Had cam doctored, need help deciphering printout
Had my cam doctored and got it back today with a printout with a hell of a lot more info than I really needed, lol. Curious if someone could help me figure out exactly what I have.

Would it be safe to say it is NOT a T-rex, which it was claimed to be when I purchased it. T-rex specs are 242/248 - .608/.612 - 110 lsa
I know each individual cam differs a little in it's exact specs, not sure what that margin is though.

cams are not always perfect, they may be a little larger or a little smaller than advertised based on what COMP, CRANE, ETC claim as acceptable through there QC process.

A member on here. Not gonna run his name through the mud because once I expressed my concerns about it, thus me getting it doctored, he was more than willing to refund my money if it ended up not being a T-rex. He was 100% positive it was though, so not sure what the deal is.

there should be numbers scribed into the front of the cam, post a picture or what they are and we can tell you what lobes they are suppose to be.
it could very well be a t-rex and it falls with in the QC tolerances.

no individual nubers like 1235HR 1356TK 110LSA????
Does anyone know if thunder uses Comp/crane/cam motion?
You can always call thunder to see if they can help you out.

IMO, 6 degrees larger than the advertised intake lobe, while falling .015n-.020 short on lift doesn't seem like the same cam.
