I have a 94 Z28 and I am converting it to a LT4. I don't know what to do to my pistons, I am definitely redoing them but I'm not sure to bore it over and make it a 383 stroker for more torque? Or to make it a 355, just not sure what to do to make them most power out of it. So if someone knows alot about lt4's or has one, please give me some advice.[/url]
