My car has a Marine type 302 with a Holley 4Barrel. I dont think it is any more than standard. I checked the timing and it is about 10deg at 1000rpm, maxes out at 38deg about 4500rpm. I think the relatively high rpm is to do with the marine distributor. The previous owner said he used Lead Replacement Petrol, but that it would be ok on unleaded. I am running on unleaded, but do I need to adjust timing to suit? I have searched and found some threads, and 34 to 37 was the suggested range. Do I need to come lower down in to this range? Can anyone tell me any ball park relationships between ignition advance and fuel type for a standard 302? Also, would there be an advantage in changing the distributor advance weights / springs to a road characteristic?
