Harley, before you get your hopes up... Be sure exactly what you are getting.

Holley made / makes a number of ProJection units.

The original ProJection 4 is a 700 cfm 4 bbl ANALOG unit. This is the one that Fred has. It has a box with 4 dials to adjust the mixture. No sensors, no PC tuning, no idle speed control, nuttin. 1 step above an old rochester constant flow unit.

Then there is the ProJection 4DI. The D stands for digital. It has a computer very soimilar to a modern commander 950, a full set of sensors, idle air control, pc tuning, the works. The only thing it won't do is run a wideband. It's available at 700 or 900 cfm. I've had one, itsa nice system.

There is also a ProJection (plain ole, nuttin behind it) This is a 670 cfm 2 bbl unit. There are several different part numbers, car and marine applications, one is just the throttle body, made for upgrading the stock tbi on pickups and such.

Finally there is the commander 950 TBI, the current system. This uses the exact same controller as the multiport and stealth systems, and supports wideband and stuff. This is the one I'll be putting on this winter.

You need to get the part number and look it up at holley and see what it is and what it should include. Then you need to get with the guy that is selling it and see what's there.

I did a lot of shopping when I was searching out my current system. There are a lot of 2 bbl throttle body's going cheap on ebay all the time, and sometimes you see a 4 bbl tbi without the harness and computer, or a pro4. Digital systems are few and far between, and complete ones get bid up over $500 pretty quickly, and sometime close for double that.

Even if it is a bare 4bbl throttle body, the controller and harness is a grand, and that doesn't include the sensors and fuel pump.

There's a sticky here with pics of a 4BBL tbi for a digital system.

Good luck, I hope it comes up roses.

No brainer , good find

Jim's close. My Projection4 is "up to" 900cfm. (What does UP TO mean?) and the four TBI injectors flow "up to 80lbs and hour". (What does UP TO mean?) The most important thing that I learned on the dyno last fall was this system is too small. Oh, it's the very first analog system that Holley made. My son's getting it for his new 496 fire-up this spring. And firing-up that beast is all it's good for. Here's a look;

Mine is a Holley Projection 2D System. Came with the pump and everything that was on the Holley parts list.

Should be great for my car.....
