Are you sure you lined up the timing gears correctlyy? Also using a new chain? If your sure then try the above post. Anybody ever use a ball of paper towell in the #1 hole to find TDC? spits it out every time.
We used to drop 4 jet sizes on a holly and i think a couple of numbers cooler on spark plugs. Never changed the timing and dont really remember about the plugs. This was for drag racing in denver.
