solid lifter cam

solid camshaft to suit the Ford Cleveland 351. It is a Ivan Tighe camshaft grind #764. The specs are:Int 292 Dur, Exh 298 Dur. Int 256 Dur @ 0.050", Exh 261 Dur @ 0.050". Int 0.614" Lift, Exh 0.622" Lift. Int clearance 0.022", Exh clearance 0.024

anyone heard of these specs being used in an engine before?

It's very similar to the Crane F256. It should make decent power up to around 7000rpm. It'd be a nice topend camshaft. Would be requiring 4.11-4.5 gears and a 4500-5000rpm histall.

Street use nope but it'd be fun anyway.

Re: solid lifter cam

i,ve used a cam around this size on a street clevo with 4.11 gears and it was great.pity the owner of the car was a bit limp wristed and thought it was too radical and so i changed the entire top end to a smaller hydraulic setup.2 weeks later he sells the car to buy a Hyundai excel.How gay can you get!sorry,seem to have gotten a little off track here.If my memory serves me correctly wasn,t Tighe responsible for DJ,s cams in his xd,xe days?

Re: solid lifter cam

Agree with that, the more compression you give her the less wild it will feel. It's bigger than the cam I'm running, and I wouldn't want any more than that one in a street car.

Agree with that, also that the more compression you give her the less wild it will feel. It's bigger than the cam I'm running, and I wouldn't want to run any more than that one in a street car. Choppy idle, rough running up to 2500rpm.

Re: solid lifter cam

What I mean is that cam of size x in a 9:1 compression engine feels bigger (ie peakier, choppier idle, higher power band) than the same cam does in the same motor with 11:1 compression.

So from most cam charts around, your size cam would be recommended for somewhere between 10.5:1 to 13:1 or more, but the higher compression, with all else being equal, would provide an easier motor to live with. Albeit you couldn't run PULP.

Has to do with torque potential and other things that occurr at the higher compression ratios.

Re: solid lifter cam

I ran that cam in a 1730kg falcon in my old motor but it only ran 12.62@107mph. The problem was it only had about 3000 stall and only 10.2-1 comp and that was running a full exhaust system. Ran on optimax without a problem. New setup is much milder but a lot stronger.
