Carburetor choice and Alternator Bracket

Hi everyone,

Newbie question here... first car with a carb for me...

I just bought an old Jeep with a Chevy 327 swap. Engine number says it's a 1968 327.
The carburetor (oviously not stock) is a Qjet #17087245 that was used on Dodge HD trucks (85 to 88).

Is it ok to use a carb designed for a 360 engine on a 327?

2nd question is regarding alternator position:

Is this setup a custom one? because I'm not able to ajust belt tension...alternator is touching valve cover... see picture:
