The TSP Cathedral 3/4 Race Cam is a modern throwback to the old-school small block 3/4 race cams — reimagined for cathedral-port LS engines. Built for 5.7L and 6.0L combinations, this cam delivers hard-hitting mid-range power, a deep choppy idle, and +75 HP gains over stock in real-world dyno testing.
Tested on a 10:1 compression 370 CID LQ4 using stock 317 cathedral heads and a TBSS/NNBS intake manifold, this cam picked up an impressive +75 HP over stock. Expect strong gains with a wide powerband and that signature lopey idle.
If you're running cathedral heads and want an LS cam that hits like an old-school small block, the TSP Cathedral 3/4 Race Cam is your go-to for chop, torque, and tire-frying performance.
