I'm in the process of building the cross-member to support a turbo-350/205, and of course a s.b.350. What I need to know is, how important is having the tranny pan sitting level and the block tipped down in the back-like from the factory? I'm trying to keep the block low between the frame and the t-case up high for ground clearance. Once I get this figured out I can go on with 4-linkin the rear.

I'm interested to see the answer to this. I just mounted my motor with only a couple of degrees slanted back and my trans pan (TH350) isn't level either. I assumed it would be ok since it's very close to level just not exactly.

how often are you driving down the road/trail on a perfectly level road ?

I think you'll be fine.

I taked to a friend today thats been building engines for ever, and he says that as long as you put a bigger pan on, it will be fine.(tranny) All of our trails are uphill, so I'm thinking this will be in my favor.

If all your trails are uphill ,how do you get home?
