Lesson for the day
In 1973 the Plymouth Roadrunner was available with the 8 and 3/4 with a 340 in front of it and also I had a 73 Roadrunner 400 big block car it came with the 9 and 1/4. I believe that was about the last year for the 8 3/4 in a car.
I also had a 73 Roadrunner with a 318 manual 3-speed on the floor that came with and 8 and 1/4.
I also had a 73 Roadrunner GTX that came with a 440 with the 9 and 1/4 behind it.
You may notice I like the 73 Roadrunner. Most of them are red but the 440 Roadrunner with the GTX package was blue.
The reason I want an eight and three-quarter to go under a Dodge truck is I'm not having a lot of luck with these 9 in the quarters. My 76 Plymouth trailduster has a 9 and a quarter under the back of it and I would just soon it had an eight and three-quarter.
