Wellcome Fast 47. The 66 292 came with a roch. model B. The 292 carb. has a larger bore than the other models although they have usually been replaced with the smaller one. Although lean mixtures & incorrect ign. timing can cause overheating I doubt that is your problem. Make shure the radiator passages are clear & the radiator is large enough for the engine. Try another thermostat. I often find bad ones right out of the box. Blows your mind away trying to figure out what is wrong. smile


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
