Alright well this tuesday I will be getting my engine block. My current 350 is in great condition, but im building a motor to handle a 200 shot on top of 350-400 na. I want to pop a cam in my current motor right now, to hold off my power needs, but Im curious as to what is the largest one I can fit with my stock l98 heads? I will get better springs and rockers, but I dont want to waste time on my l98 heads and porting and decking them to make a bigger cam fit.
