I recently purchased a 88-92 camaro OEM serpentine system from www.tacreationsusa.com
They offer a "conversion" for $200 + shipping that will give you almost everything you need to convert your V belt system to serpentine. You MUST have accessory holes in the front of your heads though. Included in the package is the alternator, power steering pump, A/C compressor, smog pump, water pump and all the bolts.
Some things to consider are that a serp system turns in reverse of a standard water pump so you either have to get a reverse pitch mechanical fan or go electric. You have to purchase a water pump from a 88 or so chevy truck (305) because the one supplied does not have a connection for the heater hose. I didn't want to put a used water pump on my newer engine so I am getting one from a local part store ($25) and using the supplied one as the core.
The alternator supplied with the kit is a "CS" style, you can either go to the Tech part of this site and there is an article that will tell you how to convert your current wiring or you can go to American Autowire www.factoryfit.com
and they can sell you a conversion harness to convert your harness without cutting your harness (for about $15).
I talked to the tech reps at vintage air and they told me that the OEM a/c compressor puts out too much head pressure for their system but noone has complained about problems, but I got a a/c delete pulley from the dealer because I don't currently have air. I think the next issue of Popular Hot Rodding is going to have an article about Mark Steilow's new car using this same kind of belt system and how he used spacers to put in a vintage air compreesor (Sanden style).
I was told the smog pump could not be removed because it was part of the bracket integrity, but when I got the brackets I found out that I could fabricate a spacer to accomodate for it.
You will need to get a serp belt #968k6 to make up for the smog pump removed or purchase a smog pump delete pulley (from the dealer) to use the original belt.
A/C delete pulley GM #10055890 ($59)
Smog pump delete pulley GM #10186167 ($54)
You can more than likely sell the A/C and smog pump on ebay or locally and try to recoup some of the original price that way.
I just wanted to let everyone know out their who wanted to think converting to a serp system but don't have $500 or so to spend on a March or Zoops system. I have nothing against those companies but my budget doesn't allow my to spend that much money
This configuration puts the alternator on the drivers side and the A/C compressor on the passenger's side and allows you to use all GM parts.
I did alot of research and here is one of the web sites that I found that helps in the conversion (even though it is on third gen car, the basics are still the same) http://sethirdgen.org/serpentine.htm
If anyone has any questions email me and I will try to help.
