600HP 5.7 Hemi 75 Duster project

on a side note I am at $4000.00 for a running total on the project. and to have it street leagal again i need build an exhaust system, buy a rear axle that will handle the hemi (the 7.25 will not cut it lol) and get everything installed. so i would say im not doing too bad in the expense department. I figure i need to drop in another 2500.00-3000.00 to get it track ready. then im hopeing to see low 10's
