Small Block Cam Info - Magnum Head Swap

I've come to realize that I can't actually map the lobes out with the advertised,
I told you how to do it
most everyone is .006 except Crane, Cam Dynamics, Summit and the white Boxes at .004 and at these durations scratch all off your list
Then the MP, Engle and Racer Brown at .008 and Isky just add 8 degrees you will be close
As for comp there is absolutely nothing shorter than ,275 that you should be interested in. The Purple Plus 280 is the smallest in that line and the Nostalga Plus is a similar design but dumbed down to make mfg less expensive- you loose torque compared to other cams with similar advertised durations on the list I posted
you can get the details in the comp lobe catalog which btw is much better than most

"ut I'd like to go with a cam with a tighter lobe centerline, at least a110"
LCA should be a result not an input
where do you want your intake to close at .006, how much overlap @.006 etc
I forget is your lift limitation valve stem seals or springs. ??
The MP cams, Engle and others that may fit your lift range and still provide a big fat lobe, like a shorter purple plus
do not get caught up in the marketing "my dick is bigger than your dick" sindrome
you might check out the 904 lists at Bullet and Camcraft, Engle

Forget agressive lobe profiles, and I consider the Comp XE line borderline agressive . more agressive than the Hughes, Lunati but since it is working on the smaller lifter that's hidden
I'd work on engine sims first, cams can drive you nuts, get the compression and rev range nailed down and the list of good working cams will narrow
let us know what you find
