Well guys I've decided to sell my '66. It breaks my heart but it's just too much work for me at the moment. With the money I will make off of it and the money I have saved I hope to find a 69-70 Mach 1 in better condition. Anyway here's my question. On my 289 I have a Edelbrock Performer RPM intake and Edelbrock 600 CFM carb. I'm wondering if I should put the original parts back on...2v intake and carb. Will it make a difference to me selling the car for more or less? It isn't a hard job and could be completed in a day so I have no problem doing the swap. To keep it on there or put the original back on...that is the question. Thanks much guys I appreciate all the help.
