Forged or Cast? That's really the only thing you need to know. A set of calipers to measure the main and rod journals, and it is almost 100% likely to be a six bolt setup for the flywheel. Not sure on number. I'll look it up some.
I hope you are too
Edit: I just remembered it's for a 360 so if stock it will be a cast unbalanced.
I have an NP435 4 spd manual, 36 or 37" tires, thorley headers, holley 600, and i'd like to order it from summit so i get a little rebate. Right now i'm looking at the Crane cams truck power but I really don't know anything about it other then that it says its good from idle to 4,500 rpm. If i could get the same thing in the mopar purple i'd buy it right now.
Dumb question maybe, but do you know that you need a special balanced flywheel for that 360?
Just curious. If you have a stock balanced 360 flywheel, that would be great.
I have one in my storage room. The casted numbers are: 85276 and 2843212. It's from a 1978 360 hookup.
Not too savvy on cams myself, but there are lots of people who will read this thread and help you out.
With a edelbrock performer and 600 carb i would stay with a torquey RV cam. You will make more power with a cast iron 4 bbl intake or any of the other aftermarket manifolds then with a Performer. A cam i like is a MP cam with .430/.450 lift and 260/268 duration. One step bigger then that would work too since you have a manual transmission. Another choice would be a Hughes cam. Pretty much most of the other manufacturers use Chevy lobes on a Chrysler stick and your not taking advantage of the larger lifters.
