What's the best way to reinforce the frame behind the lower motor mounts, removed my 330 to install my 363 and noticed that the frame was cracked right behind the lower motor mount. I notched it and welded it up but I think I need to reinforce the frame in that area now! What do you think?

I've broken a bottom motor mount twice and cracked the frame right there. Cut the old one off and made an oem looking one to replace it with. I then took a flat piece of steel and cut it to the length of that square tube the motor mount is on and ground on it till it fit perfect. I had it welded into place on the vertical back side of the motor mount tube. I haven't had any more problems. The tubes that hold the motor mount are very thin and welding on them just seems to make them more brittle. It will usually just end up cracking right next to the weld the next time. This is how I solved that problem, but I'm sure there are other ways. I didn't want to cut out and replace the whole tube, so I made basically a reinforcing plate for the tube and welded it all the way around that plate on just the one side of the tube. I did it to both mounts tho and haven't had any more problems. Good luck. Sorry for the long answer, but I wanted to try to explain as best as possible. It sounds like you have some fab skills and tools, so it should be an easy fix
