What EFI setup are you running?
Wow, thanks for the write-up 1967'cuda. I was thinking about efi and was leaning towards FAST EZ EFI. They make it sound like all you have to do is plug it in. Should take just a few hours. It's good to see what it takes in the real world. I need to research this more now.
It would be possible to do an install in a few hours if you had everything you needed and didn't run into problems. If you ran a returnless fuel system with an inline pump would save time. It would also save a bunch of time if you weren't setting it up to control ignition timing. Of course if you just wanted to wire tie everything in place you would save a lot of time too.
One thing that I hadn't mentioned before was the need to drill a 2" diameter hole in the firewall for the wires to run through. We ran our hole very low (out of sight) on the passenger side below the heater box. And another thing I failed to mention is that we ended up having to replace the water pump housing because the original fitting for temperature was seized up and we couldn't get it out. We installed an aluminum housing that was slated for use in our Charger. One of the good things about swapping it out was that we gained a 'second' fitting location so that we could still run our factory water temperature gauge.
I'm sure that most folks interested in spending this much for a system are going to want the cleanest looking assembly they can get. That of course takes time. And with the odd lengths of wiring included with the harness, we had to lay everything out first to help decide where to mount the ECU. FAST really discourages you from doing any splicing.
I DO like this FAST system (not sure yet about their timing controls). But we didn't take any shortcuts on the install. - And we initially thought we'd have it all done in a half a day too.
But, we didn't know that their fuel pump was going to take a major modification to our tank. We didn't know we needed a phasable rotor. We didn't know we were going to have to replace the return line to the tank. We didn't know we were going to have to replace water pumps. We didn't know we were going to be limited on mounting location by the wiring. And to top it all off, my son decided to run all hoses in braided stainless AN. - And then he decided he wanted the ash tray modified to house the computer screen. If we'd been better prepared I'm sure it would have saved a lot of time.
The pics are of the '70 Roadrunner, the gas tank being modified, the wiring as it was started to be routed, and of the modified ash tray.
