Basically I have a 1996 Tahoe 2 door 4x4 and just found a huge crack in the L31 Vortec 350 so that engine is going bye. I just bought a 2001 Camaro SS and am pulling the LS1 5.7 to put in the tahoe. Considering this thing weighs about 4700 pounds I should get rid of the "car" camshaft. The tahoe does have 3.73 gears at least with 30.5" tires. I'm going to have 1 3/4" long tube headers, 2.5" exhaust, air intake, electric fans, STOCK STALL CONVERTER, either a TBSS intake manifold or LQ4 intake manifold, and 241 heads. I can upgrade the valve springs if needed. I do want something that is capable to tow if I need to, which would be pretty rare. It would be nice to find a cam that increases low end torque and some horsepower up top (which isn't as important) and gets around the same mileage as the stock cam. I would prefer to find a cam with .550"/.550" or less valve lift since I want something reliable, and emissions aren't as issue since I'm in Nevada, but it would be nice to not have a smelly cam. Max rpm for the engine would be 6000. Thanks for any help.
