What is this that I hear about using an electric motor to run your water pump and runing it backwards. Cooling your heads first then your block. I understand it will drop your temp 15%. Fact or Fiction?

I seriously am doubting that one. If you think about the fin design on the impeller there is no way it is going to efficiently flow backwards. Along the same lines a boat prop will go backwards but not for speed.

If you look at some of the GM's, they're running a reverse flow system. If does work very well.
BUT, unless the electric pump is built for street use (not the ones in the Summit/Jegs catalogs) don't use them. (You'd also have to redesign the T'Stat location - figure some way to reverse it.)
If you want a little bit extra cooling and flow from the cooling system, invest in a 180 T'Stat and a Flowkooler water pump for the SB Mopar. (They have a part for the Magnum engines.)

I had a '94 LT1 with the reverse cooling. I don't think you want to make all the changes necessary to make it work on your truck. To get full benefit you need aluminum heads amoung other things. I bought '98 with the LS1. It is not reverse cooled. I guess GM thought it was too much trouble for the gains.
