Ok guy I pulled the cam out of a longblock that I purchased that had a set of beehives and Texas speed pushrods. The cam was supposedly a 228r but doesn't have any markings on the back like a Texas speed camshaft. It only has these numbers on the front " 274.A 274.A LC or LG 20738 "

 

LG might stand for Lou Giglioti from LGM. I looked up in Comp cam catalog and XER has 273 at .006 and 275 at .006 but no 274 (which is possible it could be either 224/224 or 228/228.
Call LGM see if it is one of their cams.

 

anything on the back of the cam? that's where comp put's their serial #'s

 

I called LG and they said if it doesn't have a G5x series etched on it it's not there grind. I dropped it off at a local machine shop that has a cam doctor that will tell me the full specs and print out a cam card but I still won't know who ground it b

 

Well I got the specs on the cam but still don't know who ground it. Anyways the specs are 224/228 .575/.578 114

 

You mean "The Cam Doctor" could'nt tell who ground it ? Of all the nerve .,,,,Lol sorry, I just could'nt stop Myself.
