New block, a further discussion

[Fordors]

Uh, oh. Moving the lifter angles sounds like you are copying the big block Chevy method of enhancing flow.
Seriously though, that comes with other changes. The right bank will now open the intakes early and the left will be late unless cam timing is corrected on the lobes.
I am really an OHV guy, never built a flathead but here's something that I have thought about before. Say a guy finds an original Winfield SU-1A for an early f/h and he uses an adapter to run it with his 8BA block and ignition system. Does anybody check the difference in camshaft events and is it enough to matter? If I check cam timing events on no. 1 and then check no. 6 won't I see them different because the lifter angle was changed in the later block, or "rotated up" as Andy put it? Or am I just looking at that all wrong?
