Thank you guys!
Here is a little update on the work I'm doing to stiffen up the front end, it's really coming together now!
What I've done is bring tubes from the roll cage into the engine bay in a triangulated 3d structure that should prevent flex in any direction.
You can see the tubes are coming from the top and bottom of the A-pillar and then coming back to an additional mounting point in the center of the transmission tunnel.

There will be another brace across the front of the engine but first I am going to take the engine back out and weld everything I've done so far. I also need to make a bracket and mount the dry sump oil pump to the engine to make sure there will be no clearance issues with the brace at the front.
