True. Some may call it dumb. I would not give a care. I’d like to build a 500 B engine and use a TQ on a M1 single for laughs.
But the real trick in this and your idea of a build is max house displacement coupled with great flowing heads that will very much extend the rpm range of the smaller cam.
As a exaggerated example, using my B 500 above, using a set of TF heads and a mild solid flat tappet cam custom cut that is something like 240-248 @050, with a lift at the valve of .600+ seems like a small cam ready to perform up to 5500-6000, but the awesome heads and big lift allow more rpm out of the set up than normally experienced. Not that I’d have any delusion of 7K gear shifts! LOL! But I think I “could” yank another 500 rpm or so out of the normal range of the cam on what is regularly seen.
