Anyone have any live results with this cam in a 418? 242/250 .600"/.600" 114+3

I have a 418 with ported heads and ported intake with 125 NOS.

Never run it yet and wondering if it has to much lift?

242/250 .650"/.650" 114+3 with 1.8 rockers ( i have 1.7 rockers)so closer to .600 lift..

This is going into a offroad buggy that will idle alot and have to run at 1200 RPMs..

Well, running at 1200 RPM's with that duration n cubes, might not be the best. But once revved up a lil, should come alive ! The lift should not be a problem if your valve train can handle it.

I have stainless valves and double springs for .650 lift with shimmed springs for propper seat pressure...

I Got this cam trying to push the power curve up a little since i run 8.20 gearing in the axles.. Thats right i said 8.20 in the axles.. With a billet converter at 2200. 4l80e tranny. FMVB.

I want to rev this motor to 6800 all day but it has to Idle all day also..

I'd go with a custom grind cam instead of an off the shelf cam but that's just my opinion.

This amount of duration/lift should make 600-650 HP.

I have used these values, THOUGH I use a 118 C/L.

The wider Lobe Center will make your Rock Racer have a more even torque curve AND much better throttle control.
The "wide" centerline will also work better with increase compression.

This can be done by Crower Cams, ask for Ramero.

Thanks Lance I have 11.2 to 1 compression..

Does your EFI system have a timing retard for NOS?
I want to mabey spray...
