[QUOTE="Travis Munday, post: 538975, member: 52914"] The compression ratio of the engine may be too high to safely run lower octane gas. The gas will predetonate and cause pinging and may cause further engine damage, so I woudln't really suggest dropping all the way to 87; 89 or 91 it might could take better. I've actaully got a question for you now, for my project car I'm using the brake system from a '71 LTD, master cylinder, booster, and complete front spindles with calipers and rotors. Well, I'm missing the passenger side rotor and backing plate, and I haven't been able to find a place online that sells them cheap, you know of a place? I haven't checked all the junkyards around me, but they are mostly later models so I'm not holding out hope. [/QUOTE]
