    I have an older hot rod friend (84), that is building a 1940 Ford truck hot rod. He has the early 60's 394 Olds engine mounted in the frame, and bought a Muncie 4 speed trani to put behind it. He is a machinist, and built an adapter to mate them up, but has no room for the fork. He came to me for advice, but I'm a Flathead guy, and have limited knowledge of mixing up engines, transmissions, and adapters on the later model stuff. Anyone out there know what it takes to adapt a Muncie 4spd to 394 Olds?
    Thanks,
    Zane.
     
  2. Not sure about help with the Olds/Muncie hook up but such a project should be shared. How much more HAMB friendly can you get?
    And at 84 years! Bravo!
    How about a load of pics of this baby? Inside, outside and all about.

    Reo has never taken a picture of anything the whole time I have known him. But I can check with his son and see if he has been taking any of the build. If not, I have a few pictures of a couple of his hot rods and him, and in the back of one of the pictures is his 40 build. I will check and see what his son has, and post later.

    I have done a little more research on the subject here on the HAMB, and have come up with some threads from years ago covering the 394 Olds to Muncie topic. So if Reo would like, I might turn this thread into his 40 Ford truck build.

    I'm only 81 so he might not value a young punks advice but he could check out a Mcleod hydraulic throw out bearing as it uses flexible lines that can be routed through the bell housing in various places. 1960-62 Chevy trucks used a throw out arm on the passenger side of the bell housing so with him being a machinist this might give him some ideas. My first rod was a 34 Ford 5w with a 303 Olds engine that I couldn't afford the starter change over so drove it two years with no starter. It was my only way to school and work but I lived where one was never far from a hill or good slope so no problem.
     
  7. I've done several SBC manual trans in early Fords including a '40 coupe with stock pedals. I moved the clutch fork and pivot to the pass. side and used a hyd. slave cylinder. If he adapted a SBC bell housing to the Olds engine it should be an easy job for him.

    64-67 Chevy II V8 belhousing has the throwout fork opening at 7:00 position.

  9. I have one of those, but it didn't appear to fit with the '40 brake pedal either.

    No, not the same. 49-64 big Olds had a stand alone bolt pattern.

    Ok, Reo agreed to the build thread, but said it would be slow. There haven't been any pictures taken of the project yet, so I will be starting off with pictures of where he is at today on the 40 Ford truck. But first I will post a few pictures from his past. There are not many because he said he could buy car parts for what a camera, film and developing cost back then. He does not have pictures of his last 40 Ford truck, so I will start with his 32 Ford coupe.

    More of the 32 Ford. Reo doesn't spend much money when building a rod, he pretty much builds and fabricates & machines everything he needs.

    Here are a few pictures of his last two hot rod builds that he drives the wheels off of, a 34 IH truck, and 20's vintage roadster. In the back of the first picture is his 40 Ford truck with the 394 Olds Rocket engine that he is currently building.

    Here are pictures of Reo's 40 Ford truck project already in the making that I took today. I will go over occasionally and take pictures as he builds and post them. Random shots, no order.

    Thanks, I think Tony is who he bought the flywheel from.

  24. When I had the Olds. in the 37 Ford I used a throwout fork from a 1950 GMC 3/4 ton truck it was cast steel . Still using it with my Caddy To Muncie set up.

    Is that old Olds bellhousing from a manual, or an automatic?

    Is the 215 Olds motor in the roadster a stock one, or does it have some goodies in it? I see it still has the stock air cleaner cover that totally covers the carb and seals to the intake.

    Looks like a hydramatic bell,
    Would a hydraulic throwout bearing work?

    If it were me I would stack adapters

    An early olds steel ring to early ford trans then get a GM trans to early ford flathead adaptor that uses the ford throw out bearing /arm and use stock pedals

    That was a clever way to adapt the 4 spd to a 394. If there's an issue with the trans being too far away from the crank or too close, I would opt for Thirtytwo's suggestion above (I'm doing what he said with mine) But if everything bolts up fine and fits the clutch and pilot bearing then check with the hydraulic throwout bearing suppliers for a recommendation based on how much room you have left in there for a throwout bearing. They are way easier than mechanical linkage.
