Six Pack Idle

I had an issue with my idle on my six pack . It was all over the place. My Mopar performance dist. had 2 light advance springs in so I replaced one with a heavier one and now it returns to whatever I have it set at and that is great.My question is at 1000Rpm's at idle when I put it in gear it drops 300 rpm's . I don't ever remember that it should drop that much.The engine has a 484 lift cam 30 over 915 heads and a Hemi street stall converter.

Thats Moparts

whats your timing at? vacuum advance hooked up? it could be on vacuum advance at idle that disappears whenyou put it in gear. disconnect thevacuum advance and plug it at the carb. set the timing to 15-20 degrees initial and see what it does

I have the vacumn hooked up and the timing at 10 degree's Just took it for a ride and it is really lazy in low gear but much better in 2nd and drive.Stopped and put the timing up a little and it was better didn't ping but not great.

Thanks
