Hey guys, does anybody have any experience with these holley EFI kits? I am looking to make my truck a little more user friendly. I am planning to move back to CO within the next year, and have heard plenty of stuff about having to re-jet and tune the carb. I presently have the stock carter 1bbl. Have looked into going with a bigger carb with the offy intake and EFI exhaust, but the overall price is similar to going with an EFI kit, but I will have the same problems with tuning once I move. Any insight would be greatly appreciated. I found a good deal on a kit on ebay...check it out

Thanks for any help you can give me.

My truck info is in my signature, but just to make sure... I have an 86 f150 300 I6 with the carter 1bbl with all it's feedback glory

 

Great price on that kit, but you'll still need to buy the intake, so add that to your price. Also, IIRC this is a 900 cfm kit (overkill) and I don't think they control ignition timing (not sure, so check me on that). I'd think you might do better with a factory EFI from a junkyard along with some mods and programming. Still a great deal on this setup.

 

The devil with aftermarket EFI systems is the tuning - it takes several hours of logging data and tweaking to get it dialed in 100%. And you'll need a co-pilot to man the laptop while you're trying to log data.

I've got an older Projection 4-Di system I had on the 302 in my pickup. It ran fine, but I didn't have a laptop to fine tune the thing. Now that I've got a laptop I'm probably going to give it a go on the 300 in the Bronco just for shirts and giggles one of these days.

And like he ^ said you'll have to put on a new intake. Plus a TFI dizzy and the adapter if you want it to control the timing - and you do want it to control the timing. You've also got to plumb your gas tank for a return line or get an EFI tank and sending unit.
