1949 studebaker truck engine interchange question

1949 Studebaker 6 cyl pickup engine is locked up. I wanted to know what other years and engines would interchange with that. thanks for any help

Just a thought, you might want to put a 50/50 solution of acetone & auto transmission fluid in the cylinders and let it sit for a while to see if it will break free.

They made 2 engines, a small 170 cu in Champion engine and the larger 226 cu in Commander engine. The larger engine was increased to 254 then replaced by the V8 in 1951. It continued to be used in trucks for a few years.

The Champion was increased to 186 and continued to be used in cars and trucks, and was redesigned into an OHV engine and was used up to 1962.

Unless the rod is sticking thru the block it would most likely be best to rebuild the engine you have. Any engine you find will be 60 - 70 years old and most likely due for a rebuild itself.

It would help to know what kind of truck, and what kind of engine you have.

If you have the model # and the engine #, I can give you the interchange info from a 1950s Hollander Interchange manual

the 170 is in a pickup

According to the interchange manual, the Champion engine was used in the following vehicles:

1947-49 Champion

1941-48 M5 truck after Engine IM-8566

1941-48 M15A truck after Engine 2M-7795

1949-50 2R5 & 10 truck to Engine 1R-95492

1949-50 2R15 truck to Engine 2R-12076

"Champions have starter on left side while trucks have starter on right side. To interchange pass and truck switch starter to proper side by installing rear mounting plate, oil pans, filler tube and oil stick from replaced motor"

There is also a note that some earlier engins can be used but changes in addition to above are needed-timing chain cover, drill hole for oil stick, etc. Also some earlier motors have shorter stroke and less horsepower and therefor are not recommended.

Hope this helps. Good luck!

You should be able to use any Studebaker Champion 6 right up through 1960, if you swap the oil pan, etc. as mentioned above. There were some 185 cubic inch engines in the late 1950s, but these fit also. The later engines also used an electrical temperature sensor, so the head might need to be drilled and tapped for the sensor well. There should be plenty of these engines around at reasonable prices.

thanks for the help
