I'd say we're mostly carburetor dinosaurs here.......but you never know...

I haven't yet but there are many companies that make throttle body EFI that are the same dimensions as your carb.

Fast, Edelbrock, MSD, Holley.

So basically if your shaker fits now it will fit with their kits.

I run a Holley projection that fits. Actually have a 1" spacer and an RPM intake too. Its all coming off this winter for a new multiport system.

I would think a throttle body on a Torker II/EFI intake(Called the Victor EFI?) would fit and since TB are shorter than many carbs may need a spacer to get the Shaker up.

Victor EFI and Super victor will work. Super victor (single plane) needs the top to be milled down a bit though. Also depends on height of throttle body

Visit a local Pick A Part.
Chevy and GMC Pick PU's have these air cleaner spacers.

I installed the powerjection III last year on my poncho.

Air cleaner spacers will work but adding plenum voulme is not a bad thing with a spacer under the TB either. Most factory EFIs have a decent sized plenum.

Have this setup with Shaker in factory position on Eldelbrock Performer manifold using spread-bore to Holley square-bore adapter w 1" spacer on Pontiac W72 400.
