AK71CutlassS

Looking for suggestions on a water pump for my 455 build. Currently have a 1971 Cutlass S with a 350 non AC. I beleive its a 5.09 length pump. Thanks in advance

Get a new replacement pump for your 350 if you plan on using the pulleys and accessories from it.

what is the best pump for a non AC 350 I can get that is 5.09

I don't know that there really is a better choice.

No different brands. Aftermarket?

The factory water pumps get the job done. If you keep it stock the non AC water pump casting number is 408328 for 1971-72. It is the same part number for 350 and 455.

I have milodon aluminum water pump on mine.

All of the aftermarket aluminum pumps I found were listed as 6" length pumps.

Yeah me as well. If I could find a aftermarket pump 5.09 length I'd get it. Not finding one anywhere

Well -- i guess youre on your own -- here is a chart that lists all 3 different lengths being a use on 1971 350 engines. Actually i have not been able to fine the exact shaft length for the 130-1260 today - so you need to verify it is the one that will match your pulleys.
i actually i am using a pulley set off a 73 350 on this pump on my 400 in a 67.

I just found where the GMB 130-1260AL pump has hub height of 5.95" so it wont work on your motor if you need the 5.09 one -- unless you get a set of pulleys that match it?
