The Texas Speed B.F.D. Chop Monster LS7 Camshaft is a naturally aspirated grind specified with Zac Mertens, Hoonigan's Chop King, to give the 7.0L LS7 the most savage idle possible while still making big power through the curve. Ground on a 108 degree lobe separation angle with 245/256 duration and .657"/.655" lift, it is the LS7 member of the Texas Speed B.F.D. camshaft line.
Texas Speed estimates a gain of 80 or more horsepower and lists an operating range of 2,400 to 7,000 rpm with a recommended compression ratio of 11.1:1 or higher. The TSP/PAC .700" dual valve spring kit is required, automatics need a 4,000 rpm or higher stall converter and a 3.42 or deeper rear gear is suggested for best performance. Texas Speed says the cam can be daily driven with good low-speed tuning and a properly sized converter, while manual cars need more thorough tuning. It is supplied only as a 3-bolt camshaft.

Do I need a stall converter and gears with the Chop Monster LS7 cam?
