Yup, no doubt about it, the 366 is the red headed step child of big blocks. As a former farm boy I have had C65's going right side ways through mud holes in 3rd gear with the glasspacks blattin'. I didn't have tachs in them but I'll bet they will rev to 5k rpm. Diesels just sink in the mud because they don't have any wheel speed and no rpm range.

I still wouldn't pay too much for one. A lot of farm vehicles are very low mileage though. If you buy a low mileage one it would last a very long time.
