don't know what year you are talking about but when i started running 10.90. (this was the first year for the .5 tree for s/st) I was using a 1979 trans am. home made slapper bars. car flat out 10.60. i did not have any reaction issues with it. i did use a small front tire. there are a lot of tweeks you can do to make it react faster
