I took my 66 mustang out to sonoma raceway tonight for the first time. I was expecting 17's but got a best of 15.7. I have a 302 (brand new long block) freshly rebuilt c4 with no upgrades, and have no idea what gears I have. Once I get some bigger tires Im hoping to be able to foot break it and get a little bit better ET. What are you guys running and on what setup?
