It should physically fit the bolt pattern but you may need to match port the manifold to the head. It wont bolt directly up but it is very close and would only need to have the bolt holes opened up one size or elognated with a round file or rotary burr. Somebody here just bolted up a 931 manifold to a NA head with little trouble.

throttle bodies, not carbs.
that is the difference, shorter intake pulses raising the HP to a higher RPM and making more at the higher RPM, with EFI,
that is my guess anyways.

Carbs have fuel jets in them. Take the fuel jets out of a set of Webers and you have individual throttle bodies.

Rig up a TPS and feed them from a plenum, and it's Alphalicious.
