Re: Holy Crap! Kindergarten kids stamped my block. What do I have here?

The only change to the crankshaft was a larger bore hole at the back so that the big torque converter stub would fit in there. They did this for both 239 and 255 cranks in 1951. This was the first...

Re: 1932 ford pickup GVWR.

What ever it could carry with the rear tired still holding it up and the front tires still on the ground. Folks weren't real interested in stuff like that unless they were heavy haulers and those...

Re: Identifying a Cdn Mercury Flathead Heads

As mentioned 8CM or C8CM (or later replacement C1CM) heads would have the larger clearance volume for the 255 CID to have the same compression ratio as the slightly smaller 239 CID engines. Canada...

Re: Holy Crap! Kindergarten kids stamped my block. What do I have here?

When the automatic transmissions and the new rotator valves came out, the 1BA designation was used for the engine block. All the blocks were the same whether 239 or 255 CID. The crank was changed in...

Re: Overdrive Transmission in a 1952 F1

I just wish that some entrepreneur would start manufacturing new hard parts for the Tremec T170 RTS 4-speed TODs. The good ratios are getting harder to find.

Re: Rivets or weld?

Riveting is preferred to bolting of structural elements in aviation. Bolts don't expand in the bolt hole like a rivet and the weight savings can get astronomical on large structures. The way a rivet...

Re: Reamers

Many of the early King pin reamers were of a set size with slots cut in them to allow the flutes to only be expanded a small amount. They had a threaded adjuster inside with a tapered cone to force...

Re: German H-block?

The G29T from the first link looks like it has a 1953 date code. They manufactured them a lot longer than Ford USA did. Finding the wartime stuff is difficult but it's likely out there.

Re: Overdrive Transmission in a 1952 F1

PC-7 epoxy is the most commonly used material since it is more putty like and easy to work. Some folks use lacquer thinner to smooth it out.

Re: Tattersfield, a piece of history.

Tommy Thickston designed stuff like that but some design was likely done after his death in 1946. Tattersfield & Baron got the tooling after Tommy died. The intake manifolds may have been more...

Re: BorgWarner Overdrive Questions

These were fabricated by several people a number of decades ago. They used the Borg Warner components to put an overdrive into the torque tube. The transmission still shifts as always but the...

Re: 8ba v8 ignition coil questions

Check the easy things first is a good way to troubleshoot. A non-functioning load-o-matic system will definitely cause higher than normal coolant temps. Operating with no advance is problematic as...

Re: What are the advantages of upgrading to Hydraulic Braks

Re: German H-block?

The engines manufactured in the Koln plant generally have their casting marks. I think the 29T was early and G29T was later. They have different heads and a distributor mounted on the back above the...

My old parts book lists the 91A-14600-A as fitting all the 1939, 40, & 41 cars and trucks with an exception for mid 1941 on. The Mercury P/N 99A-14600 is the different one in those years till mid...

Re: Holley 4150 carburetor development history

Performance was good enough with the 4100. The only problem I had with them was with the secondary vacuum actuator diaphragm. The diaphragm parts available to me at the time didn't hold up well over...

Re: C69a

It's just like a part number on the engine series. The 6 represents the design year and in this case it's 1946 so it's post war Canadian with the C at the front. The 9 stands for 239 CID. The C69A...
