Re: Magnum camshaft specifications
After reviewing my notes, I would add .075" valve lift. Base on stock valve lift of .425"-.430 (as measure when I torn the engine down), then the modified valve lift would be .500" lift (with room to spare). All of these measurements was performed using stock pistons and head gaskets.
Best thing to do is to measure you engine to be sure what the maximum the valve can open (with the piston at TDC) just in case there was some machining performed in the past.
