Re: 36 C1
They show a HD-2 HD-3 and HD-4 Then it jumps to the FAx series in the heavier trucks.
There was a HD engine that was smaller than the 213 , one hundred something. So looking at the book and making the best educated guess (I will be glad to be corrected if someone has some solid info) the HD 2 which came in the lightest trucks was the one hundred something and the HD3 would be the 213 and the HD4 would be the 232.
Unfortunatly my Motors manual doesn't list the internal specs for any, no bore, stroke or displacement given. Not even for the FAx series.
My K manual only lists the GRD engines, but does mention the smallest one at 175 CID, so I would guess HD-2 175, HD-3 213, and HD-4 232 or somewhere close to that.
