Rather than do a whole fuel injection swap out here in CA and have to revert every two years...

Might be a good solution; the price seems reasonable. It would likely increase HP given the accuracy of fuel injection vs. carburetion (as L-Jet does) and MPGs.

Wow, guess I have to rip all my home-made wiring harness on my X.

Joe, you need to install one as a favor to MIRA and report back.

I saw those and recognized most of them...

Now I just have to figure out how to have it delivered on a day my wife isn't home.

Rochester 2GC's were used on V8's from the earliest SBC 265 cu V8, to the 389 and 400 Pontiacs... .. and everything else including 3 X for the GTO tri power. Bore size either 1 7/16 or 1 11/16 , and venturi varied from 1 9/16, to 1 3/8 …. Going to discuss this with my engine guru /cylinder head builder ….

I would love to try this but I'd have to take the really cool Weber carb bumper sticker off my Spider.

Those venturi sizes (35mm+) seem pretty big for an 1800.
