It's so simple, even I could do it!
I have been trying to set the timing on my son's 68 283 and my 63 350 for days. Had them running but they were far from right. I finally read "Timing 101" in the FAQ section (4 times) after I couldn't find any rock hard answers. I realized that both trucks vacuum advance were hooked up to ported vacuum at carb. I searched engine bay pics on our site and it seems most of us have the vacuum advance hooked up to ported vacuum (passengers side on my edelbrocks). So I switched both trucks to full manifold vacuum and set timing according to "Timing 101" and WOW!!! What a difference. I had way too much initial timing before. Just wanted to pass this along, maybe it will help someone else. Read "Timing 101", great eye opener. Happy New Year!!!

The knowledge here is overwhelming. We all run into what we think should be a simple task, that we make..well big....and the folks here help get us back on line.

Re: It's so simple, even I could do it!
I had the same experience. I started out using the timed vacuum port and 10 degrees advance. It idles way better on full vacuum and 8 BTDC.
