Please don't beat me up too badly as I'm a newbie when it comes to Mopars. I want to install a port EFI unit on my stock 383 engine but everything that I've seen is for the RB type engines. Is there a means to adapt an RB port injection unit to my 383 block? I'm thinking that I'll be stuck with a throttle body of some type. Please help!!
I don't see anything for the low deck "B" block. I though Indy might have a ModMan, but looks like they are made for the RB engine.
Indy does sell a EFI "kit" 400-F4-31 Link:

I think it is a modified 400-I4-2 intake modified with injector bungs?
It looks like you will have to pick a manifold (single plane) and install the fuel injector bungs.
I think the small pads on most of the intakes are just for nitrous oxide injectors.
You can get FI bungs that weld or screw into the intake, but the fuel rail will have to have the same spacing as the bungs.
As noted by 1 wild R/T, call Fastman EFI for an intake like in the photo.
For the cost, the TBI EFI units (Sniper / Fi-Tech) are pretty good and alot easier to wire.
The Fi-Tech came to market a year or two before the Sniper and I have the Go-EFI 8 1200 PA unit.
I wanted the timing control, and only some of the Fi-Tech have timing control. I think all the Sniper units come with timing control.
It seems that Fi-Tech wanted to "dumb down" the software to make it "easier", and they sort of have their own nomenclature that is a bit different than most EFI systems. So far the EFI unit seems pretty good, but I had a problem with their Hy-Fuel in-tank pump not having the correct submersible fuel line.
I like that this works with a factory lean-burn distributor on my 500" (499) stroked 400 block.
For a comparable price, the Sniper seems to offer more, and uses conventional EFI terminology.
I installed an entire Sniper system on Mikes 496" stroked 383. That was the Sniper fuel tank (Tanks Inc Tank and pump assembly), the TBI unit, and the HyperSpark Distributor and CD Box. It all seems to be working fine, but just got it done a few months ago, so not that many miles on it.
