B cam vs E cam

Oh God, this debate again....

j/k

The B cam is made for manual transmission equipped vehicles (hence its E.O. for stick cars ONLY), and the E for automatics. The reason? Simple: duration, as Mustanguy pointed out. Even though the B has less lift, the duration makes up for it on the top end by what I've seen.

It looks like you're running a C4 auto, so I'd go with the E unless you have some sort of unholy stall and gear combo. Here's an interesting situation, though: my buddy is running the E in his '89 GT but it's a stick. It runs pretty strong (like a cheetah on crack above 3000 revs), but lacks the low end grunt. That's probably not a fair evaluation since he has stock gears with a stock fuel system (and mostly other stock parts), not matching the 2.02-valved Windsors he has on there. Needless to say, once it's moving there's no stopping that 'Stang!

The idle of the E is still pretty sweet with just a little noticeable lope, but that highly depends on where you set the idle speed too. I'll be running the E cam with my setup this summer which includes 165 AFRs, Cobra intake, a Lentech valve body in the AOD, and various other goodies. The 3.73's should complement it ver well, hehehe. /me wipes evil grin off face
