Ford didn't go with 351W because of CAFE standards, not emissions standards. My 351W puts out less emissions than my wife's 91 v6 Probe. It's the same one that went into the 93 Lightning. The gas mileage isn't much worse than stock either, so I really can't understand why Ford was so whimpy.
If you put one in, it should be an EFI setup. It will run better, give you more power and gas mileage, and is easier to tune. Go with TFS heads, TFS 351 intake, 77mm MAF and 70mm TB. I have an Crane Compucam 2040 (E303), but you might want something with more lift. I went with E303 since I wanted to pass emissions.
I eat SS Camaros for snacks. I'd like to say that about Corvettes, but you know who drives them.
