You ever checked my homepage?
I've owned a 440 Dart. Getting to the plugs esp. the rear ones, with the 2-1/8" primary Hooker fenderwells was pure crap. Same as getting to some of the headerbolts. Even had the engine mounted higher than normal to get some clearance. I don't get warm and fuzzy thinking back about that claustrofobic enginebay.
I will never put a RB in a Dart again.
