Question

I'm in the process of trying to scrounge up some brackets for my impending power steering conversion. Everyone wants to know if I have a long water pump or short one. Considering this is my first big block, I'm not sure which one I have currently. Aside from getting the #'s off the waterpump, what's an easy way to determine short or long? I've got everything I need except for a few brackets, suggestions anyone? KZ

Hey John,

Is your alternator on the drivers side or passengers?

Drivers side = Short
Passengers side = Long

I have all the pulleys for the long if you are lacking any.

Kel,
My alternator is on the passenger side. You've got some brackets, eh? If you start looking for them now, maybe I can come pick them up come springtime...... I'd hate for you to have to go through another scavenger hunt, just for me......I've got one bracket, the big one that holds the pump, I just need the adjusting bracket. Let me know if you can find them. Thanks.........KZ

Sorry kz,

I don't have the brackets, just the pulleys (and I know exactly where they are )

You have a long water pump though if the alt is on the pass side.

Have you looked at trucks in the junkyards? Long water pump big blocks were a very standard setup for a long time.

The year break on all this long pump, short pump thing was 68. 67 and 68 big blocks had SHORT water pumps with alt. on the Driver's side. 69 BB had LONG water pumps and the alt. on the passenger side.

Now here's the deal in my own 69 big block. I USE a 68 style shorty water pump and 68 brackets to put the alt. on the driver's side. WHY you ask???? Well, because I wanted my Vintage Air compressor to be on the PASSENGER side so I wouldn't have to run those ugly AC hoses all over my engine compartment.

Secondly, superchargers need to be mounted on the driver's side and it is much easier to move an alt. around than it is a AC compressor. (And no, I don't have a supercharger because I currently prefer NO2 but I am always looking ahead towards new toy options).

The only problem I found with this 68 combo is that you need to use a deep groove alt. pulley to keep from throwing off the belt at high RPMS. The 69 setup utilizes a much shorter alt. belt because of the bracket position on the pass. side and this is not as much of a issue with this combo.

JimM hit the nail on the head.

look in big truck at your local junk yard. now i am talking high cube, cab overs, what not(not the average 1/2 ton standard truck). basically they share many parts with the chevy trucks(1/2 ton) like the doors and stuff, but sometimes you may find big blocks under the hood, and not the desiel motors. i lifted the hood on a 70 something big truck and staring out at me was a 454 long pump with the Holley double pumper still on it. looked like the truck could still run. most of these trucks are loke car haulers, tow trucks, or flat bed dump trucks.

good luck, Jesse
