Hey guys I have a 2002 LS1 that was removed with 6k miles on it. I wnat to upgrade it without getting to wild. NO NOS and no forced induction. I really want a good running engine for a weekend cruising 91 chevy extended cab... I have a 4 link and a 3.73 positrac rearend.

What is a good streetable combination that will yeild me some good times

I dont; mind doing a head, intake tb change but really wanna leave the lower end intact.

I have the 4l60e that I plan on putting a billet servo and transgo kit in the tranny, and adding an upgraded converter. What combinations do you guys prefer?
