Poll: Type of Camshaft in Your Street Pontiac
 

What type of camshaft are you running in your street Pontiac?

Here are the 4 poll choices:

Flat-tappet hydraulic

Flat-tappet solid

Hydraulic roller

Solid roller

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!

Hydraulic roller when I build it.

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.

Stump Puller HR, combo in signature

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.

Solid roller in the 70, 10:8.1 pump gas
Hft in the 68 for 20 years . Hyd roller 400 on engine stand ( back up engine)

I've got the Crower 60243 HFT in my 9.5 to 1 462.

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.

SR in mine. Comp XE Street Roller lobes. 254/260 @ .050. 112 LSA and 108 ICL. Right at .650 net lift.

HFT in the wife's 76 T/A with my old 400. Lunati Voodoo 10510703 227/233 @ .050. 110 LSA and 106 ICL. Right at .500 lift.

Solid flat tappet in my 9.4:1 462

HR in my GTO and '68 Bird…but I'm getting really tired of playing wac-a mole with lifters so not sure what will end up in my Formula's 535.

Nunzi spec solid flat-tappet in my 428 with 722 heads.

hyd rollers in 2 engines,one with solids on it soon to be changed to hyd.2 with hyd flat tappets.Tom

041 with Rhodes and 1.65 roller rockers.

A bunch of Melling SPC-7\068 clones in my cars...
