You'll need higher end heads for your goal, and the 4.125" bore block (an option) will also be handy. The higher end heads are what pushes the total from around 650hp to 750hp... and the cost from your $16k to $20k.
You might get close to 700hp with the 225's, but unless you are Joe Sherman, you will probably end up around 650.
Drag79stang made around 700hp with his AFR heads that were ported by Ed Curtis, and it did tickle high 8's once he hit it with the bottle. As was said, he has since sold the car. It was a tubbed, lightweight, drag-ONLY car.
How fast do you want to spend? THAT is the question.
If you live close to CA, you just might want to have your checkbook handy, and give Mr. Sherman a call.
