Re: Ls7 454
I would never use that old technology. I built a flat tappet 468 with oval port heads on it that made 670 h.p. right after an LS-6 made 452 h.p. on the same dyno. The torque on my motor was 632 and the torque on the LS-6 was 520. I think camshaft technology has came a long ways since the seventys, even with the flat tappet stuff. Granted mine had a little more compression and good port work in the heads but I bet I had less money in my motor than the guy had in the LS-6, he payed someone to go thru his. I've been in a car in the past that had and LS-7 in it with a roller cam and I can tell you that thing was a pussy cat compared this thing.
