I remember Dave Wren running a old Cam Dynamics R282 solid roller in his 1971 Cuda 383 SS car in SS/H I think, he let the clutch out around 8000 RPM and tried to shift it between 8600 to 8800 RPM shruggy
The original Racer Brown that owned that company back in the day probably designed and ground that camshaft for Mopar before they starting opening the doors to the lowest bidders in the early 1980s to the mid 1980s whiney
I also remember Joe Alread doing a series of articles on his Mopar sponsored 1972 Road Runner 400 stick car for either Hot Rod or Car Craft magazine in 1972, it had a solid lifter Racer Brown camshaft in it, I'm not sure which grind though blush
My message is there are a lot of better cam grinds to choose from today than back 30 yrs ago shruggy

Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
