Did you use one bolt in the center that holds the manifolds together to also fasten the injector rail to the intake? That is clever engineering, if so!
Yes. As you can see I am running headers, so it seemed logical to utilise the available hole in some way to tie the rail down. The alternative I considered was to drill and tap the manifold to tie down the rail. I was worried that with the current attachment method I did not have the rail secured at it's endpoints. Fortunately the rail itself is very stiff, so securing it from it's centre has been good enough to keep the end of the rail from lifting off the injectors and mounts.

Are you worried about fuel puddling issues with the injectors pointing straight down. I have read many ideas on the subject, but the one that makes the most sense to me is to have the injector spraying towards the valve. In the slant six's case, the injector bung would be angled slightly(laid back away from the head). Also, how did you determine the depth to insert the injector tip?
No, not really at all. In your readings you will no doubt have seen injectors mounted in all different positions and angles. I have even seen injectors mounted pointing away from the combustion chamber! Anyway, ease if implementation was my principle motivation, and the majority of the fabrication and machining work was done in my friend's garage. Perhaps if I angled the injectors I could get reduced emissions or something, but not enough I would think to make a difference that I would ever notice on a stock motor.

The injectors are mounted with their tips flush with the roof of the runner. I tried hard to ensure that there was nothing protruding into the runner itself, however on cylinders 5&6 the injectors actually do stick out about 2-3 mm into the runner. Putting a straight edge across the intake manifold revealed that it was not straight, so the variance was eliminated by mounting the injectors at different heights. I had to do this because the fuel rail IS a straight edge, and the injectors had to mount properly in that if I was to achieve proper sealing.

Just much a stock mopar would look. :)

Very nice!

Cheers, Wizard
Thanks! That is exactly the look I was trying to achieve. I think the pod filter detracts from this, however I couldn't really come up with an easy to implement alternative. I do have a couple of different Brand-X factory air-boxes that I want to try and work with, but in doing so I will probably have to relocate the battery somewhere. Relocating the battery is not quite so easy if you want to keep the battery in the engine bay.

Thanks! I'm very proud of her.

I wish they continued the wagons up here after '66. Yours looks real nice. They have nice body lines.

is this mig or tig welded? where could someone find the fittings for everything? also how do the injectors fit to the rail?

Mostly mig, with the injector mounts brazed onto the manifold. The AN fittings can be found in any decent speed shop. The injectors just sit in the manifold and rail - there are O-rings to stop them leaking under pressure, and the rail is clamped down to the head and manifold, but you can simply pull the injectors out when everything is undone.

Can't believe I missed this thread before. Looks like I took a similar route (Ford V8 throttle body on an elbow), but you have a much cleaner engine and installation.

your setup is sooo sick!!! :shock: Im thinking of the efi route and that gives me a good idea. I thought I'd let you know I WANT YOUR HEADERS!! those are way cool, you aussie's are spoiled with all those cool parts for slants.

Hmmm. A clock and side window venecian blinds. Your options list looks a bit different than ours too.

Thanks for the compliments fellas.

I think it's funny how you blokes in America reckon we are spoiled for bits and pieces here in Australia. Surely it's the other way around! :lol:

The clock is a Mercedes Benz unit, although our '71 Valiant VIP (long wheelbase Valiant) had a factory clock that looked similar.

The venetians are still available new, made by the same factory that produced them back in the day. I got mine new for my birthday last year.

Intake temp is a real problem with my setup, and it will be rejigged soon so to get some cold air into the intake. I need to relocate the battery first...

I recently took her on a 700mile road trip to the biggest Chrysler show in Australia. She ran relatively problem free, and returned 20mpg for the trip (speed mostly sitting on 70-75mph). I'll be swapping in a new computer soon and will spend some more dyno time to hopefully get her a bit more fuel efficient.

Oh yeah - I had a rocker cover sticker made up by a bloke in America. Great job!

I would like to point out the inspection plugs in the cowel. These were very much needed, and not present on US A bodies. It would have been nice to get in there and pull out all the leaves and such that accumulate and rust in there. I put some in mine, but they didn;t look as neat as yours. Are they factory, or did you install them? Again, nice job.

What do you not like about your ECU?

They're factory fitted on all Australian Vals from '63 (AP5-I think, someone will correct me). Plenum rust is one of the the most common problems in our cars, and the plugs can help keep it under control. Here is a pic of my other project which shows the cutouts well.

Re my computer: I've got a baffling problem that doesn't make sense. The computer has been returned to it's manufacturer, only for it to be returned with "No Fault Found". I've made changes as per the manufacturers recommendations trying to eliminate other possible explanations for my problem, but to no avail. In the end MicroTech have agreed to give me another computer to try out. Here's hoping it solves the problem.

Cowl plugs: Deleted from North American A-bodies after '66.

Computer: Check your earthing, then improve it even if it tests out as OK!
