For sale is my 1971 Plymouth Duster. It is powered by a 340 and has a hewes 904 three speed transmission with a b&m shifter. Let me say ahead of time let me say I'm sorry because I do not know much more specifics other than that. I did not build or have this vehicle built. But I do know that this vehicle is far from stock. It has a agressive cam and has a decent amount of power I would say somwhere in the 400hp range. The transmission also feels as if it has a shift kit in it. If it has a stall then it would be small or a normal torque converter. The rear end gears are very streetable and not something that would be setup for a dragstrip. It does have power steering and manual breaks. All in all the car is a turn key driver. It doesn't overheat and handles good for what it is. Bring it to a show or drive it around town. It has been a fun car but time for so thing else for me. So good luck bidding and also I maytrade for the right item. Let me know what you have. I cannot ship and vehicle is sold as is. I also have the right to and Auction early. Contact me for more info 251-508-7318 thanks.
