Default Engine comp grounds

Can anyone tell me how many grounds are in the engine compartment? I just put my engine back in and a couple electrical issue. Mainly tach and alt, they appear to be hooked up correctly. I noticed 1 ground under the fuel pump I missed (anyone know what it is to) and want to double check there aren't any others I might have missed.

Block grounds to the frame. Starter harness might ground to the tranny. Do you have the assembly instruction manual (AIM)? The AIM shows the factory grounds.

Another vote for buying the hard copy paper AIMs (my personal favorites).

What model year? If I have the AIM, I'll check tonight.

Didn't the late 70's/80's cars have a ground up at the {plastic} distributor shield and over to the air cleaner? (I don't have one; just seem to remember something up in that area.)
