'74 Duster big block conversion
My pistons got lost in route from Summit Racing but they were quick to get another set shipped. While I'm waiting, I worked on the aluminum water pump housing that came off the 440. The water passages were quite a bit smaller and didn't line up with the passages in the block. I used a set of extra gaskets to make templates off the block and opened up the housing passages to match.
I used an MP aluminum water pump that I had. It's on the right compared to inexpensive Chinese aluminum water pump on the left that was in the housing.
Also installed a high flow 160 degree thermostat (right) in place of the stock style (left). Big difference in the passage size. It is also vented for air to pass through when filling the system.
