Engine mounting

[sgo70]

I was mocking up my engine today to see how it fits and it brought up some questions. I have a 6" ride height with a 5.5" z in the front so this is what I'm thinking: I want the tranny pan 2" above the bottom of the frame, with the cross member in it should be level. The engine mounts will be about 1" below the z'ed front rail putting the oil pan a little above the lower frame rails (about 6.5"). It fits but not much room to spare and I was thinking of a tubular crossmember mount that would end up with about 5" clearance.

Oh yea it's a SBC with a t400. Also when I put the 3 degree's down on the tailshaft the carb isn't level. Is this a problem or am I mixed up, the rear axle is 3 degrees up. I'll post some pictures but does anyone think this is too low, my body is going to be channeled so I'm trying to get extra foot space!!!

Heres some pictures:
