Diesel C60?

[ClassicTVMan1981X]

While I know about the use of the 4-53 Detroit Diesel two-cycle engine as well as the Toro-Flow D-478 V-6 in these, I wonder if any of the '67 to '72s were changed to the "Fuel Pincher" 8.2L diesel V-8 (available naturally aspirated up to 165 hp, or turbocharged with 205 or 230 hp) during the 1980s?

In theory, because the 1980-84 Chevy and GMC B6P school bus chassis did use the 8.2L, I believe these '67 to '72s could have had the 8.2L as a replacement engine for some customers. If any of you happen to have a '67 to '72 C50, C60 or M60 with the 8.2L, please let me know. Some of the '78-'80 C50s, C60s, M60s, C70s and M70s could be had with the 4-53T two-cycle diesel.

For all you D-478 fans, this is what that engine sounds like (in this 1971 GMC TDH-3301 bus):
