Can someone tell me what cam came in the 93 Cobra, I'm building a 5.0 and I'm trying to duplicate the motor that came in the 93 Cobra, also did this motor use roller rockers? if so where the 1.6 or 1.7 thanks...

They ran the 1.7 rockers and had .480" valve lift, have no idea of duration or LSA (114-116 degs?)

It was definitely NOT the E303. It had it's own part number: F3ZE-6250-CA.

.480 lift (with 1.7 rockers), 270 advertised duration, and an LCA of 118.25. That's the specs I have on it.

WTF would you do that for? Those motors are weak, only reason trhey got good mileage was because of the gears.
