My old third removed cuz had a 426 dual over head cammed quasi-moto inverse solid roller with 1.8 rockers and a 5 speed manual rock crusher with dual plated clutch run 9’s in his Duster all factory stock except the uncorked pipes off of the factory 2 inch header tube. He did use slicks though. It’s amazing to hat the factory sold sub 2,000 lbs cars with a warranty back in the day. Radio was also pretty good. Drive that back and forth a 100 miles one way to the track. Those 5.13 gears would whine a bit on 75 on the interstate but it was bearable.
What made it easy was driving king the beers and a little Mary Jane on the way to keep it interesting ya know!
