I'm using this pan on a megablock , plenty ground clearance , i use a sandwhich plate between block & oil pump , the oil line is routed between sump & K frame , i've had zero isues with oil pressure , also have no problems with oil draining back to sump as the feed line comes into top of pump , no need to pull dizzy when motor has been sitting a while.

I also use regular mounts , if i was to come into bottom of pump then i would have had to notch the K frame , i know some don't like this idea , but as said , no issues with oil starvation.

EDIT , i've seen oil pump adapters that exit to the front of motor , had i known @ the time i would probably gone this route.
