i picked up a 91 gta roller and i have a guy whos got a couple of 350 blocks for sale and 2 of them are 010 blocks. i know those were late 60's-70's blocks. my question is do they have provisions for the oil pressure switch and knock sensors?

 

Yes.

 

for sure they do? just checking because i looked at them the other night but it was too dark for me to see anything

 

The knock sensor uses the block drain hole and they all have the 1/8" pipe thread by the distributor for the OP gauge.

 

The knock sensor was designed to fit the hole, not the other way around.

 

ok is the knock sensor hole always on right right hand side of the block then? no matter what year?

 

The holes are on both sides of the block.
