THE BOARD / Re: MC 5a conversion to 6v92 Allison 740 questions.
« Last post by iree75 on March 31, 2025, 09:29:58 AM »When I picked up the 6v92 it has a 740 with it. (Looks like it had a module for an air shifter attached). My thought was to cool the trans with a seperate cooler / fan to keep the cooling load off the engine system. Would it be easier to run the 8v71 with the 644 in the 5A? Would would be involved in the conversion from a engine/trans mount standpoint. Sounds like that might be the way to go rather than adding larger radiators on a 5A ? Side note: Bought and drove the 5C 1100 miles from north of cincinnati to austin tx this weekend with minor issues... had to stay at 55mph in the Texas heat to keep temps from creeping up.... though its a super clean bus... I got it for parts for this conversion. On the 6v92 that I bought, the exhaust manifolds feed the turbo from the back of the motor... while its more of a side mount (not the typical truck application mount), it's still on the top of the engine over the left valve cover (when looking at it from as mounted from the back of the bus). Thanks for all the responses.. willing to sell the air horn?
