I would like to know if there is a serp system out there that will allow you to use a stock 73 water pump and mechanical fan. I would be able to switch to a serp system, but my racing class mandates i must keep the stock water pump and must have the mechanical fan. I can change out pulleys and brackets, but not the equipment. Oh yea, i must keep the stock power steering pump also. Any ideas?
A serp belt system from a late 80's GM truck could work. The pump will look the same just be a little differant height and they use a mech fan.

Yea some do and some don't.
All the reverse alum. ones I see don't have any as the F-Body's did not need them. I'm going to go by advance and see if the one they stock has it or not.

I believe the truck systems may cause the accessories or tensioner to not fit below the stock hood.

I do not have AC and the heater core is bypassed. All i need the belt to go around is the crank, water pump, alternator and power steering pump. I must keep the engine driven fan. I am allowed to run an electric fan in addition to the mech fan, but that really doesn't cool the car any better.

I have the GM Performance Parts Catalog Serpentine kit on my ZZ4 which is in my 68.
For a serpentine system for your C3, this is by far the most economical.
For extra bucks, toss the Serpentine kit cast iron water pump for an Edelbrock aluminum pump and get some March under drive pulleys.

I decided NOT to go with the GMPP serpentine for my '69 due to someone at the local Chevy dealership writing in the parts catalog in big letters "will not fit under the stock corvette hood." I went with and '84 '89 combo setup. I still need to figure out an AIR pump delete.
