I thought d2 was to be a junk yard motor.i think sun prairie ruined the junk yard motor concept.a car I helped put together was a real junk yard motor ,300 bucks,and won a feature at grundy last year.the dad and daughter that drove worked on the car every night until it went around the track.and it was a 300 buck motor.factory crank rods block head.that is what I thought d2 was about.
