If your willing to change out the converter for more stall, you could step up well with a cam. Then it's just a milling of the heads for some compresion (On a stock engine) and if you can, head prep.

3.23's will limit the cam size a bit. Theres no big torque release or little I should say that will let a larger (2 steps up) cam work well.
You'll have a screaming top end, but nothing down low.
