Running out of bolt-ons, so I figured I'd give an E-water pump a try. I ordered one off Ebay that had been used once (according to the ad) on a Dyno run and they changed plans and went with a different engine. Anyway, I got a decent deal on it, so we'll see how it works. He said he gained 17hp from it on a 434. Not a bad little jump if I get in the same vicinity.
