Serpentine Conversion questions.

Sbc heads went from no bolt holes, to one or two, and finally three, throughout the decades.

Whatever set you get, don't forget to get a reverse rotation water pump to go with it.

YES! Lotsa guys don't know that serp setups spin the pump the other way

My '69 cast dated heads have the three & one bolt holes like the heads on my '81 & '85 dated junk 305's.

The engine in my Grand Prix was missing one of the holes in the passenger side head. I just left that one off and haven't had a problem with it. I used a 88-92 f body setup and the engine was an 82 305.

Awesome I appreciate that.
I was reading an install manual from GM On a z28 forum about serp systems and it noted about how certain heads won’t have all the mounting holes and that you just won’t use that specific bolt. So I think I’ll be headed to the yard in the morning.

Clarmo,

How did you patch this into the G-body AC system? What hoses, condenser and receiver did you use?

I got the information from you guys!
I used Olds 307 Condenser & dryer/accumulator, F-Body lines off the Compressor but had to cut and shorten the discharge line going to the condenser.

I used a 1993 S10 Set up off a 4.3 on my Monte Carlo. While very similar to the F/B Body set up, it is a little narrower but about the same overall height. The only disadvantage to this set up is the upper hose passes through a narrower gap. To compensate, I use upper and lower radiator hoses for a F Body which fit very nicely. When I did this conversion, the location of the alternator went from the passengers side to the drivers side and the compressor took its place. I use a Olds/Buick condenser and had a custom ac line made to keep all of that on one side of the engine bay.

How did you recrimp the end? Did a shop do it for you?

Any picture of this system on the engine by chance? I’d appreciate it as I’ve found a 94 s10 blazer with a vortec v6 with this same setup and just so happens to be factory non ac truck so it has the bypass pulley

We do AC work at my shop. I have a crimping tool.
