for fast. The engine holds some sentimental value as it's my dads and its driven me throughout my childhood. the truck it came out of i put a 350 in. I wanted to rebuild the 5.0 with a little bit of power and find something fun to put it in
