SBC 350 even before i added the weiand supercharger my car overheats not standing still but the faster i drive shouldnt it overheat standing still? You would think but it doesnt .

I have a datsun 280z with this 350 sbc im running no hood and its only 68 degrees outside . Ive made sure the thermostat works and it does what its supposed to do . The entire setup is only 8 weeks old from jegs crate engine and all .

I cant run a clutch fan as there isnt enough room so i have a electric fan the pulls through the radiator at about 3,300 cfm with a shroud that covers the entire radiator . Hold a piece of paper in front of the radiator about 14 inches away and it will suck it into the radiator so it seems to pull air decent .

Nothing is in front of the radiator seperate trans cooler in a different place no place near the radiator . Cools fine in traffic sitting still but get going and it hits 200 then 210 and thats with a 190 degree stat . I tried a 160 degree stat and same thing 200-210.
