i thought members would certainly benefit from this information....LSR cams are modern, aggressive cam lobe profiles - more aggressive than the XFI cams. They also have a new double spring specifically for these cams. duration split is crazy on some of these.... enjoy!!

54-455-11 215/223 .604/.610 112LSA

 

attached is a full list of cam specs... For most/all LSx lobes.

 

Some hellacious lobes there. I like em.

LoL Damn, you got it figured out!

 

nice grinds, but looks like most grinds are meant to be used with aftermarket/worked heads to take advantage of it...
