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!

BTR's .560" lift LS6-style valve springs gives you all of the performance of the venerable OEM LS6 valve spring (GM part # 12499224 or 12586484) at a fraction of the cost. These springs pair perfectly with our Low Buck Truck (or other 550-lift) cams. They are also a great option for replacing worn out or broken springs in stock applications. Specs are below. These spring utilize the stock retainers and keeper-making them easy to install.
Have not fired motor yet. But, the shipping was spot on and all components look really nice. Excited to hear it run. I'll be a customer for more LS goodies.
