I took another look at the E4OD gearset- the tranny guy was right- it's a straight swap for the c-6. What that means is that is is a complete swap over- the whole works- ring gear, pinions and carrier, and sun gear replace the C-6 ring, pinions and carrier, and sun gear. They should fit right in the same space. Unfortunately, the steel carrier and six pinions are not interchangable with the C-6 carrier and pinion set.
The three pinion and aluminum carrier should be more than stout enough for a 200 hp engine.
The E4OD seems like it might be a canidate for a time to climb gearbox or for air racing. The nice thing is that you should be able to change from a 2.17/1 to a 2.75/1 ration with a simple swap of the gearset.
