I am working on a 1955 M38A1,with an L4 134 engine and i ordered a crankshaft and bearings they sent were the wrong size I was wondering if anyone knew what the original size of the main and rod journals would be so I can order the correct bearings
Thanks;Dennis

The M38A1 originally came with a F head engine (intake valves in the head, exhaust in the block). That wouldn't make a difference in the crank though.

Standard Mains: 2.3340"
Standard Rods: 1.9375"

MEASURE THE BEARING JOURNALS AND ORDER ACCORDINGLY any other method is foolish at best.
