Well you've confirmed that you have sufficient pull through the grille, I would still replace the fan with a solid/fixed blade,.... your seals are in place, you know the radiator core
has been redone,...but have you confirmed a spring in the lower hose?, just squeeze it to confirm it can't collapse,....again I'll recommend the ZEREX G-05 antifreeze, 50/50 freeze/water mix, with 8-10 Oz of REDLINE WATER WETTER (Autozone)....this antifreeze mix alone was worth an easy 15-20 degrees lower running temp in my Daytona, which always ran 210-230 in slow moving traffic, so I more than know your woes of running hot,.....straight water with water wetter is the most effective cooling mix,....But antifreeze added has the ability to raise the boiling temp of the fluid, combined with water wetter helps to eliminate steam pockets that develope in the cooling system/engine when it reaches operating temps...


What is the initial timing of the engine?
