street rod build

I'm putting a fairly serious motor in a street rod for a customer. Its a 1940 chevy truck thats getting a 383 SBC with about 550 hp. Its got no mounts in it whatsoever and i just finished welding in a Heidts mustang II style front end. Now i'm mounting the motor. To me it seems logical that the engine / tranny should be level with the frame. Like level the frame on stands, then install the motor / tranny level as well. I've never done anything quite like this before. The customer suggested that when the truck goes down the road the frame won't be level (true) but the engine should be so therefore the engine / tranny should be angled down when the frame is level. Anyone have any expereience with this ?
thanks

Level off the carb pad of the intake.

I've always wondered about that- Thanks, Jack.

Out of ignorance, I mounted the engine in my hotrod level with the frame, and the frame is level with the ground. Consequently, the carb is tilted forward a few degrees. I've heard that you can also have some oiling issues when the back of the engine isn't lower than the front, but I've had no problems with my setup, and I've gone 18000 miles or so.
Mounting the engine level in the frame lets you get the engine as low as possible, but I don't think that is a big concern for a street rod.
