Hi Bob,
I could have gone 4.11 but it meant I would have had to change the carrier. The 3.90 gears are a straight swap.
The Keisler box is 2.66, 1.78, 1.30, 1.0 and 0.68. This should keep things nice and tight.
The only problem I can see is the engine not liking the low revs at 110 K's in fifth.
My new shed pad is getting poured tomorrow and the shed erected in two weeks. Finally I'll be back in business
