Sometimes I wish I wouldn't even look at this site. The BS in this thread is so deep I feel obligated to post.

Eric4Nitrous, please give some credit to those posting on this thread that have the cam you're talking about. They may not have $40k to have a builder make an engine for them, but they know what the heck they are talking about, and you sir, have no clue. Take your 6sec car and race it or sell if for all I care. Bottom line is I won't tolerate your bull on this thread. Do a little research and figure out how cams work. You don't even know how a camshaft works, obviously. Even the stock cam will pull to lower 5000rpm ranges when installed in a mildly modified 302. The manufacturer rated power ranges on both the E303 and the B303 extend to 5500rpm+. I don't know where you got your high horse from, but it's time to start letting Mr. Glidden answer your engine tech questions.

Mach 1 You seem overly concerned with LSA's again, but unlike your assistant in misinformation, you at least have a good idea of camshaft basics. As I have pointed out before, LSA's are only one part of camshaft overlap. A snapshot of the E303 looks like this.

.498/.498, 220/220@.050, 282/282, LSA 110, LCA 107/117

The B303

.480/.480, 224/224@.050, 284/284, LSA 112, LCA 109/119

What that all means? The E303 when installed straight up, is not actually straight up. It's built with a 3* advance on the intake to help control compression. It also has a less aggressive ramp rate than the B303, and less duration. That means the actual amount of overlap on the E303 is smaller than what you think. That's why the E303 is recommended for the AOD, and the B303 for the 5spd. The B303 has the makings of a more high winding cam than the E303, but doesn't have enough lift for an EFI car. The B303 will perform well on a carbed car, though. Not that it's BAD on EFI, just could use some more lift to make use of it's more aggressive duration.

The E303 is a solid supercharger cam. Both you can Eric might learn a little by checking out some of the site's combo's using the setup. Nicolle Douglas is making 500rwhp with an E303 and a supercharger. Dan McClain made 500rwhp with a supercharger and E303. Exgmguy has posted here about how his combination runs. Skyman's car peaks over 5000rpms as well. 88workcar has posted. What else do you skeptics need? I've given a technical analysis, as per standard, along with some explaination, and cited examples of people running the cams you're bashing. I fail to see how you have a leg to stand on. Not that you had one before with people who ACTUALLY run the cam telling you it works. Mach, I do believe you had the E303 in your auto at one point, and you were very frustrated by an idle problem common to the cam. Maybe you're harboring grudges for it robbing you of sleep?
