Wondering if anyone has a serpentine system on their car and where they got it. Or a place where I can peice all the correct pulleys and brackets for the belt set up for the small block. The ones the previous owner put on them look out of place and have extra nuts acting as spacers etc. Any suggestions or advice is appreciated
. PNs are called out in the book although may not still be available. You'll need to enlarge the water pump pulley ID from 5/8" to 3/4" for the Vette water pump. These are the deep groove underdrive pulleys that were used from the factory on high revving SBCs.
I did this on my 79, and used a setup off of a 92 Camaro. I sourced mine from Ebay - spent less that $150 on the brackets and pulleys. More was spent on the alt, water pump, PS pump, and other additional parts - some of which was required. I didn't track all the costs.
The brackets basically bolted right up. This setup is exactly the smae as the GM serp kit you can buy at Jegs or Summit. In the interest of full disclosure, the GM setup does require some adjustments - so expect some modifications to make all the parts come together. I would still do it again - none of these are big problems, just a list of "to-do's" that you may want to be aware of.
Here is a summary of what I dealt with:
•I switched over to the Camaro power steering pump (not required, I just needed a pump anyway and I got one with the correct pulley) - If you do this, take the inlet fitting from your old PS pump and put it on the new one, so your PS hoses still bolt up. Either steering pump will work. The C3 pump from a 79 will bolt into the Camaro bracket. You have to change the pulley. In my case, I found a pump for a camaro (with the pulley) so I just used that and swapped inlets.
•I had to experiment with water neck and radiator hose combinations to avoid rubbing on the belt. I found one that pointed straight forward from the intake and looked for a suitable hose at a local parts store.
•The lower rad hose is the stock hose, but required trimming and may sit tight against the lower cross member.
•You will have to convert to the later style alternator (CS130 or similar). I used a pre made pigtail from Summit to ease the conversion.
•I used the water pump for a 92 Z28.
•If you have AC, you may need a later pancake compressor; I was not able to convert my stock C3 pancake compressor to a serpentine pulley. Going with a later AC pump may also require an adapter to the older style AC hose block. AC specialists can set you up with an adapter. I called Classic Auto Air and they set me up with a washer/adapter kit that works well. If you don't have AC just run the AC delete pulley.
•The air pump delete pulley is not required, and I didn't use it. If you choose to run it. You may need to clearance the bracket and flip it over. The long straight run between the AC compressor and crank pulley has not given me any problems.
• I also had to reroute the fuel line - if you go with hard lines, will take a little massaging to ensure you don't rub anywhere. I still ran up the front of the block, but you have to work around the brackets so stock line won't work. Not hard, just took a little patience.
•Stock 92 Camaro pulleys all worked and cleared the crossmember - some claim you will need underdrive pulleys. I did not need to go that route.

I used a '89 truck serpentine setup, had the same issues. Hood clearance is 3/4" minimum, paid $100 for the brackets and pulleys.

That looks awesome! I guess I'm going to make a list of parts for a '92 camaro and basically stick to your template and I should be good. I really really appreciate the insite.
I priced everything up on eBay and got this:
New ac compressor(pancake style)
New alternator
New water pump and pulley
Power steering pulley
Ac and ps bracket
And a serpentine belt
Crank pulley
And belt
Cost about $615, not bad considering. Just to choose to shop around or go for like a march system.

Also, I forgot this - if you go the same way I did, and choose not to use the idler pulley below the AC compressor, the belt is not the default stock 92 camaro belt.
You will need a belt that is shorter than stock. My local autozone store let me look at the belts so I picked on that was maybe 4-6 inches inches shorter before I purchased one.
Mine is still a work in progress. I sourced mine from my local pick n pull yard from a 92 caprice. 305 or 350 didnt matter. I took ps pump, alt, ac compressor, all pulleys.
i used the ps pump with my borgeson box, it works great.
alternator is cs130, which i traded core for local shop rebuilt 160 amp, single wire. (My gauges were upgraded to autometer voltmeter)
The right bracket required a little demmeling to get bolt holes to line up without a forced fit. I have aluminum heads, so heads were predrilled.
The water pump is a long pump so it will line up with rest of brackets. I used pulley from caprice. It works great. BUT i had to dremmel left serp bracket to allow water pump to fit. I ordered water pump for 92 caprice, stock pump. This causes a problem because there is no place to run radiator hose. I'll figure that out later. I hope to get an aluminun pump.
i use electric fuel pump, so i ran new hard lines for engine compartment.
ac is not hooked up yet.
Lower hose is stock and cut. Tight fit as mentioned above.
upper hose is a stainless steel 24 inch after market one. I will probably switch to a swivel neck, hard 90 pipe with rubber fittings for neck and upper radiator connection.
belt is rerouted due to no smog pump. I did a search on serp belt and found other sites that showed how to reroute belt and what size to get. It looks just like what cooper9811 did in photo above.
good luck! Changing belts with a single 3/8 ratchet and about 5 minutes is sweeeet! So is no squeels at any rpm.

If I remember correctly I bought 1 pulley, then could not find similar style to match so I had a guy at a shop I worked at wire out the profile I wanted & then machined the last 2 to match the existing.
I just recently did my engine, and I didn't want to go through all the research to find all the parts, so I went with the March system, for the Corvette. I really like it, easy to install, and fits, even with my Lincoln Mark VIII 2 speed fan.
Do you have a part number for that upper rad. hose ? I'm using a 1990 corvette system and could use some help with that .
For mine, I went to a local autozone and they let me look at rad hoses till I found one that looked like it would route correctly - so unfortunately, I don't have the part number.
That's the tradeoff when assembling from "found" parts - I love doing that, but you have to be prepared to look around, and possible modify things from time to time.
I was going for clean and functional - I thought about the March stuff, it looks great - but the GM system just suits my style a bit more. Plus the system itself is cheap if bought used. The majority of the expense was in the new AC compressor and alternator.

Pulleys... Where to start?
