Budget 302 (I mean budget)

[BLOCKER]

Here is the dealy-o

I can get a 1991 Mustang coupe for lerteraly pennies (4 cyn not running needs tranny). And I do not have a lot of coin to invest. However I was thinking, for a lark, dropping in a 302 and tranny. Keeping in mind I already have the 5.0 susp. laying around (it is the old one out of my GT but is in great shape) Here is my proposition. I want a cheep 302 that I could build using ford orginal parts that could be found in your local junk yard. Keeping in mind junkyards know about old boss heads (from 60-70s) and those types of performance parts from the heyday of muscle cars.

What is the best parts from any year ford to use for my budget (and I mean budget) build up.

any ideas?
cams, heads, intake, carb.... what ever

p.s. this will be a carbuerated engine as they are cheeper and eaiser then EFI
