I called Bullet racing cams today and they feel there is a mistake in the grind. They would like the cam to be a 242/256 114 lsa 626/608. (current cam 242/248 112 lsa 626/608)
They said the boost is going right out the exh due to the Lsa. I am a little annoyed as THEY spec'd it based on the combo and now I have a **** load of work in front of me to change it plus I have to buy another cam, or regrind, because of their mistake. I specifically asked about the LSA when I saw it and questioned it as I thought it was to tight. I was told the cam should be excellent for the combo and not to worry. They are willing to regrind the cam for $125 or purchase another @WD for $310
I am going to check all the things previously mentioned but the person at Bullet Racing said the cam is not optimal IE WRONG, for the combination.
Needless to say I am disappointed and a little steamed about this... I may call and speak to another company to see if they both say the same thing.
Any recommendations?

It may be water under the bridge... But the LSA doesn't matter in this case, as those two cams have the SAME 21° of overlap at .050". So the "boost going out the exhaust" explanation is nothing but ridiculous. However I could see more exhaust duration and an earlier EVO being beneficial for this combo.
