Thank you for the advice and thanks to one forum member in particular too who i have greatest respect for, whose guided and helped me a lot through this build process. I went with everyone's advice and went the mechanical pump route. So my next question i have is this: My Dad and I question that we will have the clearance needed when we drop motor, to run a clutch fan with the set up on drag car as the aftermarket radiator is tilted. So i asked a friend of mine if running the mech pump without clutch fan/blade fan, with radiator and electric fan would give me the cooling I need. He stated, yes if i have an adequate radiator and electric fan, I would be fine. I have no reason to doubt him but also like to hear what other people who are smarter than me have to say. Any thoughts on this? Thanks!
