Flathead project
This is a flathead motor I bought to tinker around with, I want to learn more about these motors. I believe it's a 39 to 41.
101_0884.jpg 101_0882.jpg Will attach more pics as I brake the motor down.. |

Re: Flathead project
Side view shows the '39-40 bulges, it seems to have the long crank so not 1938.
Next--pop a head and we can tell for sure whether 221 or 239 originally. It has pulley setup for big truck, and many of those came with 239. |

Re: Flathead project
It was out of a big truck or a stationary engine. It had a generator fan. Sounds like a worth while project. G.M.

Re: Flathead project

Re: Flathead project
Weren't the bell housings attached to the block up until 1948 or 49? After that they could be split off, I think..???

Re: Flathead project
From here I'd call it a 42. It will pass the pencil test and I cain't see any bluges in the pan rail for any core plugs. See if the intake manafold gasket surface is raised up a little from the block. Walt

Re: Flathead project
Hey GM. I remember that, it was a nice summer day. You and your wife and a friend of mine, we set in lawn chairs in from my shop and had great visit. I remember you drove in my drive and got out, opened the hood and pointed you heat gun at everything under the hood,it was running as cool a clam with Ships pumps, 6 bladded fan, shrould. Stop in again when you go to Nova Scotia. Walt

Re: Flathead project
I don't see any sign of the steel sleeves in the bottom end pic. If it's still 3-1/16 I'd call it a 39 engine. Walt

Re: Flathead project
In your first photo I noticed a chain hoist. I fabricated a couple of straps and bolted them to #1 and 5 exhaust ports and used a hoist to stabilize the front of my 8BA until I can make a side exhaust plate for my stand. Cheap peace of mind.

Re: Flathead project
I took the oil pan off, there is four freeze plugs. Does that make it a 39 to 41? The person I bought it from said it came out of a truck. The water pumps also had double pulleys......
