so i am pretty screwed at this point. oh and my name is Zareh if TR sees my post.*EDIT* IT WAS ALL A MISUNDERSTANDING, Shane cleared it up for me. due to the fact that XFI lobes will grow approximately 2 degrees when cut on the LS1 core

I'm not 100% sure of the situation, but I do know that if the lift is only off .001, chances are you have the correct cam. Custom cams are ordered by lobe number, and we match each custom cam with it's order by serial number when they arrive. Certain lobe families "grow" when cut on an LS1 cam cores. Also, cam grinding (esp custom grinds) are going to have a certain margin of error that is considered acceptable.
When I get to the shop tomorrow, we will be happy to verify your lobe numbers and specs. You can also call and ask for Shane and I will get him to double check the specs and he can tell you for-sure if the cam is correct. The specs that you posted are consistent with it being the correct cam. (+2 deg on int & exh.)
I will definitely help you get this straight tomorrow!
Thanks,
Angie

I am actually the person whom Gene approached regarding your cam specs. I've worked with Patrick Guerra for years ordering custom cams and I am very familiar with his process. The 226/232 duration numbers are what your cam would actually read if run on the Cam Pro Plus. This is due to the fact that XFI lobes will grow approximately 2 degrees when cut on the LS1 core. The cam you requested is very similar to many I have cut in the past for Patrick's customers so I recoginzed the lobes right away based on lift and duration. The reason Patrick started quoting cams like this is because customers would be upset once they got their 224/230 cam with a Cam Pro Plus sheet showing 226/232! The correct lobe numbers for your cam are 3015R/3036R. If I were to run your cam on the CPP, it would generally read as a 226/232. If you would like to ship it back to me for this process, I would be more than happy to spin the cam up and check it for you.

hello Shane thank you for the response, i called and talked to Angie today and she explained the same but recommended i talk to you as well. i now understand what you mean by the lobe #'s thanks for the offer to run it on the CPP, unfortunately i need to give the cam asap to the mechanic. but since you explained it to me now i understand it much better and you guys know for a fact that this is correct, i believe you guys. As long as the duration is correct im happy. i already talked to Angie about the cam card since it wasent in the box, she said she will contact comp cams on Monday and email it to me. again i appreciate your help Shane, and say thanks to Angie, Gene and John for me as well. i am sorry for the misunderstanding, has there also been other people that have called about the same misunderstanding as me? or am i the only one lol.
Thanks for the understanding.
Shane
