hi just wanted to know if anyone has a roller cam in the 351 that passes inspection... i would like to put a cam in but i also wanna pass inspection... any help would be great thanks
Pass inspection where? I am in Portland Oregon and the only inspection we have is DEQ. As long as your emissions are per specs, you are fine. I don't know about other places. Let us know where you are trying to pass and someone from there should chime in.
I am not sure when they started, but the later 5.8's had roller cams from the factory. I know my 95 does. They might have started around 93 or 94. I am not sure though if they were different in certain states though. I am in Michigan.

What you need is an SD friendly roller cam, these have specs of less than 216deg duration @0.050" intake, 220deg@0.050" exhaust and an LSA of 114deg and greater. The Crane cam I have meets these specs but it's a flat tappet cam.. and it does pass emissions sniffer tests. Here are some roller cams... http://www.flickr.com/photos/motorstuff/1592206021/sizes/o/in/set-72157603881141642/
