On a budget/ new short block?

My 86 Mustang has a 302 that currently runs 12.90@106.6 with ported 72 heads. I was wondering if I were to set up a 351 windsor with these heads and cam with a stealth intake and long tubes what I could expect for gains. I am on a limited budget so I need to reuse some of the existing parts. All thought and replies would be greatly appreciated. [img]/phpBB/images/smiles/icon_smile.gif[/img]

Mite ask this in the tech board. But i would work on the 351 over time and put all the right parts in it. The cam you have in the 02 wont act the same in the 51. More cubic inches tend to tame cams down.

I know the combo(302) It has a 351 windsor m-6250-a351 which may do fine with the extra cubes and small heads. He may even be able to degree the cam in a couple degrees late to help it along.
