Hey, I've done a search and couldn't find what I was looking for. Does anyone know the specs on the stock 2.8 cam? Also, IIRC it is a flat tappett cam, right? That would make it unsuitable for roller lifters? Thanks in advance!

I don't have the full specs, however, the lift on the intake side is 0.231 and on the exhaust it's 0.263.
