I was hoping for some help in converting to a 2 v-belt upper water pump pulley. My old set-up had 3 grooves and the middle was for the smog pump. I "lost" my smog pump so I only need the two. Summit doesn't have a 84 Camaro replacement. I am going to try to fabricate something but if anyone can give some advice ahead of time that would be great. I have also condered removing the A/C but I think this is the pulley colsest to the block.

 

was in a similar position with a 88 i built a 355 for. it's hard to get what you have and what you find to work. i ended up geting every pully and bracket off a 350 truck. i'd guess a ny 305, 350, 4.3 or 3.8 would work as a donner.
