    351W EFI into Classic Rangie

    G'day folks,

    I thought it was time I moved this into the correct forum.
    So following on from this thread...
    http://www.aulro.com/afvb/wa-aulroians-group/110482-zf-auto.html

    This is my 351 conversion thread.

    After a trial fit of the engine and trans on Sunday it's looking pretty good.
    Here's a pic of the trans with the ZF extension housing in between under the car.



    And the clearance to the front driveshaft.



    The whole deal out of car again.



    Looks like we'll be able to get the transfer a lot closer because these bosses can be ground off the case for even more clearance.



    here you can see the original spud shaft is in place with the output spline up against it. So you can see there's even a possibility to have it closer still, once the new spud shaft is made. Since this photo we've decided that a 45mm spacer is what we'll use. So the ZF extension and the 4R70 extension have been taken off to be measured on a Zeiss machine and the data spat out to CAD for design.
    Hope to get the spud shaft design off to the spline cutters this week too.



    Nice strong 31spline output shaft



    Finally got the pan off tonight. Looks nice and clean.

    Ok, I took a sample 31 spline yoke and the stock spud shaft down to the machine shop today. Then they asked if I could bring the gearbox output shaft down but they also said that heat treating would possibly put it out of shape!? After some more discussion the price suddenly went from $150 per spline to $750 for two splines!?
    So who knows someone who can actually do this job in Perth?

    Stripped out the stock ECU and Harness today and, as I've decided to use an EB-ED 5.0L Falcon EECIV, I picked up a harness for $50 today also.
    Here's the stock harness...



    And here compared to the Falcon harness. You see there's a lot of extra wiring because ABS is incorporated into the Falcon harness as well...



    Here I've stripped out the ABS(the pile of wire and connectors next to it)

    Thanks Jeff,

    You're on! Hopefully sooner rather than later.
    Looks like we might be welding a yoke to the spud shaft at this stage.
    Because, apart from one place I went to who would machine an internal spline(but suggested it would be difficult), every other place either didn't ring back or didn't answer their phone in the first place!?!

    Pete.

    Thanks Jeff,

    We're going to try welding now but I would still like those details for future reference.
    "Farmport" told me about his AOD behind a diesel Landy conversion punching out over 600nm that he did 12 years ago and it's still going strong with a yoke welded to the spud shaft.
    I've got a 31 spline yoke from a BF GT which has a bit more meat near it's end than a std universal type yoke. This will be machined down and bored at the aforementioned end and then interference press fit over the slightly machined down stock spud shaft and then welded.

    Not a great deal Banarcus,

    Waiting for my mate to machine the adapter and the yoke and spud shaft so we can weld it together.
    The Optishift unit arrived the other day so I've been mucking around with the software. You can enable paddle shift with it too. I'm thinking of using a BA Falcon sequential shifter rather than bothering with a paddle set up.
    I got them to send me a digital range sensor switch with it too...they're better than the analog ones and besides the one on my box is smashed.
    The TCU box is quite small and has a bright orange LED display which shows what gear you're in and a programming/control knob so I think I'll mount it in the console near the shifter. Oh and I'll be making a new console because as you probably know the stock ones are ****e!
    I'm discovering what mods to do to the trans while it's out of the car so I'll be ordering some parts for that soon.
    Done a little more on the harness and will probably run the trans harness out the same big grommet in the firewall as the engine harness.
    Been looking at engine mounts and the EF-EL Falcon ones look good if I can get them in there.
