Flat tappet vs. Roller 351
What are your thoughts on converting a 351W block to use roller cams? Suppose my goal is roughly 350hp street-driven and at least decently reliable from a 351W. (1) Can that level of performance (350hp) be achieved with a flat tappet setup? (2) If so, will the flat tappet be constantly requiring adjustment, or will it be decently reliable?
Trying to get a feel for whether the added expense of a roller conversion is worth it.
Edit: oh and while I'm at it, I'm told that for moderate power levels (like 350hp), the 2-bolt mains on the 351W block are just fine, no need for a 4-bolt conversion. This true? Thx
