The Texas Speed B.F.D. Chop Monster 5.7/6.0L Camshaft was designed to spec with Hoonigan's Chop King, Zac Mertens, to give a naturally aspirated LS the most savage chop possible while still making big power through the curve. Ground on a tight 108 degree lobe separation, it is the loudest-idling grind in the Texas Speed cathedral-port lineup and is best suited to 5.7L and 6.0L engines.
The cam measures 233/240 duration at .050", .629"/.600" lift, 108 LSA and a 106 degree intake centerline across a 2,300 to 7,000 rpm operating range, and Texas Speed estimates a gain of 65 or more horsepower. It requires TSP .660" dual valve springs, a 10.5:1 or higher compression ratio, a 3,600 rpm or higher stall converter in automatics and at least a 3.42 rear gear. It fits stock untouched heads with no piston-to-valve clearance issues, though measuring is always recommended. Texas Speed recommends it mostly as a weekend warrior cam on stock cubic inch engines; it can be daily driven in automatics with good low-speed tuning and a properly sized converter, while manuals need more thorough tuning.

FAQ
What engines does the Texas Speed B.F.D. Chop Monster 5.7/6.0 cam fit?
This version of the B.F.D. is best suited for 5.7L and 6.0L cathedral-port LS engines such as the LS1, LS6, LS2 and LQ4/LQ9. Texas Speed makes other B.F.D. grinds for the 5.3L, 6.2L, LS7 and stroker LS engines.
How aggressive is the idle on the B.F.D. Chop Monster cam?
Very aggressive. The 108 degree lobe separation and 106 degree intake centerline were chosen with Hoonigan's Zac Mertens to produce the most savage chop possible from a naturally aspirated LS, and Texas Speed rates the chop level as very aggressive.
What converter, gear and springs does the B.F.D. cam require?
Texas Speed requires TSP .660" dual valve springs, a 3,600 rpm or higher stall converter in automatics and at least a 3.42 rear gear, along with a 10.5:1 or higher compression ratio.
Can the B.F.D. Chop Monster be daily driven?
Texas Speed recommends it mostly as a weekend warrior cam on stock cubic inch engines. Automatics can be daily driven with good low-speed tuning and a properly sized torque converter, and manual cars need more thorough tuning.
How much power does the B.F.D. 5.7/6.0 cam add?
Texas Speed estimates a gain of 65 or more horsepower from the B.F.D. Chop Monster on a 5.7L or 6.0L LS with the required compression, springs and tuning. Results vary with heads, intake and exhaust.
Will the B.F.D. cam fit stock untouched heads?
Yes. Texas Speed states the B.F.D. 5.7/6.0 fits stock untouched heads with no piston-to-valve clearance issues, although measuring clearance is always recommended during any camshaft installation.
