Re: HELP with 390
As far as the white and grey smoke,....it's probably residual oil and water burning off that might have got into the cylinders. As far as your timing goes, pull #1 plug out put your finger in the hole and crank the engine untill the you reach the compression stroke. The dampner should be close to TDC. You'll see the timing marks rotate the engine to line it up at TDC, now reset your distributor rotor to piont to #1 on the cap, if you have a vacumm advance on the dist. make it point straight forward. You might have to pop the dist. out once or twice to make it fall into place nice and easy. hook everything up and start the motor.
