damn now i remember why my ol man always threw away HEI kits and we ordered MSD Billets..... which i might have at the house a brand new MSD billet and I have a 6a box here just need to get a coil

If your base timing is to high like at 15*btdc and your mechanical is giving 25 because its worn then the combination will give you 40* which while is not bad it's still a tad high esp if your octane is low. Worn hei distributors give a lot of advance sometimes more than 25* in bad cases

Try and get 38* by 3500 rpm at least. 10-12* initial is about what stock-even cammed engines like
