Speedway Water Pumps

[jrvariel48]

Does anyone have the 48-52 truck water pumps on an early block??
There's a hole on top of the pump that lines up with a water hole on the 8 BA block. The 59 blocks don't have this.
Question is what do I do with this hole on my 59 block?? They told me they would fit a 1946 block but said nothing of these holes. Am I missing something?
Thanks,
Joe

You can just put a plug in the hole without any problems going forward. I've seen it done before on a 59A with an 8BA cam and timing cover.

For over 20 years in my 49 F1 I ran an 81A motor with the water pumps you mention. Plugged them up and never had any issues.

What did you use to plug them up?
Thanks

If your talking about heater hose hole. I just got the same water pumps from Carpenter, for my 52 F1. They came with a screw in plug. The plug would be necessary if you don't have a heater. I'm sure you could get same from local hardware store.

I do have a question. Are you saying a later model water pump (ie: 52 f1 to 39 car) can be used on a earlier block? Many folks could avoid cutting hole in hose for heater hose?

adileo this hole is at the top of the water pump and faces the block. On an 8BA block, this hole matches up with a water port. On a 59 block, there is no water hole to match up with. I was able to thread the hole with a 1/4" NPT tap and put a threaded plug into it. Problem solve. I had to use these pumps because the pulley is out further from the block that the earlier pumps. This set up is for the blower I'm installing. The pulley that's included with the blower has a special double pulley to install. The 1st pulley that's closest to the block, is a 6 rib micro V-belt to drive the blower. The 2nd pulley will drive the water pumps and alternator.

Just what was at hand: a close fit metal stud with sealant. One leaked a little so I added more sealant ...
