340 max camshaft with exhaust manifolds

Here 108 vs 112 vs 120, there was suppose to be 116 to but had some problem.

There almost no difference in peak power but about 10 tq between 108-112 and 30 tq between 112-120 so obviously 116 would about mid between 112-120 seems like the difference grows slightly by a few lbs-ft the wider the lsa, at least in this case.
