Earl,

if I am reading your post right, you have 9 degrees initial advance, a mechanical advance of 29 degrees giving you total advance of 38 BTDC. ? And it's all in at 2500 rpm, right? If so that is very interesting. Most advice & comments I'm hearing (Jim Inglese included) suggest starting out with as much initial advance as possible, not less than the factory spec for a HiPo (which is 12 initial, plus 28 from a stock HiPo dist. equalling 40 total). But if that is working well for you I certainly can't fault what is successful.

I'm starting at 18 degrees at idle and finishing at 39 at 2300 rpm, so far. I'm still in an experimental phase.

by the way, I got the Weber's & manifold from Jim I. as well. He is claiming no difference in performance with the screens I'm using. I do have some performance issues to be resolved, but they are not related to the Webers. I'll be doing a dyno session sometime soon to provide a definitive baseline for future comparisons and changes. I'll be sure to do a run with and without the screens..

The engine and car are new to me and I have no confidence that it was assembled correctly at a restoration about 10 years ago, or with correct HiPo pistons, cams, etc. It not been driven much since then, until I bought it in May. I drove it a 1000 miles home from Illinois over two days, and about another 1000 miles since.

Maybe it has a wrong cam, or maybe cam timing is off, I don't know at this point. But if doesn't want to rev happily like other K codes I've owned. It will eventually get to 6000 rpm, but it seems like it takes a year to get there vs my GT350 which could go from idle to 7000 very, very quickly. I know my old GT350 had a free-er flowing exhaust, but the difference seems more than that would account for.
