318 and boost...

I was just thinking the same thing about doing a single turbo 318 build, I was given a dart with a for 9 inch setup with a built 727, my thoughts were just to learn how do the fabrication myself and do a stock rebuild on the motor with some 2.02 360 heads and an airgap intake and cam, i can also get a blow through carb from a buddy for cheap. Not sure if it would be cheaper after buying the turbo and all the necessary accessories to get some decent power, or will it end up costing more than building a 400 horse 318?
