More of a road race question,but Im curious as to which water pump most of you guys are using in your small
blocks,six or eight blade.Have you tested with both?What are average coolant
temps during track sessions,and what is a comfortable or acceptable temp?During
a hard session I will see temps of 210-215deg.

Im currently running an eight blade and noticed when I installed a Howe
alluminum rad(cross flow) coolant temps were up from previous rad(dessert cooler
3 pass down flow) on the highway.I removed thermostat and installed fixed
restrictor and temps came down to normal.Im wondering if I should try the six
blade pump to slow flow down.

thanx
