Need top end advice

Thank you for your info. So if I go solid roller , it will make that much more of a difference? What is a good SBM cam company you recommend?
Each step up in cam style, IE; HFT, SFT, HR, SR will make a little more power over the last. How much power is a loaded gun unanswerable question.

There is no one company better than the next for any engine and even more so for a SBM. That’s ridiculous on the highest level.
