Hi, I'm new here. I don't have a truck but I am working with a truck engine, and that's why I decided to ask for your elp here.

Anyways, I'm getting ready to work on a 5.3 lm7 to put into my firebird. I plan on running milled 862 heads about .030. I'm thinking about installing 4.8 flat top pistons. To also help bump up compression. Ive herd these pistons will work and I've heard they dont. Do I need to get the 4.8 connecting rods too or can I put them onto my 5.3 rods? Thanks
