First swap help.

I have the short wide mounts with energy mounts it is as low as I can go without the inner tie rods hitting pan so I'm cutting the tunnel and raising it up 2" so in the futer if I want to change to a 5 speed I have room. No problem with mid length headers

just an idea: you could lower engine down and notch the oil pan for tie rod clearance. A little easier than messing with the floor

I don't need to go up much on the trans yoke I'm at 4.3* now and I'm running the Holley 302-2 pan so if I can get the yoke up to 3* I'll be happy with that.
