318 value

well if its any consolation and if you can use this info and adjust prices to "todays money" I bought a 318 and a 904 for $40 dollars about 15 years ago, then turned around and sold it for $ 100 about 8 years ago...I sold it to my wifes uncle who wanted it for a 39 Plymouth so I figured why not he's family and Its scrap prices anyway...it sat ion my garage 7 years so I wasn't doing anything with it but I have two 340s and a 318 to play with so why hoard it?
