Deep stage . If you want to deep stage pull through the light's and back up till the state light come's on . But normally for low ET . Inch forwar till the Pre Stage come's on . Then just ease it forward till the light flickers and hold the brake and give it enough gas till the light stay's on with a sutomatic or inch it forward till light stay's on . With a automatic I would take off on the last yellow light before green . Very few street car's will red light . I used to count from the 2nd to last yelllow light in time trail's till I found the number I didn't red light on . I was cutting 0020 light's with a 88 Toyota Supra and put all the race car's on the trailer including the track's owner son with a 6 sec . 67 Camero a few time's. That was on Wed. night bracket race . I took the money . I came back on Sat. night for the big money . But this time they announced about I used to own the Black 71 Buick GS . Which friend's have ran NHRA Stock with since 78 . And now run's 10's in !/4 and low 6 I thnk at the 1`/8th mile track I was at. I got past the first round that night against the Camero again on a hole shot. But red lighted aganinst a 5 sec. rail by 0002. I paid everything done to the 71 Challenger I had . But did most all the work on the Buick GS including building the engine and turbo 400 . And told the machine shop just how I wanted everything . kenne Bell Buick really helped me with blueprint cam's and what to do. Love this new Challenger . Bring's back alot of good memories. Not sure if I told . I walked point with German Shepherd ( 95 lb. Black and silver ) named Noble to find mine,boobytrap's and enemy ambush . Wouldn't be here if not for him . Car's was one of the thing's that helped us keep our mind's looking forward to getting back to the World as we called the USA .
