Heavy Truck, if cool points are what you're after, then here is someone that's posting on this thread that can help you with that; even more than sequential EFI.
As I recall he's working on some aluminum 12 port goodness that would not only look cool, but should allow your 292 to give the V8 guys fits.
I just don't know how far along in the process he is (hope it's not a bad thing, me posting this).
Now, in all fairness, if you want coil on plug, and sequential injection, with 6 in a row, why not ditch the pushrods and go with a later model 4200?
DOHC, EFI, all aluminum, straight from the fiends at GM.
