Cam choice!

David Vizard, author of 30+ auto books & over 4000 magazine articles has some good advice:
[1] The right cam cost the same as the wrong cam
[2] Getting the LSA too wide will cost more tq than getting it too tight
[3] if you want a smoother idle you do NOT widen the LSA; you reduce duration
Why listen to DV? He dyno tested over 19000 cams. When I find someone who has tested more, then I will take their advice....
The 5500rpm limit is imposed by the Edel Perf intake, not the cam. Might actually be a tad less with a 360, like 5300-5400. It would be stupid to install a 6500 rpm cam in a 5500 rpm engine. Very easy to over-cam an engine. Then the nonsense of using a hi stall c'ter to 'fix' the too-big cam. You don't need a hi stall c'ter with a 5400 top end. This is a cruiser with economy as some importance.
DVs 128 rule calculates the LSA as 108 for a 360 with 2.02 int valves.
Isky has a perfect shelf grind, the 270 mega. 221 @ 050, 108 LSA.
