Truck engine?

Did 49 to 53 truck engines have a 4" stroke? I have one in the barn that was pulled out of a dump truck about 20 years ago.

Looks like the short block was replaced on a truck, and they kept the bolt-on pieces. Looks like an 11" clutch? Truck pan? Pretty common to see a mish-mash of parts. Trucks were 3.75" stroke.

8CM indicates 1949 Mercury heads. Water pumps are 1951 mercury narrow belt.
8RT indicates pickup truck intake manifold to replace the 4 bolt Mercury carburetor. Oil pan looks like '49-'51 Mercury rear sump. 4 inch crank is a Merc crank. I don't think Ford trucks came with a 4 in. crank. Not sure if Mercury pickup trucks had a 4 in. crank. If bell housing is made of stamped steel it's most likely a 1949-51 Mercury. If it's made of aluminum it's a truck bellhousing for the 11 inch truck clutch. If the clutch disc dia. is 11 in. it's a truck clutch. Your clutch looks like a 1949 Mercury clutch. When your tear down the engine part number will appear on the cam. I am surmising that what you have is a 1949 mercury block with other parts bolted on.

Is this true? I always thought they were cast iron. I have turned down offers of truck bellhousings because of this.

THANK YOU. I stand ( or sit) corrected. I think you are correct about it being cast iron. Here's several 11 inch cast iron bellhousings for sale.

Convincingly looks like the stamped Merc bell. DD

'49 Mercury heads did not have the oil filter bosses cast into the head, they used the head bolts also narrow pulley water pumps were used in 1950.

Thanks to all. Wanted someone to verify what i thought. Bore is near stock if not stock, measured with dial caliper.
Thanks again.

Every thing except the intake says it's a '50 early '51 Mercury engine.
