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.

Old Crane solid roller version of the RAIV/041. Isn't made any more but I got it cheap so decided to give it a go and it works pretty good!

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.
