I am ready to start my 396 and have adjusted the valves twice now,I went by the book first,brought up no. 1,adjusted after loosening and getting rod to just stop moving,then I went 1 full turn.I did 1,2,5,7 intake and 1,3,4,8 exhuast.then I turned engine to 360 degrees to no.6 . then I adjusted lash for intake 3,4,6,8 and exhaust 2,5,6,7 . Is this right?I cranked the engine and its popping fire out the right header.It seemed a little tight to me so I backed them off 1/2 turn.I then tried what another mechanic told me,bring up no. 1 adjust ,rotate harmonic balancer 1/4 turn,adjust no. 8,rotate 1/4 turn,adjust no.4 and so on in firing order.This dont seem right to me because all the lobes on the cam are different positions.I'm still getting fire on right side and not the left.And I noticed that the fuel I was dumping in carb to prime,some had eventually run out the right header pipe and left a spot on the floor.What am I doing wrong?
