I plan on doing a 355 build with a set of LE2 heads and cam from lloyd. I have a 1997 ws6 Trans am with 125k miles on it bone stock. What else will I need when after i do my 355 build and get the LE2 package and cam? This is a street car half way a daily driver. I was interested in the College budget 355 LT1 rebuild with premium Mahle pistons 355 build. What supporting mods will i need and a new rear end and transmission?
