1939-53 Ford Mercury Flathead V8 NOS Crankshaft 3.75 French NEW 304

Overall length is 26.030". Wide counterweight is approximately 6.0". Clean-out holes are the large 0.6250" (5/8") type. Main journals measure 2.4990" (see picture). Rod journals have 2 oil holes and measure 2.1390" (see picture). These measurements are consistent with a stock uncut crankshaft. Stroke is 3.750".

I bought several of these crankshafts from a hot rod shop that closed. They are all brand NEW never installed NOS French military surplus crankshafts. This crankshaft has been inspected and polished to confirm it is good to go. I have other crankshafts that still have the original "cosmoline" brown, wax-like petroleum-based corrosion inhibitors. There is minor surface/flash rust and shelf dirt. The unpolished crankshafts are for sale in a separate listing (not this listing).

According to VanPelt, these length and main journal dimensions should fit 1939-1953 Flatheads. This crankshaft has 2 oil holes on the rod journals so you can use with early type full-floating rod bearings or you can also use 8BA, 8CM, and 0BA connecting rods and the insert type rod bearings. Rod journal dimension is consistent with 1946-1953 Flatheads.

Possible original numbers:
29A-6303B
8BA-6303
1BA-6303A
99A-6303B
29A-6303B

Please verify this will fit your application/build.

See pictures for details. I also have several NOS unpolished crankshafts availble.
