I have not skimped on the $$$ The car currently has the factory Plastic tank radiator. The car will have the A/C and I don't want any over heating problems. I see couple different MFG of aluminum radiators but I don't have a clue where to begin. I am planning on running the stock fan and shrouding. The car will not be at the drag strip every weekend Just driving in the country Kicking it and also Cruising in town It gets pretty Hot here in Michigan in the summer and I don't want any Problems. Thanks for the advise
