ok so i had ordered my cam from KRC, it was a 236x which is 236/242-555/575 112 LS. so i just got it from them but its a 236/242 520/540 112 LS according to the paper that came with the cam. can i still use this for a blown 408 at 16lbs? or should call and give em hell for not asking if i wanted to change specs? i'm kinda pissed TBH, but at this point i just dont feel like dealing with sending it back off, waiting on a refund, all that shit. :huh:
