My boys both have duster but they are sitting right now. My youngest runs a paint shop, has two side businesses, and is having a house built in Colorado right now. He has a 1974 duster and bought a 340 for it and I’m doing him a set of Speedmaster heads. My other son lost two jobs since the last election and is now a mechanic In Ohio. His car has been sitting three years but is actually come home this weekend to work on his 1970 duster. He bought a very nice wiring kit for it and almost has it finished. I have a nice shortblock on a stand and he had a very nice powerglide built for it. Hopefully it hits the track again this year.
