If ya know ya are doing headwork and bigbore, pick a cam for the combo ya are planning. If ya aren't sure ya will do bigbore and headwork put 48s in.

 

a 37 with stock compression in a strre glide ??? is gone be really soft at low rpm i av a 57 same as 37 with more lift at 10 :1 in a 98 ci road king lot of tq but for a 88 ci i prefer 48

u can put a 48 for now and if u go bigger resale 48 and choose another cam for ur big bore at the right compression for the cam u choose
