I remember back in 1970 when Mark Coletti was piloting a Duster 340 in stock automatic and turning 12 flat ets for national records. I believe his father owned Coletti Chrysler - Plymouth in Hillsboro Oregon. A guy named Twig Zieglar was his engine builder. I got my Duster 340 to run mid to high thirteens with a 3 speed and 4.30 gears. It also had an Edelbrock LD340, Holley 780, headers and Riddler cam from Coletti Chrysler-Plymouth. They never revealed the specs on the cam, but I suspect it was the cam from the 68 four speed 340.
When I was tearing the dash apart I found a time slip with an E.T. of 13.59 at 104.77 mph. Well its thirty four years since I had the car on the track. A complete rotisserie restoration on the car was finished this spring. It now has a Kiesler 5 speed with 3.55 gears, complete engine rebuild with Crane 454 lift street and strip cam, TTI headers and H pipe, Edelbrock Performer RPM and 600cfm carb. I'd like to take it to Wisconsin International Raceway sometime to see how she'll do. It seems faster out of the hole now than it was back in the day.
