I need ya'lls opinion. I am seriously thinking about either a 5.7 or 6.1 Hemi swap for my 66 500. My car is considered a survivor car and is stock even down to the original paint. I love the idea of having the dependability and power gain of the new technology but do I dare do this to an all original car? If I do decide to do this, I plan on keeping the 318 poly and maybe build it and throw it back in someday. Please, tell me what you all think!
