Thanks for the heads-up, and I'm already on it! I already measured the space between the top of the diff and the floor, and used that as my measurement as to how deep the notch reasonably should be. I want to cut as little as necessary because hooking up a trailer is still important to me.
Here's an image of a shop built notch. Not much clearance gained for the work but it is what it is. I bet if you extended the plating on both sides of the frame to where it's just below the floor (box the inside of the rail & plate the outside portion), you gain strength & could go ~3" into the rail. wouldn't have to cap the top off making it an easier install (as long as it doesn't trap moisture).

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
