The thickness of the Morana t-chain gear and hub is less than .020 thicker than the OEM gear and spacer. The difference between the bushing flange thickness the mustang 30k mile T-chain cover and the SC cover is .013, that's more wear on the SC bushing. Again no smoking gun, but looking at the gears on my 30k mustang engine it seems like a shit design.


I have a lead on a complete 3.8 and if that works out I have a T-chain cover I can cut up to see the gear mesh. I have no problem machining parts to get this mesh any better.
I have heard of t-chain tensioner failures and I'm wandering what people think is best, the original design or much simpler new design. I really like the new design.


I want to get the bottom end together before I do much more with this gear issue. These engines have such tight tolerances and it sucks you can't get any .001 bearings for more oil clearances. I'm swapping shells around and struggling to get over .0006 and shooting for .002
