Take a look at the link I posted earlier and read the articles Buddy wrote. Cam truth is a good one.
I have heard and seen these cams go either way. Sure they make more power than stock but almost anything would.
So spending $150 dollars more on a cam is expensive? I have seen people blow money on worse $hit for their cars that do not do anything.
Do you have proof that they last longer than a custom?
Again, is $150 worth 10hp? I think so. Also better drivability, idle, power through the rpm range... the list goes on.

Now you can take a look at my posts on cams.
#1 The stock cam is a GOOD cam. Don't know why it's so hard for people to comprehend that. In head to head comparisons, the F303 in particular does great. Any cam can screw a combo, and I've seen people post where the cam they were recommended turned out to be a POS for them. If the combo is setup right, ie selecting the right cam for the combo, it's going to make good power.
#2 Spending $150 more on a cam to get the exact same result or worse is expensive. I'm not in the habit of blowing money, period.
#3 I don't have to prove they last longer than custom. I never said custom cams wouldn't last, just that the alpha cams have the history behind them to prove they do.
#4 Better drivability. How? Explain this to me. The F303 has good LSA, maintains vacuum, has a nice, solid duration, good lift that can be used in combo with any decent springs and it makes the same power in tests as most of the aftermarket high dollar cams, and I've never seen a heads up comparison where it's down more than 5rwhp or so. It makes good midrange, keeps the lowend alive, and the top end is solid as well. I'm not saying that there are not better cams out there. I'm saying that the alphabet cams get a bad rap because numb nutz the cam wiz kid throws the X cam into a stock speed density 87GT and then can't get it to work so he jumps on the alphabet cam hating wagon.
The E303 is known to have some vacuum issues on occation and mysterious idle surge. The B303 just isn't a whole lot of good below 3000rpm because of the overlap.
[b]Mach 1[b/], The E303 does have more LSA than the B303 110 vs 112, and it's better with the LCA at 107/117 vs the B303's 109/119, but you forgot to include the fact the B303 has 4* more duration. So while off center the E303 has roughly 1* per side more overlap as far as LSA and LCA are concerned, it gives up 2* per side with the extra duration. End result? The B303 cam has more overlap than the E303.
