Is the proceedure the same as when just the cam is removed & replaced? I have a new timing chain set and new cam. Do I just align the dots on the crank sprocket and cam wheel. Would this also correspond with #1 at TDC?
This would be the same as installing the cam straight up?

If not how do I proceed.

Thanks

If you align dot to dot and the crank gear has a single key way then the cam is intalled straight up.

If you have a gear set like cloyes 9-3110 you have a crank gear with three key ways which will let you intall the cam 4° advanced, straight up, or 4° retarded.

Aligning dot to dot is for cam timing alignment and does not corresond to TDC

Dot to dot (crank at 12:00 and cam at 6:00) is TDC #1 cylinder on EXHAUST stroke. That means #6 is TDC firing when you put the distributor in.

Thanks. Yes only one key way, so I'm on the right track. :cheers: :hurray:

Some cams have an advance ground into them. For a cam to be installed "straight up" its position after instalation, including any advance or retard from extra crank keyways would be 0 advance and 0 retard. Thats true straight up. this is why its nessisary to degree a cam when installing. Degreeing will take into account all factors including cam grind and keyway location and any other machining differences of all parts invloved. Reading the cam card supplied with a new cam will indicate if there is an advance already ground into the cam.
