Looking for original 340

I had 4 69 Super Bee’s 440-6 4 gear cars in the early 80s. They were a hard sell back then. I pulled the 440-6 out and put 383s in and they all sold. 2 found their way back into their original cars. I is in a grain truck. 1 I traded for a bunch of 340 stuff. I still have 1 440-6 4gear set up from a 69 Charger R/T S/E. Kim
