The car will definitely feel like it broke the first pass. Haha. When we ran there a lot and went fast. We changed gear 6.14s to 6.50s put in a looser converter, also ran a shorter tire then we normally did, changed timing a couple degrees, we ran a q-jet but made a multi step adjustment to the rods and when we really wanted to go fast also changed camshafts from what we ran normally. As Tom said if you are the only one in the class and can run under. Change the jetting and call it good and drive it
