Assuming you have a stock 302, you should try about 10 degrees initial. Total advance is controlled by your distributor, so check that too at higher rpm. Like Tarman mentioned, about 35-36 degrees total is good. If you find your distributor is not allowing for a total advance in the mid 30's by 3500-4000rpm, you can try slightly bumping up your initial, You can also get some lighter weight advance springs in your distributor--again assmuming you have a standard style distributor. -dan

JP engine still stock with only change being carb'ed? Start with 10-12* initial and tune from there. Haveing or not having vacum advance will also effect what initial timing you end up with to get the amount of full total advance at the 3400+ rpms. Adjust timing for best performance usually around 32-34* max at around 3400 rpm and let initial fall where it will.
