New 318 roller cam setup

Small Block Chevy....... Those guys can buy Turbo Headers and just about everything else needed to build a Turbo set up at the local mini mart. Its just not fair!

LOL, ya no doubt, what else is new? OO, I blew a ... I'll just go to 7-11 and get it in the turd section..."

So, about those cams for factory roller motors...

Are the ones in the major vendor's catalogs compatible, or are they made to work in a non-factory roller motor?

Is the cam/ lifter setup in the late LA (mid 80s to early 90s) the same as the magnums?

I'd like to go a couple steps up the cam ladder in my 87 318, but I've never torn into a roller motor.

You need to purchase a few books starting with hot to rebuild and then hot to hot rod my small block MoPar as well as a MoPar engines book. Your questions are valid but are major league basic.
