I have had a lot of cars over the years with 318s.
Some are better than others in stock form, but the best ones I have found are the '68-'69 318s.
Of course the compression was higher in those years, but they just plain worked.
They are dead nuts reliable and it doesn't matter the year, they go good for what they are.
I have never had or ridden in one that was hopped up from stock other than dual exhaust and a 4 barrel, but they have a lot of potential.
It's like a 340's little brother...
