.480/230 cam in an 8.5 CR 360?
iffin' you're gonna run that cam, i'd advance it as suggested. but as others have noted with that combo: low compression, blah stall, no gear and heavy car-- you've got a recipe for dog water. though, it'd probably run pretty good at highway speed.
there's nothing inherently wrong with that cam, but if you're looking to swap it i personally think that there's many other, more modern grinds out there that are much more suitable to the task at hand.
