Slant gets a Sniper EFI by the numbers.....

Holley makes a BBD version of the Sniper throttle body if you can find a Super 6 manifold. They also make a drop in, in tank fuel pump with built in regulator.

Probably talking $1800 for the kit, pump, filter and misc hardware plus the cost of a Super 6 manifold. I'm not sure the juice is worth the squeeze for a car but I can see it for something like a generator that you don't want to be screwing with at 2am in the snow.
