1930u Getting the right early 70's stance?

Here's a few pics. taken today. I'm pretty happy with the way it looks but the engine is raked down in the rear a little more than I care for. I have adjustment slots on the bell housing mounts so I can raise it up no problem. Just thought I'd get a few opinions from the group.

stance

You want the engine and trans to be in direct straight line with the rearend yoke. The stance is fine. You might get the radiator back behind the front axle.

The biggest concern I would have with the amount of engine tilt would be getting a decent pinion angle.

What the other guys have said about the proper angle relationships is true.
With that being said, you are building one sweet ride!
That is going to be wicked when you are done!

The engine should be set up so that the carb mounting surface of the intake manifold is level from front to rear and from side to side. This will allow the carb bowls to fill correctly and function correctly. It will also yield the crankshaft centerline down at the rear approximately 3-4 degrees. That is a common down angle for the engine/trans and will allow the u-joint to perform as designed without premature wear or binding.

At the present, looking at the photo's above, it appears that the crank centerline is down at the rear closer to 6 degrees. That would be too much for street use. It can be corrected by either lowering the front of the engine at the engine mounts or raising the rear at the trans mount.

For street use the centerline of the pinion shaft of the rear axle carrier should be up the same number of degrees that the crankshaft centerline is down. i.e. engine down 3-4 degrees with the trans up 3-4 degrees.

The end results should have the engine crankshaft centerline parallel to the pinion shaft centerline looking from the side and from above.

For drag strip only the pinion shaft centerline of the rear axle carrier should be down to allow for the tendency of the rear axle to rotate up when under hard acceleration.

Just for a visual comparison. Here is a pic of a modified version of your coupe. The engine has been tilted up at the rear three degrees from where you show it in your original photo. The engine sits with the carb bases level to the ground in this pic. I didn't fix the fence rail in the background so you can see the changes. Left click for a larger view.

Second pic is where the bottom of the tires are level with each other (Original pic tilted 2 degrees up at the rear and the engine has been tilted up an additional 2 degrees at the rear).

Thanks Frisco. It should work out fine. I have plenty of adjustment front and back.
