Transmission question from post #16. What's different between passenger and commercial??
I had a commercial some years ago and had to figure out what it was. I guess an easy explanation is it is built heavier duty and accepts normal 85h.p. gears. Tower is a passenger type 6 bolt versus the 60h.p. tower that is attached with 4 bolts. The gears in the one I had were geared very low for a commercial application but you could theoretically swap a '39 type gears and tower to this case. Behind a built 60h.p. engine maybe it would go like a dream. Sold what I had years ago but is an interesting variation as well the fan with the longer snout. Its a beauty as presented. Thanks Lawson for your work!
