i have run a gm 400sbc that was built to the hill . blue printed / balanced / knife edged crank and good cam and heads . use to be in a k10 with 1ton axles / 4.10 gear and 38" tires with th350 trans .

i tryed all combos of 3 core tall rad with and with out shroud and flex fan / clutch fan . she always did 210 98% the time .

most guys going in to the 4 core world tend to find its to much i have read .

might be a easy test and fix with a pusher fan infront of the rad on a temp switch in the intake by the t-stat .

but i understand were your coming from .
