Technical SBC 350 Pulley setup for alternator only

Hey everyone, looking for a little guidance on this. I have a 1992 SBC 350 TBI that I am changing the intake and going with a carb. My question is does anyone have a setup they have used to go with just a alternator? The 34 Dodge Sedan I am building has manual brakes and manual steering so I only need a alternator. The current water pump on this year 350 has a reverse flow water pump due to the serpentine setup so I would need to change that as well. My plans are to change to a vbelt by changing the pulleys.

Anyone know of what I might be able to use to cheaply change this to a vbelt, alternator only system? Thanks in advance for any advice or recommendations.

 

Reverse the rat rod thing as well. Then I’ll have an answer.

 

Not sure I follow this lol but it's a 1934 Dodge 4 door that has been cut down to a 2 door from what we can gather. Was built in 1967 and has changed hands several times. Fun little toy though.

 

Not here you're not!

 

Lol my mistake, edited the initial post. Working on a 1934 Dodge Sedan.

 

People are dicks sometimes, instead of just helping.
All you need is something like this or hit your local junkyard if they have cars in the 70's and down.

You need to determine what works best for you, either short waterpump or long, they have different pulleys, location of the alternator and fan to radiator clearance usually dictates which pump you're going to need. A short pump puts the alternator behind the leading edge of the block so it sticks out further from the engine and takes a longer belt, long pump you can put the alternator in front of the engine block and have a little tighter engine bay.

 

I would run a "long" water pump (came factory on a LOT of vehicles ... it is the most common one) then find the factory style alternator bracket (pictured below) then buy water pump and crank pulleys to match. This puts the alternator on the passenger side. I initially ran a "short" water pump and an aftermarket alternator bracket and pulleys. The aftermarket bracket put the alternator on the drivers side, basically above the valve cover and I ended up with trouble due to very limited belt contact on the water pump pulley (poor design of the aftermarket bracket that put the alternator so high up). In order to solve the belt contact issue, I ended up buying double-row pulleys for the crank and water pump and then ran two belts on the engine. First belt: crank/water pump/alt. Second belt: crank and water pump only (you need to find the perfect length belt because there is no adjusting a belt that only runs off crank and water pump). In the end I removed the short pump, bracketry and pulleys and went with factory "long pump" brackets and pulleys. I was much happier with the long pump. It appears that all the needed brackets and pulleys are available from the aftermarket if you aren't able to find factory stuff.

 

Order a water pump for a 78 Camaro (305 or 350) and you'll get a long pump that spins in the correct direction IF you are wanting and have room for the long pump.

 

Thank you so much! That was exactly the advice I was needing. I should've also mentioned I will be running a electrical fan as well. Thank you again!

 

Thank you very much for the advice. I will be heading to the junkyard this Sunday and maybe I will get lucky! Thank you again!

 

So with the "long pump" pulley setup did you still have to run two belts or did you just run one? I noticed I can buy a single groove water pump pulley or a two groove one for the long pump style.

 

You can run one belt. There are single groove deep lower pulley’s that the factory used on non power steering vehicles.

 

You just need one belt. Dual belts require a matched set.

Be crank pulley, water pump and alternator.

 

Can you change the serpentine pulley on the alternator over to a V groove ???

 

Should be able to ,they mount the same AFAIK ..

 

Thank you all again for your help and advice, it was greatly appreciated. First time working with a SBC so it's been fun learning the ins and outs. Thanks again and hopefully this thread might help out the next fella who needs this advice.

 

Hes not talking about dual matching belts. Hes talking two separate belts of different lengths for different accessories.

 

Okay, then you know more about what he’s doing than I do

Edit: let me explain. With only one adjustable accessory, the only possible way to run two belts would be to have dual belt pulleys on the water pump, crank and alternator pulley. This would require a matched set of belts.

 

Dang it's hard to jack a photo of a small block with a plain old stock style alternator bracket on it when you are hunting one
The number of grooves in the pulley don't matter but it would look better if you just had single groove pulleys rather than naked grooves. The bracket on this engine is chrome but it is pretty much the same one that is on 90% of small blocks with long water pumps. Get the long bolt and spacer that goes behind the alterna tor with it. Pulley is just take one off and put the other on. Any mid 70's chevy with a small block and long pump should have what you need if it is still on the engine.

 

Here is my set up with long water pump.

 

If you choose a short water pump, here are the part #s for the water pump pully and crank pulley. The crank pulley will be a double groove, but it will work fine. Order an alternator bracket for a 67-68 camaro and then you are all set.

 

Reading this I realize what a disadvantage guys are at today , no never ending supply of good , clean factory setups in the junkyards , that is with what junkyards are left !

I have a 1990 SBC 350 in my '39 and went with Dart SHP aluminum heads, an Edelbrock intake, and Quick Fuel carb. I use a standard flow short water pump to ensure good clearance, but a long would have worked, as I ended up putting a 1" aluminum spacer under the fan once it was all done. I used a standard length water pump pulley, and a single lower pulley. For the alternator I got an adjustable chrome bracket from Summit that mounts over the #1 header tube, and can be moved forward or rearward to align with my pulleys. It was only about $12, and I've used these alternator brackets on numerous builds.
Seems like they've really gone up recently!

I’d run a setup like this i

Not necessarily, you run one belt round alternator, water pump and crank pulley and the second belt round water pump and crank pulley only.

 

How do you adjust belt tension for water pump/crank pulley ?

 

Nothing " traditional" about that !

 

You put the correct sized belt over both pulleys before you bolt the pulley to the water pump. It was the standard set up on base Corvettes in 1968/9.
