Bottom end info?

Agreed on the ratio. Your list of 11 to 12 - 1 ratio is way high for any pump gas.
A moder cam is the way to go.
Porting the heads would only take a pocket porting. Gasket matching a plus.
Decide on the induction system you want. It's a personal thing. Sexy/expensive six-pak or ave. everyday 4bbl is up to you.
Ignition. From what I have found experimenting over the last few months, I can only recomend as a bottom base line and nothing less to start with, none other than a Chrysler Chrome box and upgraded coil. Over at 4secondsflat.com, you can speak to Don and get his set up. It is a little better than the Chrysler box, bolts/plugs in no problem. His box has a advantage over the Chrysler box in mileage. Others swear by a power gain as well. I have not track tested it.
