Need a little help with water pump and pulley's

I'm building a 52 F3 with a SBC engine and I need to know what pulley water pump combo I need. I will have a power steering pump, Alternator, and Vintage air compressor. Do I need a long water pump or short and how many grooves do I need on the crank pulley and water pump pulley. I'm not going to use a expensive bracket system probably separate brackets for each component unless you have any recommendations.
Thanks in advance
Don

SBC can use a set of brackets for either short or long waterpump. Long pump was used on newer SBC engines, and is quite a bit easier to find in the junkyard, so that would be my recommendation.

Do you already have any of the brackets or components? If starting out from scratch, finding a serpentine system from a late 80's or early 90's GM vehicle would work, and you only need to worry about one belt. If you want it to look a little more classic, the three v-belt systems are plentiful in the junkyard.

I am using v belts with a Stewart high flow long waterpump, GM 12si alternator (94 amp upgrade from stock 63 amp 10si), stock GM PS pump, and Vintage air compressor and brackets. I have a 3 groove crankshaft pulley, so it drives the PS pump, alternator and A/C compressor. The alternator and PS belts also run across a two groove pulley on the water pump. This was the stock setup for HD cooling on my '75 SBC, so parts are easy to find. Its designed so that if either the alternator or PS belt breaks, the other belt is still driving the water pump.

Thanks, I have a bare long block with no brackets. Your setup sounds good.

Thanks again for the help

Make sure the heads have the holes for the accessory brackets, not all heads are the same.

Vintage air compressor, suggest you contact them. Find out what bracket they use for that pump.

A side note: an almost lined up pulley system and belt tracking, not going to cut it.

It looks simple and is, but requires the same attention as a front end alignment.

Cheers,

Pep

Vintage Air

All depends on the Clearance you have between the engine and the Radiator Short or long Pump. I would look up the Vintage Air site. I think with Air, Power steering with their stuff you have to go with a short pump.

I bought the 65 El Co in my signature and it had s mish mosh of brackets hacked together. Bought all the Vintage air brackets to make work with the car.. They are sweet. I bought them originally for some early Camel humps with no bolt holes in the front. Found some good Vortecs and went with them instead. The Camel hump brackets work on the Vortecs. Like them as you can see the heads better, cleaner. They were only about 225.00. Pic added
