I just put in my 412 stroker into my duster and before when it was still a 360, I had a fan shroud, 2 row copper cored rad, engine driven fan, no clutch, and auxiliary electric fan, car ran fine 180-190, unless I got stuck in traffic then it would go up to 200-210 max cause then the electric fan would kick in and keep it at 200-210, so when I decided to have that same engine rebuilt into the stroker it is now I bought a brand new Jegs crossflow 2 row 1 inch tubes aluminum radiator, Flowcooler water pump, 180 mr. gasket thermostat, and electric fan 2500cfm (puller) no engine driven fan, and no shroud, I am running a external tranny cooler and also tranny oil through the rad, So now the 412 takes a little time but climbs to 220 -230 and will not come down, no matter how fast I drive, I am leaning to thinking I will have to get some kind of shroud and maybe have to go back to an engine fan, (didnt really want too) turn the elecrtic into a pusher in front, Jegs has aluminium shrouds, that you attache an electric fan to but Ii don't think I will have enough room for that, timing is set correct, 12 degrees initial and 35 max advance, the machine shop that built my motor set it (in car and drove it) so I am pretty confident they have it set correctly, what do you all think??
