Gentlemen, (and ladies...) I need some serious help with a 70 Roadrunner that I am trying to piece back together. The k-frame was damaged beyond repair so I decided to go aftermarket. Does anyone know what the crankshaft centerline should be compared to the frame or any other reference point? I am planning to use an engine plate on the front of the engine but I need to know where and how to locate the engine back to the stock location. Any help would be appreciated.
