Hey guys, thanks for all the replies. I looked up the horsepower and torque rating for an 01 lm7. Said it was 285hp/325tq. So if I added full exhaust, cam, and air intake. I'd probably be looking at 330hp/375tq. With a good tune maybe more. I really want to go with this engine since the biggest thing I'll be hauling is a spray rig that weighs about 2500 pds. So what would be a good cam to go for this setup? definitely want to increase my torque as much as I can without affecting driveability. Want it to run like a stocker.
