dave when i get out from behind the dyno i have a stock suspenion nova on drag radials that runs 8.30 street driven. if i what to go fast i have a chevelle that has 1900hp and runs 7.60@over 180 has been driven on a 400mile round trip. runs those time on a 10.5 slick. but we were talking about a 400-450hp engine all the things that you list aren't real word needs. slapper bars and sticky tires and the chassis stuff is done.. i just have a hard time giving advice and not telling them how to get every last hp.. i would like to have to much power then not enough. as for me i can never have to much power. i can just tune some out.
