i'd move the motor back (have the 205 centered right over the middle of your lower link mounts) and have the frame limit uptravel, not the oilpan. maybe even far enough to where the chunk on the rockwell could come up past the crank pulley. It'd give you room to bring the ride height down a little, and also help what looks like is going to be a ridiculous front driveshaft angle even at ride height, let alone drooped out.
When you do that you could also try to bring the driveline back to a somewhat level-er-ish angle. You won't need such an extreme angle if you lower the ride height. I'd clock the 205 too.
I'm kicking myself now for making a lot of mistakes the first time i built my buggy chassis. yours looks very well built, just take the time to get it to exactly where you want it before you're too far along. its a lot better at this point in the process than having you walk up to your shit with a torch and sawzall in 6 months and go to town (aka...me). the advice here is (usually) spot on. just my experience man. good luck

edit: you damn rockwell guys, nevermind the front driveshaft angle comment...
