I know that carbureted small block Ford engines need to be angled 4 degrees downward towards the back of the car. Does this hold true for the 4.6L? I am fabbing motor mounts and need to set the angle...

that is interesting. where did you hear that and what is the reasoning for the tilt. I could see for the oil but that would be 0 degrees tilt.

If you look at the top plane of an intake manifold (where the carburetor mounts) for a SB Ford you'll notice that it's angled down toward the front 4 degrees. This is to compensate for the 4 degree down/back angle of the engine, keeping the carb level. I figured that the 4 degree down/back of the engine was to set pinion angle and the carb mount had to compensate so the carb would stay level.

I figured this wouldn't be an issue for a fuel injected car until I read somewhere that it was.
Ideas?

I wouldn't think it would be an issue for the engine to run as it would be more of an issue of aligning the driveline correctly.

My EFI 5.0 engine is tilted back very slightly, so i guess that could be the 4 degrees you are talking about. You just want the driveshaft low and as straight as possible in relation to the rear end. If you were to use drop motor mounts, the engine would be closer to level.
