[Sold] Holley Projection 4Di fuel injection, 350-500 HP

<<<SOLD!>>>

Practically new with only 200 miles of use. I purchased new and it has been stored in the original box for 10 years. Bolts to any square bore carb flange. 900 CFM 4-barrel throttle body supports engines up to 500 Hp. I highly recommend that your engine makes at least 350 Hp to operate properly.

Complete system from fuel pump to ECM. All you need to do is install a new O2 sensor (mine was cross-threaded but is included with the kit) and have a computer with an older version of Windows and 3-1/2 inch floppy drive (my computer had Windows ME). System uses standard GM sensors available at any auto parts store and is easily serviceable.

This is a rare opportunity to own a nearly new-in-the-box programmable closed loop fuel injection system for less cost than a carburetor!

$450 shipped. If shipping cost exceeds $50 then you pay the extra cost.

Are you located in the Netherlands? I'm not shipping outside the US. Too much hassle.

Here's a picture of the tag I pulled the part number from. It can also control spark timing if coupled with a GM 7-wire distributor, or you can just use any stand-alone distributor like HEI or older style that does its own thing.

Thanks.

Still for sale. Added little bonus that people know where to go if they want spare parts.
