Flathead Blocks
November 27th, 2007 | Published in General
I have been collecting up flathead blocks for a couple years now, finally got around to stripping them down and bringing them to the machine shop. The got solvent washed and scrubbed to the point where all the 50 year old oil and grease was all gone. What a difference. We magna-fluxed them to find out which ones had cracks.
I brought in 4 blocks, 3 8ba (a 52 truck, a 50 truck, and a 50 car) and one 59-A (47 truck). After doing 3 of the 4 so far i have one bad 8ba block (52 truck) with cracks in both the cylinder wall and the valve area, and one good 8ba block (50 car) which has a water jacket crack, between a head bolt hole and a water passage, this is the most common and totally usable. The 59-A (47 truck) motor is also good with no cracks at all! The third 8ba will be done soon but i am extatic about the two good ones.
The 59-A block will go in my model A project and the 8ba will go in my 50 ford shoebox project… which means i can use the flat 6 which was in the shoebox, in a roadster pickup. YAY!
