Early style sb water pumps

Think you're missing the point bro, I'm not trying to change a bunch of stuff. I'm building a motor from scratch and when it comes to buying stuff I would have rather had the option of buying an aluminum early style pump. That was the point I was trying to make how about them in the first place, that there is simply no one who makes the early style in aluminum.

Not missing the point, That is how much weight difference there is between water pumps. Don't hold your breath waiting for someone to cast that housing in aluminum.
