The 7.8l was a very good engine.The 7.5l is even better - more horsepower, better fuel economy, just as reliable as the 7.8l. Both real good engines, the newer of the 2, the 7.5 is the better one though. During the TR97 is when they changed over to the 7.5l. Easier to change engine oil on the 7.5 - only 1 filter and it is mounted at the rear side by the muffler bracket, not inside the hopper anymore.
