Cams

Twin Cam

Chain drive bolt-in Cam, no head work required. Works well at 9.1 to 9.5 compression. A very good combination with flat top pistons and stock heads. Horsepower and torque increase with smooth ride.

Performance street cam for 88" to 103" motors. Continuous torque from lower rpm, with smooth rideability and horsepower. Works well at 10.1 to 10.5 compression and will yied over 100 horsepower in 95" with good flowing heads and stock throttle body.

Specifically designed for 103" to 124" motors but works well in 95" motors with higher compression (10.6 to 10.8). This cam yields a torque band starting at 2000 to 5200 rpms and is capable of exceeding 130 horsepower with proper components. What makes this cam so popular is it ridability and it ability to make the number!

This new grind is a Hot Rod Cam for 95" to 113" motors. This cam was designed for 95" B-Style motors but has shown to perform well in 95" to 113" A-Style motors. Developed to make the power sooner in the torque band while still making power past 6200 rpm. 95" motors have produced 115 hp and 110 ft. lb torque while 103" have produced 125 hp and 120 ft. lb torque. Torque band begins at 2000 to 2500 rpm.

The T-Man Performance Cam of preference for motors from 113" to 131". This cam is featured in all of our JIMs' motors. It has proven to be the most consistent performing cam in big motor while yielding over 145 hp and 145 ft. lb torque. This cam also yields over 125 hp in our high-output 95" kit. What makes this cam so popular is its rideability throughout the torque band.

This is the Daddy Rat of the Street Performance Cam Shafts. For the ultimate build, this cam requires higher compression ratios (11.5+) to reap its benefits. We strongly suggest talking to your engine builder to make sure this is the right cam for your combination. Designed to run with T-Man or comparable valve spring packs. This is a BRUTAL street performance cam that will run on pump gas.

Designed for Race Use but has been used in street applications. Please call for details
