M16 engines...

by Frank Drumheller


the original engine is a Studebaker built 226 cubic inch, flathead, side valve, six cylinder engine. The stock engine developed 90 horsepower in 1941-42 and increased to 94 horsepower after WWII. The engine was a modified car engine from the Commander car series, therefore, the engine was, and is, referred to as the "Commander" six cylinder.

The engine numbers for an M16 would be patterned 3M-xxxxx. If there is another numbering pattern, the engine is a replacement from the later 2R or E series trucks which are 245 cubic inches, or the engine may be an unnumbered reman engine or possibly an engine of another make.

If you would post your serial number, model code, taken from the tag on the driver's seat riser and your engine number, I'll be happy to decode the three so you'll know exactly what you have. Thanks for sharing with us. We're interested how your truck turns out.
