OEM Cam specs for '95 Gen1 351?

Anybody know the numbers? My research says Intake is .416 lift @ 260 and Exhaust is .444 @ 274 with 1.6 rockers... Does that sound about right?

The stock cam specs are:

· Flat tappet

· Advertised duration: 260º intake, 274º exhaust

· Duration @ .050: 200º intake, 214º exhaust

· Gross Lift: .260" intake, .278" exhaust

· Net lift w/1.6 RR: .416" intake, .445" exhaust

· Net lift w/1.7 RR: .442" intake, .472" exhaust

You need to run a G5X2 cam like this one (http://www.svtgalleries.net/gallery/data/500/15YellowZ06.mpg)

Duration at @ .050 232/240
Lift at vlave .593/.609
LSA 112

I plan to run the OEM Lightning cam for now.... I wanted to change to a FRP Hydraulic Roller, but the techs at Ford Racing convinced me to stay with the OEM cam and just use a 1.7 rocker to bump the lift slightly... my current goal is only 400 rwhp, which should be pretty easy with the KB super charger and more than can easily be handled with my current wheel/tire/suspension/transmission set up... although chassis updates are on going, I feel a conservative hp goal with monster torque is the way to go for my application.

Thanks for the info, any more thoughts would be appreciated.

i thought they came with a hydraulic roller cam? or maybe some of them did, or maybe none. im very absent minded

Nope, they were all flat tappet. The later blocks were predrilled so you could convert to a roller.
