600 edelbrock secondary bog.

I still am suspicious of the initial info. I believe I read that you said the engine had 22in vacuum. That seems unusually high to me. At what idle rpm was that vacuum achieved?
750-800rpm but I could pull it in the garage to get some better numbers. Know my average idle vacuum went up slightly with this cam, which is odd. I was pulling 19hg before. If I would have known I would have went with something more lopey and aggressive.
I set my timing at wot, which put my initial at 17. I’ve tried everything from 34-45 at full mechanical advance, no pinging which I believe is due to the stock bottoms end and eddy heads, which drop your compression ratio by about 1 point due to heat dispersion, which drops me out of the ping threshold. I know I would benefit greatly from a better bottom end, but at the time I bought the heads, I didn’t know I’m new. everything I know at this point I learned by trying to figure out this carb, hence the vacuum speech, as I thought that was a possible culprit. Learned a lot, just apparently not what I need to know yet. Once I can figure this out, I believe I could make this run amazing on anything. But there’s something somewhere I’m missing.
I’ll get precise numbers for you this weekend when I get it back in the garage again.
