Small update. Proposed and all of the stuff triggered by her acceptance has eaten a bunch of time, but I've gotten some time in on the project. If I didn't at the beginning I should have warned y'all that I normally move on projects about like molasses and this project is proving to be no different.
All of the SYE parts except for the partial rebuild kit arrived late last week. I've got the t/c apart and mostly cleaned up. With a final cleaning it will be ready for all of the new parts and assembly. The trans guy is taking his sweet time, but I don't need it yet so I'm not pushing for it too hard.
In the mean time I've got the front 1/2 of the t/c's case bolted to the mock-up trans case. I'm going to want a clocking ring to put the front drive shaft further over to the right and to keep the t/c's case from hanging too far below the bottom of the frame, so I just ordered that from Kert @ DIY4X.com. Good guy, recommended vendor.
As I suspected a while back, the trans-t/c to floor interference is the limiting factor in how high I can mount the power train. The t/c has a bolt boss that will hit the underside of the floor once the clocking ring is in place. So I'm stalled on engine placement until the clocking ring gets here. I don't really want to go there, but a 1" BL would sure open things up quite a bit.
In looking at where the stock engine mounts are and where the exhaust is likely to need to go I'm starting to think that going with a mount like these:
Chevy Weld-In Motor Mounts might be a better idea. I had wanted to use the stock mounts for ease of replacement parts, but they use up a LOT of room where exhaust might need to go.
The engine is currently sitting in the truck at 7* relative to gravity while the rear pinion angle is 2.5* relative to gravity. Since I have to make major mods to the axle housing to center the pinion anyway I can re-set the pinion angle, but I don't think that I want to go as far as 7* so a DC rear drive shaft may be required.
EDIT: Turns out that the Speedway parts are on back order. I have some OME urethane bushings that I could make something similar from, but if I do something like that I want the bushing application to be for the FJ60 as that will make finding replacement parts much simpler. I called Kurt @ Cruiser Outfitters and he was kind enough to look up what I had. Dimensionally I though that they were marginal. The FJ parts would've worked better. In the process I find out that Kurt stocks the OE rubber spring eye bushings! I much prefer rubber in engine mounts to urethane, so I've got 8 of those on the way.
