I have a 2012 FLTRX, SE A/C SE race tuner, V&H HO Pipes and the V&H 2 into 1 into 2 headers. Was thinking of instaslling the Andrews 37h. Thoughts?

 

It'll work, but likes 9.8-10.0 cr to be truely effective.
You may want to consider an Andrews 48.

Correct me please, it would seem to me that the 48 would require more comp than a 37
I know it also depends on intake close which i didn't yet check, but usually higher duration the higher requirement of compression. Right or Wrong???

 

Want a great cam??? Go with Bob Wood's 555 or 575
You'll be happy!!!!!

 

In this case, you're wrong, Scott's right. You have been corrected! :-)

And yes, it's because of intake close.

 

Heck, just went to the Andrews page, the 48 has less duration than a 37 but more lift.
and quite a early closing intake. Kinda similar cam to the SE255's But a better choice than the SE
Makes perfect sense to me now!!!! Always look before you leap, or in this case speak!!!
