Appears to be from a Chevy 350 in a Volvo Penta marine application.

 

Dude what is the radiator looking thing on the front of the TBI?

That is weird looking

 

Apparently that is the computer on the front of the TBI. I think the fins help it dissapate heat.

 

anyone know what the system is they are using in newer marine applications? i would guess TPI? i bought a new boat V6 with carb last year. the increased cost to go EFI was like $1500 and gave 10 HP more. seems TBI would work OK in marine applications as power is linear with no shifting.MAYBE i could learn to tune that

 

That is pretty crazy looking setup though. Never heard of the computer being on the TBI that is weird.

 

GM was selling TBI systems to Mercury Marine at least as of a few years ago; do a search for MEFI and you'll find the threads (that involved dual TBI !). Now that they use Vortec engines, I think they've gone to CFI (central poppet-style FI) and gotten away from selling any new TBI (v6 and v8) engines.

I can't tell from the pix in the link if the intake manifold is a special high-rise for TBI, or, a high-rise carb manifold + TBI_adaptor + TBI. Probably carb manifold + adaptor.

The ECM case looks similar to the finned PCM weatherpak housing GM used on my old 94 LT1 Caprice... and I suppose air movement around the engine would help cool to the case. Still, why subject it to engine vibration if you don't have to. Interesting find.
