440 Source Water Pump

I put a 440 source w/p in the Bird when I built the engine. Does anyone no what kind of pump it is...standard flow/high volume/high flow/junk? It seems to work fine.

Its a hi-flow. I like that impeller design the best. I have a nippon milodon 6 blade waterwheel that I had to spot weld on the shaft because it was loose. Its a backup, dust collector now.

Sorry to hi-jack, but lets expand.... How much cooling help can you expect from a high-flow pump over a stock replacement pump?
