I'm not so sure that Force let him go, he just brought in younger blood to help do his job as crew chief, Coil is about my age (early 70's) in fact i used to race against him in the mid 60's when he was a part of the Chgo. land Dodge boys (Forconis,Memic, & Coil) I was running A&B gas supercharged, and AM/Sports and they were running Super Stock, but were sometime thrown together due to not enough cars to run that fast. I think that Austin just felt left out of the circle and decided it was time to move on. You have to look at a 25 yr rain with Force and the most successiful rain in NHRA hstory. He has said he was intrested in Nastliga funny cars and that is where he really got his start running 50% nitro and no electronics. I think he'll do good and enjoy doing that kind of tuning.
