Do you mean in the car? If so what year, brand car and motor and what type of use?

believe 3 degrees to be normal. basically carb pad level with engine in the chassis and car on the ground is desirable. of course this may not be doable all the time in a race prepped chassis. having intake manifolds with no carb angle designed into them makes it difficult or next to impossible for the carb to sit level. edelbrock catalogs have some interesting crab pad angle specs. would be good reference.

3* from what I recall. It doesn’t have be exact.
It really doesn't matter whether you win or lose… as long as you look good doing it!

Well you should do some figuring before you go to town mounting it. What rear suspension? That matters for pinion angle and where the front ends up.
When I did my car last year I set it up with the rear at ride height, pointed the crank c/l right at the pinion. Made both 0 and 0 Then when the car was done I sent my pinion angle. 1-2 degrees down. (4 link)

Is there a preferred degree to tilt the engine back thanks If you are working on something that is mostly stock then use the factory mounts so everything fits. If you are building a chassis from the ground up then do whatever works.

Stock front end, back half car? Putting it in on plates? OE steering?
They're ~ 3 degrees from the factory. This creates some less than perfect compromises if it's a backhalf/big tire car with the rear housing moved up in the chassis.
Best answer is lower the engine as much as you can, and point the engine/trans C/L at the rear yoke C/L with the rear at ride height.
Yes, you'll have to build headers and OE steering will limit what you can do.
If you can get the driveline straight from the front of the crank to the rear ujoint and dial in a bit of negative pinion angle, you'll be golden.
If you manage to get the front of the crank at the same height as the rear ujoint, it will all be level.

If the results don't match the theory, change the theory.

Easiest way for me was the carb spacers. logical choice when using something like a victor intake or any other race type intake with no carb angle.

Optimally you want to have the engine when mounted (crank centerline) parallel to the pinion centerline at a height that creates a 2deg angle from crank Centerline to Drive shaft and a 2 deg angle from drive shaft to pinion centerline. One angle being positive and the other being negative.
