I have a 69 Mach 1 with a 390. It currently has the stock copper radiator in it. As far as the engine goes, it has aftermarket AC, an edelbrock aluminum intake manifold, headers and possibly a mild aftermarket cam, guessing from the sound of it. It tends to overheat. It also has a fan shroud. (Sorry if I'm every where, I remember things here and there). I've purchased a new fan and distributor which I have yet to install. It definitely needed a tune up and I decided to go with a unilite and some new sparkplugs. I'm assuming with those items alone it should help but I wanted to top it off with the best aluminum radiator for this car and where better to find out than this forum?
Nice car! U.S. Radiator make some good quality radiators. But, can be very expensive. Before spending money on a new radiator, when does it overheat, in town driving, idling, highway speed driving? What type of radiator is currently in the car, 2-row core, 3-row core, 4-row core? What type and size of fan is in the car? What temp thermostat is in the car? Many things can cause it to overheat other than a radiator including something simple like ignition timing not advanced far enough or air fuel mixture too lean.
