How much heat you build leaving in high. Asking because thinking high gear with A/fuel setup might work pretty well. Will not be 2700.Well not unless I get bigger pump and hotter mag,right now running msd mag 12, I could dbl up and run two mag twelves. I have two and dual magt base. I think high gear leave with higher gear in rear might workout with bigger pump. I haqve a 13 gpm and a 19 gpm pump on shelf.
