I put a lunati voodoo 60303 cam in my low-cr 76 440. It did okay with a 3.55 gear but it definitely needed more than a stock converter. And that cam is only 224/230 @ 050 versus that RPM cam which is more like 240 and really designed for 10:1 compression when used with the eddy heads, 9:1 compression at a bare minimum. Now if you run a 3000rpm converter and 4.10 gears, you can get away with more but I still wouldn't run that performer rpm cam.
