Tried two different 22" radiators, with a factory shroud and 7 blade clutch fan It's just not gonna do it. I have played with timing and A/F ratio, so lets just leave that out of the equation.
I am looking at options, could run a two row 26"
factory radiator with shroud and new fan clutch or go Champion 26" with their fans and shroud, or Champion (3-4 row) with late model fan/shroud.
I don't have cash to trial and error this, so what is working for you?
