I've had much better success with a stock pump and Monza pulleys then with expensive HiPo water pumps and common pulleys in my Vega's. The pulleys help a LOT in slow traffic and at an idle. They're are a ton of variables when it comes to cooling as we all know.

Also, I didn't read the OP's post correctly. I didn't realize he was talking about swapping BB and SB pulleys...my bad.
