a mild 318 will not kill a stock rear but you will burn one tire off because of the diff. Right now i have located a mopar 383 and am considering putting it in my 86 d50 or my 84 dodge diplomat. here is a secret guys, cut the motor mounts off flip them and mount them lower and you can fit a 440 without hood mods. I have a small writeup of a guy that did this. i talked to him and its not as hard if you know what to look for but a 440 will kill the stock rear i am sure so he went with a differant rear also so he could get a LSD.
