If you plan on building it and running it hard, then don't try using a stock 302 block. You'll split it open like a pineapple(seen in first hand).

If you have to buy an aftermarket block, you might as well go BIG. They make 427ci Windsors(351). Friend has one, very mild, pump gas, roller cam and makes 500+hp. Runs it in a shortbed dent side that goes 12.5's at the track on street tires and AOD.

As for EFI? What makes the difference which stroker? Friend runs 360ci (302 Dart block) with '89 Mustang computer and Motorsport extender. Goes 10.6's.
