I have few questions regarding this distributor i got one recently from someone i knew with 2 hrs dyno time on it.

Not marks on the inside of the cap at all.

1st) It has been locked out. Is it better to run it locked out or to set it back up to advance with the springs?
What are the benefits and negatives?

2) Which stop bushing is best to use? Should i stick with the blue one which was installed?

Should i put the lighter springs in it?


Right now i have an HEI with 36 degrees total advance.

Meaning a rev the motor to about 3300 and set the timing to 36 degrees.

Is this a good way to set timing?

If you want to try it with an advance I would put the bushing that gives the least amount of advance and the lightest spring.

Yup. The biggest bushing will give you the least amount of advance and the light springs will bring it in the quickest.

I run a pro billet in my boat with the largest bushing and lightest springs. It's 14 + 18, all in by 3000rpm.

Locked out will give you better throttle response and be easier to bring up on the converter. Cons will be harder to start when hot but that can be fixed with a start retard. But if you want to go back to having mechanical advance its best to put the biggest bushing and have as much initial as possible.
