I think I have posted it up on here, but I took a bone stock '72 440 that was originally in a New Yorker and I put it in my '83 pickup and pulled it out, and when I put it in our racecar I bet it had 80,000 miles on it at least, and put our Mopar intake on it with our flying toilet on alcohol and put it in our '67 Barracuda full blown racecar and it went 7.40's in the 1/8 mile, we took our 6.0 engine out and put this stock engine in it for my son to learn to drive it. Had to change the converter in the transmission, and had to go to a smaller pump and pills in the toilet. We won a little money with it in the 7.50 index at our local track.

And the timing chain had more slack than the one above, and it also had one cylinder leaking about 80%.
