also I got rid of the vacuum advance distributor and went with a mechanical one.. The racers said to lock the advance out... so there is no advance or movement of springs or weights, then set at 36 degrees.... the difference is night and day!!! very good tip I think!!
hi there, I had similar issues with timming. I asked guys at the Hemi shoot out drag race... seems like 9 out of 10 agree that 36 degrees total timming is the money. I did this on my 340 dart and it runs so much better.
