This morning I started my cam swap.I'm using a TF stage 1.Should I advance it 4 deg to bring the powerband down? I'm using performer heads,cobra intake,stock bottom end.Also do they make offset keys for the crank? Tried to buy some from Summit and the kid said they only came in 4 degrees.Is that true? I thought they came in 1 deg incriments.Why I'm asking is I'm off by 1 1/2 deg.I started tearing it apart at 7:00 am and got fed up around 6:00 pm.I was getting pi**ed off and figured I better walk away till tomorrow.I'm gonna start over just to make sure I didn't miss anything.
