360 build

Which ede camshaft? .420 lift or the .488/.510 lift cam?

The bigger cam has quite a bit of duration at .050. If you have power brakes you may want to look at a different, smaller, camshaft.

You don't mention a stall converter. If limited to stock, that big ede camshaft will be a HUGE dog down low. I'd suggest at least a 3000 stall with the larger camshaft. When you start getting over 230* at .050 lift, stall convertors become a necessity on stock stroke 360's.

my 2 cents... :)
