I have dealt with the speed-pro efi computer installed by BDS on a 351w that was probubly made for a SBC since that's how the injector harness was numbered. It has an O2, map, tpis, and water sensors. It was controlling a Kinsler individual runner intake. The tune-up put on it by BDS was terrible. Car made less power on the dyno than the holley 850 and victor jr that it replaced. I tried improving the tune, but only made a little headway in the drivability department. Car was sent to a "tuner" near sacramento who found more low end torque, but the overall drivability was still in the toilet.
I have replaced a holley pro-jection 1000 cfm that was on a 427 with a 1050 dominator. Car made lots more power, and drivability was unchanged. But the pro-jection is just a carb replacement, most of the benefits of FI are not incorporated since you are still sucking everything through a venturi and a carb style intake.(unless you're putting on a paxton or similar)

Just run a factory 302 setup, a mild hydraulic 302 is what it was made for.
