it's going to be pretty bad, even with the 2.00 journal. small base circle cams are made but you need to be careful with the lifters at that point

Thanks for the help man!!
Any thoughts on the cam i listed above?It was in a warhawk 427ci combo but thinkin about using it for this combo if i dont need a small base circle cam.
Im guessing im gonna need to have this rotating *** balanced again after clearancing rods for cam?Or maybe it will jst be a cpl grams id be losing?

I have the good lifters with tie bar.Brand is escaping my head rite now!lol
