Where is the timing to be set at for a 1962 Chevy 283 engine?

each engine is different but give it to a mechanic and let him set it to somewhere around 32 - 34deg total timing. This will take the vacuum of the engine into play as well. If you don't want to spend the money take the vacuum off the carb and set to 4-6 deg on your timing cover. This will be pretty close to the same setting. If you have difficulty starting turn counter clockwise just a hair and you should be ok.
