Ok Im running 440 at 10.1cr, eddy heads, single plane intake, PCV hooked, choke hooked, and a purple shaft ...661 cam. (250 something @50, .557 lift), fuel pressure reg set at 5.5psi. Initial timing set at 20* total limited at 38*.

Ok with the transition slots square I have a ridiculously low idle of about 500 and usually less, which it will do but not well when running around town. Its much happier when it idles at 750 to 800 rpm. The mixture screws are set at between 1.5 to 1.25 out. after that I dont notice any other gains.

To get the idle speed I would like the transition slots are severely over exposed.

I dont want anymore initial, and I have tried it up to 30* but really was unhappy with the overall results.

I have spent the last 2hrs doing google searches trying to figure out the best method to get about 300 more rpm at idle am I at the point of drilling?

Just for the record, no vacuum leaks and NO im not switching off my tq.

I'm not trying to be difficult, it comes naturally....
