I currently have a 5.3 ls and a slue of different small blocks. Along with many other people I'm undecided on which engine to go with or which type of power adder. The car currently runs 13's, but I'm trying to get to the stripe before my father in his '69 Chevelle. I've currently QA1 suspension in the front and a QA1 pro coil over kit for the rear. The rear end is also getting swapped out for either a 9 inch or a 12 bolt. Whats working and whats not?
