[QUOTE="G Racing, post: 40110, member: 31"] A well built Allison will handle 800 to 1000 hp. A stock Allison does not like 500 hp. You can buy all the upgraded hard parts just like you can for the 4r100. money wise you will be way ahead to get a built 4 r100 especially from John wood. They make all the parts to put the Allison behind the 7.3 but it will cost you your check book to do the conversion and the build. If money is not an option put the 6 speed ally in it:rockon: it will be different. If you are on a budget stick with a John woods 4r100. Just my .02 worth [/QUOTE]
