Thread: Question on rules for 10.5 class

Tweet

Well what I am looking at is not EZ Street,what I meant was True street.I am building my truck, should take about another two years and more money than my wife would like for me to spend on this project I have decided to go with smaller cubic inches just to be somewhat comfortable on the street.I still want to drive it to the local drive in.I am thinking some where around 700-800 horses.I am asking these questions also to see where I can best fit in,with my needs.Bracket racing is just plain BOARING.I don't want to build something that is not legal on the track. I am not planing on coming in and taking over the field,but don't want to take away something from the frame set up that will ruin my chances from going faster a year or two down the line. The fun in it for me is getting in and learning more about what it is going to take for me to go faster.
