Stock cam 360 idles bad, dies in gear, fixed!
If the cranking compression is on the low side (say 120-140) you need more intial timing.
a bigger cam with the stock compresion will always need more initial timing compared to the stock cam with less duration. I try to set my initial be how easy it is to start the engine. Just keep advancing the timing til it starts to get a bit harder to crank over, then back off the timing about about 5-7 degrees. Yes you most likely will need to recurve the dizzy so you dont go over your 34-36 (eg.) wide LSA's reduce the cranking compression because of the later closing intake valve.
