Re: Questions about using a timing light
I have read a lot about this on the team Chevelle forum and this seams to be the most popular way to set up the 350. I have done this to my 72 truck and it has never run this good. You have to make or you can buy a vacuum advance limiter. Attached is a picture of the one I made from a piece of aluminum. Crane sells one. You want to limit the vacuum advance to 8 to 10 degrees. Set your initial to 10 or 12. This gives you 20 or 22 at idle. A lot of the forums talk about this.
