65 dart small block

I have a 1964 Dart Gt with a 340,fenderwell headers[installed in the 1970's direct connection]I ended up using the earlier truck motor mount on the driver's side!!!My car also has a 4speed and a8 3/4 rear with 391'sand has no problems w/vibration or the dredded problem of broken rubbers[HA HA]anyway I've pulled many holeshots that has scarred alot of concrete around my hometown! I hope I helped and if you'd like pictures of 340 manifolds I'll try to get a picture from a friend that may have them installed on his 64 valient 318!!!
