Cam profile?? Can anyone help... I took my cam in to get profiled, becuase I wasn't really happy with the cam card sent with it, written in ink, on a 5 x 7 note card.
The Specs I was quoted was 218/228 550/550 on a 114 LSA.
According to this IF i am reading it right, the specs are 234/226 546/552 on a 114 LSA????
So here are the specs

THANK you for responding.
So what do you think it would perform like. Its ALOT different than the hot cam... but its about the lift I was looking for... Reverse splits can produce decent power...

Unless you have a really good exhaust and possibly ported/aftermarket heads the discrepancy in your exhaust duration could hurt your numbers. Only one way to find out... lol
