----My 70 LT1 that I bought new ran 12.90's shortly after I bought it with headers, and borrowed to tall slicks, with a 3.70 gear. Literally no tuning what so ever. The slicks were so tall I ran thru the traps in third! That's fact and at the time surprised the hell out of me. Still does!.....Bill S
