I believe it's a 305 SBC, it's a 305 4BBL. The power steering pump is on the other side of the engine I believe (going by the PS fluid reservoir).
Looks like I'll be removing the pully from the air pump, as one of the bolts is half hidden by it. Thanks for the advice on checking a reman, I'll be sure to do that
.
For the belts, should I go with a name brand like Dayco, or would a NAPA work too? The V-belts were replaced at one time, and are all NAPA.
