AS time passes theyll go up in value simply because there arent as many around any more alot end up in the scrap heap but so did some 340s 360s beleiveit or not 340s got thrashed and beat rebuilt and thrashed again etc. Id bet there will be a time when a 1971 318 2 barrel stock intake and carb will fetch a penny or two...
I don't know about that, either. That's like sayin flathead sixes are goin up in value simply because there aren't a lot left. Just not so. It's the same with 318s. Nobody really wants them. Same with slant sixes, too.
