Can headers help reduce engine temps.

I'm going to try the timing again.....

I had an old suburban with a 350 that ran great out here. When the water pump went I put on a high flow pump on it I think flowkooler. I ran into the same temps you describe. I put a stock pump back on and everything was fine. All I could figure is the hi flow was either moving the water too fast or causing an issue where the stat wasnt opening.

SteveL - I also have the Flowkooler. I've heard of this occurring. I installed mine after the heating began, no change.

[ , and smaller lower pulley....whew! ]

You want the largest lower pulley that will fit with the smallest water pump pulley.

If you run v-belts then BC has the smallest wp pulley and the largest crank pulley that will fit.
