That first cam you tried looked like the mother of all motor home cams. Lol!
My fault, I entered the cam specs as seat-to-seat rather than @ .050. Pretty entertaining results though, lol.
It`s not too hard to make some big numbers when you start with a lot of cubic inches. I have a 496 based on a 440 and I love my stroker motor, there`s nothing like the feeling of those G`s planting your *** in the seat when you let `er loose. You will never go back once you`ve been there.
