The Duster you guy's speak of was a good friend of mine's car till he had to go on vacation. Mike bought it and doubt he changed much but not really sure. It was a Yellow with black side stripe 340 auto. My friend had a ported set of heads and 11.1 pistons with if I remember right a Cam Dynamics 585 solid . The trans was a Manual VB done by Vitar and later Select. 8 3/4 T/A convertor and 5,13 gears.
In it's day pre Mikey it went 11.70's. My buddy used to stack carb. spacers to make a home brew tunnel ram under the Six Pack scoop.

It cleaned it's share of clocks when Ronnie owned it...

Mike bought it and primer'd it to protect the innocent.

I forgot how Mikey used to double park the Nova on 3rd ave. and then come out after quenching his thirst and repave the Avenue.
