Check out our new TSP L99 Stage 4 VVT camshaft! Since we are one of the only companies that designs, grinds, and tests our camshafts in-house, we are able to constantly test for better lobes, grinds, and combinations! Our camshafts are the result of endless engine dyno testing on our SuperFlow 902 engine dyno using a factory GM L99 engine with factory cylinder heads. Our L99 Stage 4 camshaft will be a great choice for those looking for the most power possible from their L99 engine! This camshaft will have an aggressive lope at idle and will drive well with a minimum stall speed torque converter of 3,600 RPM. This cam makes more power than the factory camshaft from 3,000 RPM all the way to the 6,600 RPM peak. Cam Specs: 235/247, .649"/.629", 113 LSA
