Does anyone have the specs of the Supercars Unlimited "just plain nasty" cam they used in their race car? All I vaguely remember is that it was the same as a W30 manual trans 328 duration cam except it had an extra 20 degrees of duration on the exhaust only (348 instead of 328).

 

This is an old Supercars Unlimited catalog said about the "just plain nasty" cam:

"This is a brand new duplicate of the "factory" 328/348 cam used by several record holding 455ci drag race stockers. Based on a 107 degree lobe centerline, this cam features 243 degree intake duration and 262 degree exhaust at .050", .475" valve lift. Very rough idle. Use with 4 speed or automatic with 3500-4000 rpm stall converter and 4.33 or lower gears. This cam is just plain nasty sounding! Produces outstanding horsepower and torque to 6000 rpm. Will pas NHRA teck for stock eliminator. 39 degree bank angle."

Hope this helps!

Thank you very much. I couldn't find my old catalog with that paragraph in it. Now to find someone to custom grind a hydraulic roller version.

 

Talk to Mark, aka Cutlassefi.
