    If you looked hard enough, and dont give up, you could find a 5.3 or even a 6l for cheap. I bought my roll over from a body shop for $300 plus tow bill

    Other than springs Rockerarm bearings and pushrods not a whole lot that wears out on these motors. The bottom end goes to 300k without blinking in many cases.

    Gears, stall, bolt ons like CAI, LTs, then cam and then turbos. Yup 2. I got a 4.8 it suks down low but with, 4.10s 3200 stall and TSP 220 id does pretty good on takeoff. It will burn through 80% of 1st gear. Mine does.


    4.8, TSP 220, 6L90 swap, 3400 Stall, 4.10s w/30" drag radial and T76 @ 16lbs.
