About the timming chain being some teeth off
I always hear about people saying about someone's problem ( timming or whatever) that; Is your timming chain off a tooth?
The ? is when I rebuilt my engine ( past week) upon the terdown the timming marks were about, crank at 12 o-clock and the cam was 6-7 teeth off. The chain was a origanal one without the degree offsets. So what gives, am I missing somthing because the car ran great before, I rebuilt the engine to make it faster and it is and i put the new timming chain on correctly.
So the previous person who did the chain before could of just set the timming correctly for the improperly set timming chain? I still don't know how this could have been but it was :crazy: So please correct me on anything im just confused on the timming issue. :_dupe:

Re: About the timming chain being some teeth off (redfast)
You have to checked incorrect markings. It would probably run if it were off by one cam sprocket tooth, but no way with what you are describing.

Both the crank gear and the camshaft gear have DOTS stamped in them from the factory.
You align the 'DOTS' when installing the cam.
The way most do it is to bring the crank gear DOT to the 12 o'clock position and the camshaft gear DOT to the 6 o'clock position. This makes it easier to align the DOTS. But be warned, in that position, the #1 piston is NOT on the compression stroke, so DO NOT DROP IN THE DISTRIBUTOR AND POINT THE ROTOR AT THE #1 TERMINAL WITH THE CAMSHAFT GEAR DOT AT THE 6 O'CLOCK POSITION.
Yo will need to turn the crank one complete revolution, which will return the crank gear dot to 12 o'clock; BUT now the cramshaft gear dot will be at 12 o'clock too. Now you can drop in the distributor and point the rotor, . . .
So it's the positions of the DOTS that you want to pay attention to, not the teeth themselves.
Hope this explains it.
