[AT] MF 1135

[Mark Greer]

The 8070 has a 426 that is "turned up" from the factory (145hp drawbar, 
170hp PTO) when compared to a lot of other 426 A-C applications. When he 
found he needed a new block he ran into a lot of junk blocks that were 
broken in the same place as his and also found numerous tractors that had 
ended up in the salvage yards because a new engine or a re-power was more $ 
than the tractor was worth. When he did finally find a decent block to start 
over with it was expensive. The Cummins route gave him a good bit more power 
(200hp PTO) for similar $. The Cummins is not being worked as hard to make 
that extra power so it should last longer, not to mention parts availability 
is better since the Cummins is used in considerably more applications than 
the 426 A-C was.
