Thought I would ask a few silly questions since camshaft numbers have never been my strong suit. I selected a solid roller from Harolds list, this is going in a 540 with 9.6:1 allum merlins flowing about 370cfm IN and 270EX @.650, merlin single plane/holley 1000cfm/2.125 lemons headers. The cam is 255/263 .685/.680 its listed at 107 lsa and C/L IN 101. I asked them to grind it on a 110 LSA. Does any of these parameters change when spreading the lobes? And from these numbers does this cam have alot of overlap. Im hoping to make 9 or 10 in. of vacuum at idle. Any guesses on approx. power?, I hope I made a good cam choice.
Thanks Rich

There is linked in my sig instruction on how to calculate overlap.

Rich, have it ground on a 107LSA, it should ET better then the 110 with your compression/trap RPM's ect.

255/263 @ .050? w/ 107 LSA yields 45 degrees overlap at .050. Doubt you will see that much vaccum at idle.
