[QUOTE="9Trac , post: 538974, member: 55229"] I own a 2002 ST but this is about my 1971 Ford LTD convertible with a 400 cid and 2 bbl carb. For years I have been using 93 octane gas but with prices where they are I was wondering if it could tolerate 87 octane. I've never done anything to the valve seats. I guess I could go on and try it to see but I don't think I'd want to risk doing damage to the engine. Thanks for any help. By the way, the car is for sale, located in the Jacksonville FL area.
