Shag,
Here’s a possibility for your Mustang.
First trip to the track and the guy ran 7.30 in the 1/8th!
BTW, I can help make it happen… 
I have a .030 over GN block, brand new pistons, crank and rods (needing polished and sized), and a set of stock heads fresh from the machine shop
Special Deal this week only $350, worth the loss just to see you give pewter a good run
