hey bro, go here and read on! tons of info on the vortec 454's. i am running a kit from summit with cam, lifters and the adjustible timing chain. had it reprogrammed, and added the bigger lt-1 injectors. it does decent on mileage for a big sled, but now has waaaaaaaaaaayyyyyyyyyyyyy more power than stock. gm cut the cam shitty and it kills the power on them.... later, brian
