Street performance tips, 225 slant 6

Aussiespeed!! So Sweeet. I think most of the CLIFFORD stuff is poorly made. My buddy went through 3 headers and gave up (header gasket to head leaks it had to be ground flat and used washers). The customer service sucks and the support?? well only 2 manifolds, 1 header, 3 cam choices?? I'm goina run an Aussiespeed 4, Hookers, and see about the carb procharger setup. ** MOPAR ACTION OCT 2008 PG #76** I love the /6 motor. I have a 1965 Dart GT with a 225.
