I have a question about something not addressed in your great paste from fast351.com: the firing order on a 351W is different (1-3-7-2-6-5-4-8) than a 302 (1-5-4-2-6-3-7-8). If you want to be carbureted, all you have to do motor-wise is swap the wires on the cap and voila! BIG question, though. Didn't FoMoCo change the firing order in later 351's? If so, to what?

HOWEVER, if you want to keep your sequential EFI setup, how does one match up the firing order to the injection pulse? You can still swap the firing order on the cap, and it will run, but it won't make NEARLY as much power as it could/should. It's easy to figure out why.

The fix, then, is a different ECM that will in the correct order "fire" the appropriate injector, right? I'm SURE there's an aftermarket conversion kit/package out there, isn't there? OR...what OEM ECM's would be compatible with whatever EEC module your Mustang happens to run? OR can you reprogram your existing computer to pulse the injectors in the right order?

This something that a swapper keeping EFI needs to know, 'cause I'm thinking of the same dang swap, but I want to iron out the sequential fuel injection issue before I put both feet in, because I want the drivability/tunability/power-making ability of EFI.

SOMEBODY'S got to be all over that, because it's just too easy otherwise - all those cubes, longer stroke, torque, thicker block webbings, stronger all around rotating assembly (on and on it goes!) and all you REALLY need is a wider lower intake, different headers (maybe) maybe a new oil pan, new accessory bracket (that's a new one to me) and a hood. C'mon, that's a cinch!
