Mild 360 stalls when I put it in gear.

If your vacuum is dropping alot at in gear idle it's probably trying to pull more fuel and that's killing it. The fact that new plugs helped would seem to support that theory. A true vacuum reading in and out of gear would help the diagnosis, and give us a measure of how much cam you really have. If your considering changing carbs. i'm curious what intake you are running. Do you know your compression ratio? I'm biased on the subject, and not sure how much cam you have, but big, meaning 240 deg. @ .050 or more are much more managable with a Holley carb, jmo.

Hi Bob, i think if you have you timing close, 14-18 initial your good for now. I still believe the lower vacuum in gear is causing issues in the idle circuit. I found this thread and maybe this could help.

This wont make me popular, but some think it's a badge of honor to have a large cam engine idle at 700-800 rpm. I know people don't want the car to die in gear, and i agree. But whenever i ran a cam with more then 230 duration @ .050 and lobe centers closer then 112* i always neutraled the car anytime i was stopped more then about 5 sec. anyway. Guess i'm just old school, i always drove my fun cars like race cars:D.
