well im thinking the cam might be a tad to big so im feeling out all directions]
Since it's pretty much a foregone conclusion that your static compression is not going to work all that well with anything resembling a high-horspower cam, you can either change the cam, the pistons, or both, if you want to run anywhere down in the 11's (without putting your motor in a lighter chassis).
Add up the total cost (including gaskets, cam, valvetrain components, etc.) for this change, and when you get a viable total, see how it compares with the cost of a turbo setup that would NOT include pieces that you ALREADY HAVE ON/IN the motor, such as your existing, 4bbl intake manifold, your converter, rear end, pistons, rings, cam. valve springs, rockers, etc....
Doesn't leave much to buy, other than the exhaust manifold with a turbo flange welded to it, and the intake (cold) plumbing, a wastegate, and a blowoff valve, if you want one, along with changing your carb to blow-thru jetting, etc.
Tom Wolfe bolted a Buick turbo on his bone stock 225 '70 Dart with a 2bbl and went 12.95 @104.... You'll go a LOT faster than that.
You probably can do this cheaper than fixing the compression/cam issues of your normally aspirated motor.
Maybe not, but I'll bet it will be close...
I'll shut up, now.... :)
