When talking about poor fuel they do not mean fresh fuel necessarily. They are talking about octane rating. With a 10-1 motor you need AT LEAST 91 octane unless you have A LOT of cam. Fuel must match cylinder pressure. As mentioned earlier vortec heads like no more than and usually less than 34 deg TOTAL timing. This means 8 or less initial with most stock distributors which leads many people to overtime them. This motor appears to have been detonated or preignited to death which would be YOUR fault. sorry
