The cam that I have is out of either a 91 305 out of a Z28 or a 96-98 vortec truck 305...

The stamping on the cam are 140 98R and 155 WB83

So far I've been searching th net for a few hours now and havent been able to come up with a single thing.

BTW it is a roller cam

Thanks

Measure the cam lobes for the lift with a mic or caliper and look in the tech articles for the cam guide for lobe lift specs.

If I had a set I would..
