okay, I will give MY advice, but if someone disagrees with me WITHOUT a better idea of reason I will be done posting.

The motor need to be level side to side...with that said I wouldn't be too bent out of shape if the left side (drivers side) was a touch lower.....say 1 degree.....the reason for this is the inside (left) of the motor tends to run a little if you had a little extra fuel running down hill to the left side I would not cry. LEVEL IS PERFERED THOUGH.

On front to back .......I like mine to run up hill at the front 2 degrees.....and fuel is already running back in the intake so the reason is for drive-line angle..keep in mind MOST people set the car up with rake....the rear is the chassis is not putting the motor in tilting back will mean the motor is level when set-up to go racing........

this all assumes you run the chassis level
when you are set-up to go racing.....

If you put tilt in the car.....meaning you run the right side higher than the left I would NOT consider letting the left side of the motor hang down..........if the left side is lower when chassis is sitting level and then you put tilt in the car you will end up with a fuel disribution problem. some plugs will be lean and some will be carbon.............

try to keep it level side to side and front to rear........

4 degrees down in back measured on the valve cover, which is probably 0 degrees on the intake carb mounting flange. I use a set-up block when I install motor mounts, and just use the top of the block to go by.

I agree with Tilley88 4 to 4.5 deg is ideal will give you the best drive line angle. And mount engine as low as you possibly can.
