PLEASE help! 360 vs 273 oil pans different?

I plan to use a 1/4" thick washer/spacer to get the engine off the k-member some to get some clearance.

I had to make spacers too, but to allow clearance from the Dougs Headers to the Steering shaft, and torsion bars. I didn't go as big as 1/4 though. The headers had to be DEAD-ON to clear everything. :banghead:
