<VV> Fw: Re: EFI Info Re: OBD-II for Corvair

[Mark Durham]

Timothy, Ray Sedman is helping me with my EFI project. He has a set of carb
tops that converts the carbs to throttle bodies. I happen to be boring my
carb bodies out to remove the venturi, which gives you 15 extra HP in and of
itself from increasing the available air, but Ray has CAD designed the tops
to accept the fuel injectors, so in essence you could just unbolt the old
throttle body, add his new top, and plumb in and add the other EFI stuff and
go. No mods to cylinder head or carb parts.
