Thanks for the input guys. Wow was aware the 4.8 compression was so low. Ill go with a good dual valve spring. Mill the heads about .020 and port match the to a high flow intake. Guess ill go 5.3 or LY6 if the lil 4.8 has crappy compression.

Vic JR sound good for intake? Should i run a elbow and a 90mm tb or a edelbrock carb style throttle body that flows 1000cfm?
