short or long water pump?
I've searched the threads and can't seem to locate the answer....do SB 350 have a long water pump or short water pump AND how do you tell the difference?

350 chevys had both depending on the application. If the back of the water pump practically touches the timing chain cover it's a short water pump. If there about say 1/4 inch gap between the timing cover and the back of the water pump, it's a long.

Gen 1 small block Corvettes from 1969 forward used a special "short" water pump specifically for Corvettes. The dimensions are slightly different than those of a standard short Chevy water pump. Using a standard short water pump on your Vette will cause your pulleys to be misaligned.

A Corvette water pump is a special application. when ordering a new one, specify make, model and year.
By the way, I have a brand new LONG style if anyone wants / needs it. pm me. free to good home, just pay shipping.

Does anyone make an aluminum water pump for our cars? next time I have mine off I want to replace it with one to save a little weight.
