In my experience NO. We tested the HiVol Milodon pump in our cooling tests. I do not have the exact model # at the moment. It has a much longer body and moving the hub flange back still won’t make up for the problem. It will make the fan too close to the rad. We had to make all kinds of mounting concessions to make that pump fit.
To make matters worse it does NOT help cooling. Check out our cooling data in the tech tips section of TEAE.org. If you can, send it back. Use a stock water pump. There is NO VALUE to using a high volume water pump in street driving applications, if that is where you are headed. We tested two high vol pumps. Milodon and Stewart neither improved cooling.
