Do the serpentine belt and v-belt 305s have the same mounting holes for accessories?
I have a 305 (86) with the v-belt setup and scored cylinders. I found a guy selling a 305 from an 88 firebird, but it was set up for the serpentine belt (and doesn't include any of the belt driven accessories from the seller)

can I take my v-belt setup (alternator, smog pump, power steering, water pump) and bolt it to the front of this later 305 block?

The passenger upper inner hole is missing. Cast iron heads are thin. Just make sure it’s braced. If you use serp. Or the v belt setup bolts right on.

so that's just the back of the long alternator bolt?

The alt changes sides on serpentine, it’s by the water port if using the serpentine bracket a/c compressor side.

Yeah I guess my question is can I use the v-belt brackets and accessories on a block that originally had the serpentine belt setup.
