I agree that two single bbl TBIs could be used in place of a single 2-bbl. I may try this eventually. The easiest way to do this on a chevy is probably with a dual 4-bbl intake. With the aftermarket computer I'm using (Holley Commander 950), it can drive up to 4 TBI injectors.
Trueslayer, you'd probably have to fabricate some kind of setup to attach the kickdown cable to the TBIs. Although, this may not be too hard because the GM TBIs already have an attachment point for the TV cable used with the 4 speed autos.
bigchevy, I'm just using a stock HEI distributor, since the aftermarket computer doesn't require an electronic distributor. It can, however, utilize crank triggers, etc. if you want it to control the spark timing as well.
One other thing that is messy about the multi-port setup is the location of the cyl 3 & 4 injectors. There's not much room between the throttle body and the head!
Tom, there are times when I definitely agree with you, and that multi-carb setup looks great. However, for that cost you could go EFI. So then it's just a matter of which you're more comfortable with, and I'd rather tune EFI than that carb setup!
