Yah, "high flow" is their description. It's high flow compared to their under drive pulley that usually comes in the kit. I was just trying to give him an option since all of his other pulleys are aluminum. If the problem ends up being the fan, maybe the 6.4" pulley would work?
Ya, Thanks for that info. If the weather ever warms up around here, I will give a report on the 7.25 OEM steel crank pulley that I have on there right now. I would like to stick with all aluminum pulleys, so if the 7.25 works real good, I might try going to the 6.4 aluminum pulley you mentioned.
As a side note, I actually had to trim about 1/32" off the O.D. of the steel pulley I am using to keep it from hitting my existing water pump pulley. I should know pretty quick if the water pump bearing ever starts to fail.
