Yup, I fat fingered that so I fixed it.
As for overlap, and BTW Howards used a .904 lobe for that cam which is good but their cam with its LSA has 87 degrees of overlap. That is seat to seat overlap.
I went to the Howards lobe list and found a 270 and a 286 lobe that are .904 lobes so that's an equal point and those big exhaust numbers still get you only 88 degrees of overlap.
That's because the went to a 109 LSA to keep the engine from drowning in overlap.
Very interesting I think.
