Look through the archives, you'll come up with applications using the
same ecm as the MAF F-body, but are speed density.  And, I believe the
later PFI cars are MAP.

Edelbrock uses the 7747 pickup ECM and fires the injectors in a 4+4
arrangement for their MAP PFI conversion.  There's a good possibility
that you'll need a custom prom when running larger 350 injectors on a
305.

Two sources that I know of, one is the list posted to DIY_EFI(it's in
the archives), and the other is to talk nicely to the GM parts guy. 
They can cross an ECM service number to see what else it fits.
