Hey guys I was board today so I ripped apart a spare block I have and found a cam with some engravings. I proceeded to do a google search and came up empty handed. So I could use some help. Here it goes......

3313/3315 engraved with dremel
HR114+4 also with dremel
U5217-10 also with dremel
4615yn with factory engraving

Thanks for the help

 

Looks like Comp Extreme energy lobes
218/230 lift is .495/.510 with 1.5s

HR114+4 Probably means 114 LSA and 4degrees advance ground in

Really mild duration and lift, really big intake/exhaust split, ridiculously wide LSA which either means an ignorant emissions grind(112 would have been fine that mild) or maybe it was for boost.

Might be interesting to see what it would do with a turbo and some 1.6 rockers.

 

I dont really need it so I guess I'll put it up for sale

thank you

 

Large split and 114LSA might also indicate a nitrous cam.

 

Thanks fred I will include all this info in my for sale post thank you all for your help

 

That is a somewhat common Comp Cam blower cam. Xtreme Energy HR Lobes as Dwayne said: 218/230 .528/.544 [1.6] 114LSA 110ICL

Thunder Racing sells this cam as a blower camshaft.
