I will try and answer your questions,
1. yes both of them are F&B systems on stock Mopar 6 pack intakes that were modified to take injectors and fuel rails.
2. I have no idea how much they flow, I would think F&B could tell you that.
3. On the BB, they are stock 906 heads (I believe), on the SB they are Edelbrock RPM
4. no porting was done on either engine or intake
5. Controllers
A. on the SB I am ruining a FAST EZ 1.0 system; I bought it when EFI was just starting to become a reality for older cars and had it for probably 8 years before I installed it. It only controls the fuel, so timing is same as always.
B. on the BB I am using a Holley HP system with hall effect distributor, so it controls spark and fuel.
I actually had the FAST system way before the Holley system but installed the Holley system a year before I did the FAST. That said, I can say that I probably prefer the Holley system as it gives you so much control over everything and you do it all on a laptop. Yes there is a learning curve, but it is not near as bad as some would have you believe, plus everyday there is more and more information being posted online and youtube.
I did think about doing a system using the Indy Mod-man intake, I liked the concept but in the end I just purchased what F&B had. I did have at one time a Rat Roster 6 pack Weiand intake but gave it to a buddy of mine, interesting set up and I am sure it makes power but more for a drag car than street car IMO.
