Gulf super and 1 can of octane booster and open headers to get it running. What a sweet sound to hear it run. I used a 750 Holley to break it in, now I have to install the inner valve springs after a few hours of running. Then I'll put the 780 on and give it a good run. I had to prime the racing fuel pump and tighten all the leaks because of the high pressure. Next to have My Son make the stainless steel exhaust. He used to work for Pypes. NICK L72
