318 or 318 ?? which one

i have two perfectly good running 318s one is a 1969 and the other is a 1974. i got the 69 out of a 70 pickup but then found the 74 complete factory v-8 car. I planned on just pulling the complete setup out of the 74 and dropping it in my 70 swinger but then somebody said the 69 motor would be better


thanks
