We used to have an aircraft tug with a poly head 318 in it. Another company I had worked for had a diesel re-power job replacing a 354 CID gen I Hemi.

Old folks home I did a nurse call at had a nat gas 225 generator in the basement.

Electrical school I attended as a student had a 318 generator which we were replacing at the time with a big Caterpillar.
