Do slant six swaps make you feel guilty?

bought a 80 D150 bout a year ago...perfect red express clone material,..had a knocking /6 in it,..500 bucks...stuck bearings and pump in it and cleaned crank up but was still knocking,..my buddys keep pointing to my running 86 318/904 setting in corner but i said no,..found a running /6 on craiglist for couple hundred bucks,..swapping pans discovered the knock was wrist pin coming outta a piston...318 going in a 73 duster im collecting parts for and im on fence bout my 75 duster its a /6 but i still got the 318 thats in the 73....i enjoy the drivability and gas millage of the /6 but like the high rpm small block to...guess im all twisted...dwb
