Hi all from sunny down-under

Has anyone done or seen done the conversion mentioned above? I'm also keen to know if the the Pro-Jection is suitable for marine use?
If it turns-out to be a good prospect, I would do it as a winter project and accumulate parts when the opportunities present.
Thanks in advance, David.
 
Ayuh,.... That's an Automotive system,....

Where, 'n How are ya gonna mount the O2 sensor,..??

I ain't seen any Efi that's worth the Money, over a carb,....
 
The marine flavor of pro-jection runs in open loop all the time.

You should be able to tune it to a 4.3L...shouldn't be a lot of hassle.

Like Bondo, I don't think it is worth the effort to get rid of the carb....now multi-port is a different discussion.
