yea…I will stick with my opinion .
I know a guy that had a 440-450 ish inch MC deal in a 3000 pound car, roller cam, Yada, Yada, barely got in the 9’s, and it was well sorted out.
Ryan for years said that head wasn’t any good( even though the numbers suggested it was( 350 ish cfm)
I guess anything can be “ fixed”… but ultimately somebody will have a pile of money in such a deal.
