FS Holley Pro- Jection 4
 

I have this listed in another ad but I want to add pictures and more info. This is an early Pro- Jection that does not use a laptop to tune. It is 900 cfm and the complete set up with the optional O2 sensor.I had it on my 79 Trans Am for 3 years without a problem. Turn the key and it would start right up and idle. No " setting the choke" or feathering the gas to keep it running. I have the RAIV cam with 1.65 rocker arms and could get it to idle as low as 500 rpms. Once I had it dialed in I did not have to touch it.I am asking $500 obo. This would be great on a driver or mildly modified car. You can call or text my cell 847-501-1019. Thanks Doug

$400 obo.

How can you distinguish from the CFM models or were all the PJ 4's 900? 4D * 4i" I see go to 650 & 900 CFM granted they are later editions.

Any tips for this system? I ask as I have it on an on going project and may use it another one (this one) on a future project as it is cheaper than a full muli port system. What did you do for shaker set up as it is shorter than a carb?

All with 4 injector style is rated at 900 CFM. Not the seller just trying to help out.

Yes, one of the older Holley carb book had some tips on this system. One tip was to use a Holley red pump by the tank and mount the fi pump up by the engine, so it wouldn't have to push so hard. I used two relays ( one for each pump) and used the fuel pump wire to turn them on. It also helps save the drivers in the unit. I have more tips but I feel those were the most helpfull for me. If you have more specific questions pm me. I'll be glad to help.I used spacers to get the correct height. Doug
