Determining engine/ trans angle

I'm putting a 4.8 l Chevy vortec and 4 l60e in my yj. I'm thinking I want to do a custom fab cross member for the transmission mount. Even if I don't and re use the factory skid plate with some mods, what sort of angle should I be going for? Keep it sort of the same as stock or drop it down a little to account for the lift. I've got an sye on the 231btw. Opinions?

In mounting a different motor, watch for hood clearance. I wanted my motor up a bit to help with the oil pan not hitting rocks. I ended up the the top of the motor 0" from the hood, the OEM TB hat actually scuffed the hood inside a bit. I later had to swap out the frame, so I mounted the motor 1/2" lower. Since you have an SYE you can tuck the tail a bit higher, or leave it stock, but I wouldn't go nuts with it. I think the super tummy tuck thing is over rated.

From what I remember, it is 3 degrees.
