Good water pump but beware

July 22, 2012
This pump does not cover the bypass hole on the passenger side, I tapped it and pluged it with a 3/8 inch bolt to help it run cooler. I would not get the 3/4 inch shaft again, it is a pain to convert the pully and fan along with the spacer to 3/4.
Yes, I recommend this product.

No, on a 1970 if it has OEM pump it should be the long style like part #91015590. Long style measures 7-1/4" from where fan mounts to where pump mounts on block. Short pump measures 5-5/8"

Top threaded connection for heater hose? Hi, could you please confirm the top threaded connection size for the heater hose. You have stated 3/8 NPT which is more like a fuel line size. The stock old pump I have on my 1965 Corvette is more like 3/4" NPT. I presently have a bushing in the stock pump to reduce it to a 1/2" NPT where I have a shutoff valve. Thanks
