The Low Buck Truck cam is the most popular cam we offer. It offers gains of 60+ hp over the 4.8L, 5.3L or 6.0L stock cams. The Low Buck Truck cam is perfect for daily driver and works with a stock converter, but a higher stall will improve performance. This cam requires .550-lift springs and can be run with stock LS3/LS6 springs or aftermarket 550-lift springs. The cam requires a tune. This Low Buck Truck cam has been extensively dyno tested and has been run successfully NA, with every type of blower (centrifugal, roots and twin screw) and with a Turbo. It works very well under boost.
The Low Buck Truck also makes an amazing TURBO cam. The low-speed torque offered by the Low Buck Truck makes for awesome boost response, and you can easily exceed 1000 hp with a Low Buck Truck with the right turbo. On this test, we ran a junkyard L33 5.3L with the Low Buck Truck cam and springs package, then added a single S475 Borg turbo. The NA motor made 422 hp (adding 60+ hp over stock), then made 620+ hp at 7.5 psi, then 920+ hp at 17 psi. This cam (like most) works very well with boost!

Parts arrived in a short period of time and were packaged very well. The added horsepower was immediately noticeable.
Very affordable cam and spring package.
Has an awesome idle sound.
Truck runs great and pulls well from 3000 rpm up. Also truck is a manual transmission. No drivability issues at all
Great value from a known expert. May be a while before I get it installed. Taking out a Sloppy stage 2. Can't wait to feel the increase in torque down low. It's a 56 chevy 6.0 TH400 so about 3700 with me in it. Kind of a bar hopper hot rod. All I care about is street light to street light.
Just finished installing this in my 71 blazer with an ly6. Still working on the tune but she is pretty peppy now. Didn't notice any loss in low end and anything above 3000 rpm is much more responsive.
Was on back order and still showed up within a week. Cam was packed very well, plenty of wrapping! Communication on the teams part was spot on! Can't wait to fire this in the truck and listen to it chomp.
