? Im running an 8,000 rpm turning, 11.78 second running, 68 340 and a 4 speed.
I also run the original, 40 year old radiator (heavy duty cooling, factory AC). Never gets even a little hot.
Build an efficient and effective cooling system, don't just toss a big radiator at the problem.
Plenty of threads on here over the years about guys with their fancy radiators that won't cool the car because their overall cooling "System", sucked.
