I just ran my 10.5:1 512 out at milan Wednesday. Car didn’t hook with the 6 year old drag radials. I gotta think it’s 3450 with me in it. All steel 69 dart except for the hood and front bumper. First time out with this combo, I have some work to do. I did make some other better passes earlier in the evening but the timing system was down. I think it’s more about combo than anything.
