Current engine being built is getting a 70's era Crane solid flat tappet with mushroom lifters. Over 400 lift at the lobe with a 1.65 rocker.

Mine will be a solid roller. Engine is in the build stage right now. I like my hotrod car a little on the extreme side.

I have in my car right now the Crane Blue Print RA IV cam, & I've used this cam in the last 4 engines I've built. This cam is the same cam that is / was in my 462, 455 + 30 over. With E-heads performer RPM intake, RA IB cam , 1:65 rolloer tip rockers, Eagle H-beam rod, SRP forged pistons, Crane anti-pump up lifters, dbl roller chain & gears, Eagle cast crank, Pertronix Ign., 8mm Taylor wires, & topped off with an 800 cfm Q-jet,(tricked out) & an M22 with 3:73 rear end,RA IV cast iron exhaust manifolds, in my 73 GTO & it went 11:72 @ 122 mph. This was done on street radial tires.

My cam is SFT. CC 290b6, sounds great on a 106lsa but I might go roller over the winter. I like a cam that shakes the car siting next to me,but want the performance to back up the nasty idle.

Was a solid roller, 248/254 .625 114 Crower, machinist/builder talked me into a XE288HR (236/242 .520/.540 110) on a refresh, unsure if I will run it or not.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
