Hello again.
I could not find any information on the Chrysler six at all.The other motor is a Dodge 230 cubic inch engine.My book says used from 1942 to 1962 for industrial uses,and 1942 to 1959 passenger car and trucks.Trucks and industrial motors used forged steel cranks and passenger car motors used cast cranks.Some motors also used steel camshafts.We have a wagnermobile forklift at work that uses a spitfire motor in it.It has a geardrive camshaft and not a chain and sprockets like the others.I have replaced the motor twice in 22 years.Thats a good service life. Always save the head gaskets as they can help ID motors.Also the head gasket can be used to make new solid copper gaskets.In Canada they had a 230 motor based on the Chrysler--Desoto size block.Also early Sherman tanks used 5 Chrysler spitfire motors in them.It was called a multi bank engine.Desoto size 251 motors were used till 1968 in Miltary W300 trucks. My friend drove his 1940 Dodge 3/4 ton pickup to Mexico in 1967 to tow his 1951 Chevy home after it broke a crankshaft.It used 14 quarts of oil to make the round trip.No excessive smoking tickets back then.Sorry I could not give you more info.Goodluck,
