Funny storry,I got the truck home today to pull the motor when i can and talked to the original swapper that had the 440hp put in.He said a local mountain repair shop put it in and it was out of a 69 charger r/t.Funny thing was about a year ago when i had a 68 roadrunner project i bought a hemi 4 speed from the same repair shop and he said it came out of a 69 charger r/t.I know this is all true considering the Rural locatiion of the repair shop.I sold the hemi 4 speed a year ago when i did some trading with a guy and he wanted it for the RR.So i had the 4 speed from the charger and a year later i have the engine out of the same car,funny how things go around.
