I haven't seen anything (hacked or commercial) for the 3.4V6 SFI Camaro
PCM, but that would be pretty cool...
If I were to go with MPFI on a V6/60 like the 3.4, I'd strongly consider
the 1227730 ECM running $A1 code (3.1V6 MPFI VIN 'T', as in the '91-'94
Cavalier Z24). It's hacked, reasonably supported, and very tunable.
You might try poking around 60degreeV6.com as an additional reference.

1984 Chevrolet S-10 Blazer Sport, 2.8V6 (TBI pending)
