Goose,love that as nick name... That's a really cool car and looks like alot of fun. I've got to ask, what was involved in to the efi conversion? as that has really peaked my interest Cheers! Yeah the car has been great fun so far and I have some mega road trips planned for it soon too! The EFI conversation was pretty straightforward for this as Holley make an almost 'bolt on' kit. Basically they provide a throttle body that looks like a carb, with built in injectors, throttle position sensor, air intake temp sensor and a built in fuel pressure regulator. So all you need to do is hook up an engine temp sensor, plumb in a high pressure fuel system and return line to the tank, fit an O2 sensor in the exhaust and hook up about 3 or 4 wires. Then the idea is that it self tunes after you input some basic engine information to the ECU through a small 3 inch touchscreen. It worked surprisingly well, especially as it's not meant to fit my engine. I made up an adapter to step it down from the 2 barrel Holley to my 1 barrel intake. So it's massively oversized for my engine application, but still works. They have now released a smaller 1 barrel version which would have been a straight bolt on... But that didn't exist when I bought mine haha What engine are you thinking on hooking it up to? |

Thinking about fitting efi to my fairlane in the future everything but the exhaust sensor sounds easy enough. Mines a very and the exhausts are separate the entire way, but I'm sure there'll be a work around |

@ebejeebies the O2 sensor install is also made as simple as possible.
They provide a plat with a bung in it with a nice gasket and some clamps, so you can just drill a hole and clamp it on if you don't want to weld it.
I had done everything to fit the kit up, got all excited to start it, realised the sensor was still in the box and I hadn't fitted it yet, 5 mins with a drill and it was on there!
Should be a nice easy install on the Fairlane!

So after some tinkering it was time to actually stick some miles on the old girl. A trip to Pendine from Buckinghamshire seemed a good one to start with, just a tad over 450 mile round trip to the Welsh coast. Gearbox still isn't fixed, but it seemed happy enough shifting manually so worth a go! Happy to report all went very well indeed and it was an absolutely mega weekend, the wife joined me and after 10+ hours in the Maverick she is eager to jump in for more road trips which is epic. We avoided all motorways and stuck to the back roads, it's pretty obvious this thing now needs the front suspension overhauled and i'm going to be investing in a disc brake conversion this year. Other than that, it ran almost faultlessly and not a single unplanned stop was made. Absolutely buzzing! There's a few photos I need to stick up at some point, but for now i'll just leave this here:  |

Excellent. Glad the wife enjoyed it too, it helps!

If you think about it Goose is doing exactly what he was designed to do, take a family to a destination and back. The difference is, and what is sorely missed by cars of today, is that the journey is part of the destination. Probably why I have fallen out of love with “modern” cars and love things that actually have a character and need to be driven. Great to see you racking up the miles, v8 and manual for the winter project then…. P.  |

The journey is certainly all part of it!
I was planning on building up a 302 I have to go in it, but the little 6 is currently winning me over.
Certainly in no rush to pull the engine just yet, the box does need some love though.
New front suspension bits on the way, nothing fancy just factory replacements which should be here next week to fit up.
I've got some 68 Mustang spindles that I will look to use for the disc brake conversion, once the front is done (will likely also swap to 5 stud) I'll look at getting the rear axle rebuilt with an LSD and new 5 stud shafts I think.

Its a cool car and the 6 adds to that, for me.
I believe there is a much better flowing Australian made head for that engine ( with a removable intake manifold ), that would be a nice upgrade.
That could be worth looking into...

That could be worth looking into... It certainly does exist, although i'm not after big power from it, if anything I may downgrade the Holley Sniper I have on it for the smaller 1 barrel version which didn't exist when I bought my 2 barrel and adapted it. Currently it keeps fouling the plugs up as i'm running on the most extreme duty cycle I possibly can and it is still too much fuel for this car. Not sure if you can purchase just the 1 barrel body from Holley and just pop it on there. If it works out be be a few hundred quid but it will make it a bit cleaner and not knacker the engine then i'll likely do it. Might mean I can also put my original air cleaner on there again too, the thought of that does excite me a little as it is a great looking piece. |

Or just add a turbo/blower to mop up that pesky extra fuel.... Always happy to help. P. |

haha now that would be sweet!
I think a power adder on there would be all show and no go though haha
I'll pull all the plugs tomorrow and see how bad it looks, might put the 302 on the engine stand too... Just to see how that makes me feel and get the mind working on what the way forwards should be.
Cleaning the plugs up every 500 miles for the next couple years wouldn't be the worst thing to deal with though, as long as it doesn't start washing the bores.
100% having a moment of turmoil at the moment though haha

In all seriousness doing a refresh on the V8 - along with a suitable box cough manual cough will pay dividends in terms of drivability and confidence. PLUS I would imagine with the EFI it will be quite economical. You can then do a full rebuild on the 6 cylinder and put it under the bench for the next 15 yers before scrapping it as you realise that once you have a v8 you can never go back.... I did see recently a chap that mated a BMW ZF box to a small block so would imagine it would be quite easy to do the same to the Ford. Scrap that - for the price of the adapter kit you can get a T5.... P. |

when you say duty cycle, do you mean the injector cant physically open and close quick enough, to deliver the least amount of fuel possible, to suit your engine ?

The duty cycle is at around 1.5% on idle and it is too rich at that, so it's basically at the minimum amount of 'on' time for the injectors and that's too much for my tiny motor haha
I tried unplugging one of the injectors to see if that would help, but it wasn't happy about that at all and just started freaking out big time.
I knew I was going to be pushing my luck with the Sniper I bought, so this doesn't really surprise me. I think they advertise it for minimum HP of 200 and mines kicking out around 120ish maybe a little higher now it has a bigger cam in it, but not a lot more than that.

Might worth turning the fuel pressure down a bit?

How about making a new adapter, so you only use 1 bore of the throttle body?
Split Weber - racing Mini style...

Might worth turning the fuel pressure down a bit? The regulator is built in to the unit and can't be messed with, so I guess I could look to block off the existing return and setup a standalone regulator.. hmmm that might be worth thinking about. |

I'd still end up with 1 bore trying to chuck fuel somewhere, it really didn't like having one injector disabled and I stuck a bung in one of the bores when trying that to see if I could get it to run but it was just freaking out big time. |
