The slant or the 318

Well this is the problem, I have a Pretty fun Dart with a small block... I like the idea of being different. BUT the cost of being different is the question.
I dont do trailer queens.. The Duster looks great but needs rust repair repair in all the normal places. I changed up the exhaust its a "single" system but is split behind the transmission into "duals with 14 inch glass packs... Chrome tips and well fun to drive to a point.
