I've been reading about the new systems that replace the factory carbs. Holley and several other firms make them. I have yet to find a bad report. Has anyone had personal experience ?..Thoughts ???...

 

Didn't you ask this same question ~6 months ago?:

I feel like everything was answered properly, it was a good discussion too

 

I've got a bad report on Holley ProJection, but it needs to be taken with a grain of salt.

I had a ProJection on my Bronco. The project timeline and priorities got kind of fluid (I'm sure that's never happened to anyone else...) so it ended up sitting in the box for a few years before I put it on the engine, and then on the engine for another year or so before I fired it up.

Once I got it running I found it had a horrible dead spot. During relatively hard acceleration somewhere around 2500 rpm the fuel would shut off. It was pretty annoying with an automatic trans, but when I switched back to a manual it would chirp the tires from compression braking when it shut off, and then chirp them again when it came back on.

I decided to go back to a 2bbl Autolite on a stock manifold. And my gas mileage went up from 10-11 with the ProJection to ~13 with the carb. I still have the ProJection sitting on a shelf, but doubt I'll ever use it.

The grain of salt is that I never gave Holley a chance to help me debug it. Maybe if I'd worked with them I'd have ended up getting it working great and would have been happy with it. But I'm happy with what I've got now.

 

Maybe ozark1 would be interested in your unit?
