New Cooling/fan question
had close to the same prob, ditched the mp pump for a milodon high volume, high flow thermastst, water wetter, and a dual fan set up with a built on shroud, for streetb use if it was mine i would put a factory fan shroud on , a good aftermarket manual fan and than a electric on the front of the rad for added insurance, that works to i tried it but i wanted those few extra hp so i found the dual fan setup with a shroud from northern radiators, with the setup at top of the page mine runs 190-195 on a hot day on the highway and around195 in traffic not hit 200 yet but may do it in real heavy traffic, either way its a whole lot better than the 205-210 and higher if you don't cut it off or coast prob i used to have, good luck, oh yeah check the cooling info out about the two lines from the blocked off back head ports, i haven't tried that yet but soon8)
