Serpentine system

How many of you guys out there are running a stock serpentine setup on your SBC? I really like the looks of the chrome or billet brackets and pulleys in serpentine systems that I see in a lot of cars but just can't justify that kind of money ($1000-$2000) in a daily driver. I know the stock serpentine setup looks a little clunky but with a little paint and/or polish I think it could look pretty good.

That`s what I do, take a complete system off a junk yard vehicle, have it shot blasted so it comes completely clean and stripped of paint, repaint them to the desired color, and the brackets coat them with clear so it has that nice cast finish. I like how the end result is and it`s so much easier. But you must get the complete system off one engine, if you try to mix and match it don`t work too well as many sizes and lenths are out there. also remember if the water pump pulley is smooth you must use a reverse flow water pump.
Another nice thing is it swaps the alternator to the drivers side and the A/C compressor to the passengers side so you can use much shorter hoses and it looks alot neater. I don`t know what they were thinking with the compressor on the drivers side with 2 mile long hoses. I have a link that will give you more info, if you want it just ask.

I think you already have it from a previous thread Kul, but I`ll post it anyways.

A link on how to use a small block serpentine on a big block chevy:
http://www.fidnet.com/~harleyms/serpentine%20page.htm
When I went to a serpentine system I got it off a 92 Camaro with a TBI 305, I installed it in a Olds Cutlass supreme that I had dropped a vortec 350 in. I picked up a A/C dryer for a 92 camaro and bolted it on my cutlass, then used the Camaro`s A/C hoses and compressor. Another nice benefit I was able to use a much higher output new style alternator, The wiring harness is different so the solution is to order a adapter which just plugs in to the old harness, summit and others offer it and it costs around $20. Lastly if your getting the system off a junk yard car make sure you take a power steering pulley puller with you if you don`t plan to use the power steering pump, I already had one so I didn`t need theres plus it would just drive up the cost more, If I recall correctly the older V belt pump has a different slant to it so it won`t work on the serpentine, but I maybe mistaken. The Corvette serpentine system uses a short water pump design like the old small blocks from the 50`s and 60`s so it too must be used in a set. I think I paid $100 for the whole set from the junkyard. I used to have a better link that gave much better detail on converting any small block over and it even gave the belt size, but I lost it when I had to reinstall windows. Hope this helps. One last edit, if you plan to use a clutch fan or flex fan it too has to be reverse rotation, summit carries the reverse fan for around $35. I think some of the early systems used a ribbed water pump pulley, and these used standard rotation water pumps and fans.

You're right. I have it saved. I have an 86 IROC I need to do a few upgrades on and a later model serpentine is one of them. THANKS FOR WAKING ME UP...

Thanks for the links Doublevisioin, it's great info. I'm definitely going to the boneyard and pick up the system. The one thing that concerns me is the compatability of the after market AC systems (Vintage Air, Southern Air,etc.) with the AC compressor from the stock GM serpentine drive. It looks like I might need to make a call to the vendors before going too far.
