Plug size and timing
I know this is an old thread but I’m in sort of the same situation. I have a 64 cutlass with a 330
4 barrel and the 442 cam. The car was a 290 HP engine so I’m guessing that it is the same as a 442 engine now with the 442 cam. It has
aftermarket harmonic balancer that was supposed to be for a 64 or 65, the problem is the timing marks are on the left side. So timing it has been a challenge to say the least.
I’VE been using a vacuum gauge to try and set it.car has Thornton exhaust manifolds with true duals and a pertronix ignition. The plugs are R45S. My problem is where to set the timing and should I go with R43S plugs? The carb is a stock one from an automatic and the car is now a 4 speed. Also should the plug gap be 35?
thanks Brad
