Can't believe I missed this one. ProJection by Holley. Excellent on driveability and simplicity, poor on fine tuning for max HP. Not enough sensors IMO. They used baro, MAP, throttle position and water temp. With the change in weather we have in FL. and the infinitely variable tuning, it could cause you to go mad. Worked like a charm just like the throttle body EFI on the late 80's Chevy trucks. Make reliable power. UBHSTRY - Is that what you ended up using??

Holley copied the late 80's GM unit right down to the guts of the ECM(they simply put it in a different housing with some adjusteable features the OEM didn't have). Very basic system, and fairly reliable I believe. Myself personally would opt for something better if I was going with fuel injection.

When they work, they work. Once they get worn, most I know would pay you to take em off there hands. They do get good milage with alot of top end kick when they work, and they are fairly simple compared to EFI.

Ferm, one of the best things I've purchased over the years was the Carb Shop sold a primary throttle shaft bushing kit, it came with new throttle blade screws, bronze bushings and a modified drill bit that reamed out the throttle bores. The kit had enough parts in it to do 20 carbs. No one in my area liked Q-Jets, so i took it upon myself to learn about them. HP books has a great book that explains a lot about what goes on in a Q-Jet and how to modify them. Every one was preaching Holley, but my Q-Jets worked just fine, never mind the fact that you can usually pick them up for $20

Yep, used the "FASST" EFI, simple, felxible, and rock solid
