Sorry... I missed this topic before, so I want to ask you: didn't Volvo bring the F10 and F12 (which outside of North America were known as the F88 and F89 respectively until 1977) into the U.S. market in 1982-83? They of course were the larger relatives to the F6 and F7.

Does anyone know the history of Mack transit buses up to 1960?

You know, all about their engines and transmissions. I know there were engines like the END672 and transmissions like the Spicer 2-speed synchromesh V-drive transmission.

Thank you,

Did the 237 or maxidyne design have and influence from Scania or was it 100% designed by Mack?

I am not sure... I would think both were Mack originals.

How many of you know about the joint Mack-Scania diesel engines, including the six-banger ENDT475 (E4 in 1979) and the ENDT865/866 Thermodyne (to be replaced by the EM9 Maxidyne in 1979)?

Is it true that there were two versions of the Scania DS14 series V8 diesel, one with the 5-1/4" (133mm) bore and 5" (127mm) stroke that the Mack ENDT865/866 also uses and another with the 5" (127mm) bore and 5-1/2" (140mm) stroke that had been on the Scania roster through the late 1990s (before its supersession by the DC16)?

Thank you,

Ben
