Banger Fuel Injection

This sort of puts a model A in a street rod category since there was not much for fuel injection back in the traditional hot rod era.

It would be difficult if not impossible to set up a intake port EFI based on the OHV heads currently on the market for Model A or B engines.

Denis,
not really, this intake induction could be approached a couple different ways.
Knowing the CFM of the intake TB, you could size two injectors and place one on each end of the intake. But better due to crankshaft and port layout it would be better to have the injectors feeding at the TB.
The direct port injection that you are referring to is best, but as you say requires a 4 port (individual) port design. Such as the Price 4 port Cragar, Serr 8 port (near finished development) and a Riley 4 port head.
What Jeep is talking about is a TB with injectors in one unit, very similar to the older TBI done by GM, back in 80's?

A record was set at Bonneville with a std port arrangement flathead motor.
It had two injectors spraying in each of the ports very close to the block. It was fully sequential and was to allow tune for each of the cyls.
