Having the engine rebuilt. 454, 60 over 10 to 1. Radiator is a 4 core. Did not have heating issues prior to re-doing the engine. Do I go with a Stock pump or a high volume aluminum Pump? suggestions.

 

Thanks , Alan

Alan, I basically just did the same build on my now 496 and I went with a Weiand aluminum pump. Upgraded from a Procomp aluminum though they both gave me no issues in cooling the Weiand definately fit much better. The Procomp had to be ground off a little around the timing chain cover to fit properly.

Here's a basic picture of a short and long water pump...

As you can see the long style (which came stock on our cars) will have all the mounting points for accessories, the short has none.

 

My 502 came with a short style and I removed it and put my factory original one on so I could mount everything back up...painted it silver first to make it look more like aluminum though. Besides being very heavy it has worked perfectly fine, eventually I will replace it to shed some weight.
