2 of my buddies had 4.8's one with the tsp 220 cam and the other with a tr220, the one with the tr and 1"3/4 made 319 hp in 3rd on the dyno, and the other made 336HP in 3rd on the same dyno, same sized tires, and 3.73's in the rear. not much of a difference, but i want the same setup as the tsp220 cammed 4.8, so i can smoke him with my manual
