i have lots of time.the dart i have now came with a souped up 318.it had a way to big of cam for the stall converter that was in it. i ran a bunch of 14 flat 1/4 mile times and that with in a 3300 pound A-body through 3 inch exhaust. i think with a better converter it wouod of ran in the 13 in the 1/4. ok with that said how fast do you want to go and how much do you have to spend?? mopar65
