Here's a pic of my 71 Challenger I had 2 years ago. It had a 318 that turned a 12.9 run in the 1/4 with a 904 tranny.
No one could believe it was a 318 so It was used for a lot of streetracing( had to show them ) She was rough but she could run hard. She was my lil streetracer. A close friend of mine built the engine and tranny in the challenger so now Im having him build a 440 with me for the cuda.
