1950 9G Studebaker Champion Engine - Mystery Solved

The ongoing task of identifying my Studebaker Champion's engine has been solved by Dwain at alt.autos.studebaker.

"Yes sir, a 1950 engine, the original engine probably. Now that we know that, I'm not so sure whoever installed the later ('55 - '57) head did the right thing. That 536180 head was designed to deliver 7.5 to 1 compression ratio on a 185 engine. When installed on a 170 engine it probably delivers at least a half point less, maybe as low as 6.5 to 1.

That's not a great big deal, so if you are okay with the way the car runs now, I wouldn't change anything. If you do want a little bit more power and mileage you could try to find the 1950-54 head #529279 or the 1960 head #1549218."
