Engine Swap - Motor mount help

[Cam-Shaft]

Hello all,

I'm 18 and attempting my first motor swap. The old motor (SBC 307) is out and the new(er) one (6.2 diesel) is in place and bolted to the tranny.

I could not get the engine to fit over the cross member while putting it in, so I unbolted it and slid it forward 3 inches or so. Now that the engine is bolted in place, It will not slide back all the way but instead hits the oil pan. What are my options here? It fits fine over the shallow part of the pan but hits the deep part, so it seems the only option is to notch the cross member and reinforce it on the front side.

That being said, I Did bolt the motor mounts off the SBC on the 6.2 and the engine does sit a little low. I have no problem creating spacers for it, but I am wondering how you are supposed to tell what the proper sitting height of the engine is. It is a 4x4, so the Tranny and T case stayed in the truck. Do I start jacking it up until I see some weight on the T case mounts and thus know the proper engine height?

Hope you can decipher all that and give me some pointers.
