4bbl EFI is easy now. 3x2 EFI is a little less available and certainly more expensive, but in the case of my 440 and her 421, they both have 3x2 induction and that is how it always will be as long as we have them.
After investing $1k parts and labor with Promax in my 3 Holley carbs, with bad results (so far-I have to make the time to work on them, they are "as shipped" with some tuning on my part) I have to work with the Holleys for now, and give Dick B a shot at the Rochesters.
Not taking anything away from my expectations of what Dick B can do, and knowing that guys have had great results with Promax modded Holley carbs, that is what I hope for, but if EFI is the ultimate route for either or both cars, I hope that Holley's patent on a 3x2 Sniper EFI system will be a product available to buy by the time my decision has to be made, and I hope to hear of an additional alternative to the $6k-$8k all in system for the Pontiac.
