'91 5.0 H.O. OEM Cam Specs!!!

[tjm73]

I finally found some meaningful OEM camshaft specs for our beloved 5.0. Figured I'd post this so people can have it for comparison. I found the info in a Car Craft article tucked in a picture caption.

'91 5.0 HO Cam:
208/212 duration @ .050
266/276 advertised duration @ .006
115.5 Centerline
.445" lift with 1.6 rockers (.278" at the lobe)

These cams are all over the place spec wise......i have seen anywhere from 260/260/206/206/444/444
all the way to 270/214/444

the only thing that remains constant, kinda.....is the lift.

and the lsa is all over too, from 112 for some, to 118 for others.....


who knows really.......

Duration @.050" is all over the place.I`ve heard this mentioned by a few who have measured different stock 5.0L roller cams,including a cam grinder whose name I can`t remember at the moment.

Crane Cams told me a while back that the 85-88 roller cams were [email protected]"[email protected]"
89-93 roller cams were [email protected]"[email protected]"

However every cam will not measure out exactly to these "official" specs.If you found two stock cams lying around and measured them,they are likely to each read different figures.

Sloppy quality control and cheap cam cores unfortunately.
