I've said this many times regarding 318s "If there was some easy affordable recipe to make them go fast we would have known in the 80s...the recipe is and was to get a 340 or 360..."
serious question: when was the last time you bought a 340 or 360?
yeah 340's pop up here from time to time but they're not growing on the trees next to the 8.75 bushes like they were back in the 80's broham, and they have the price tag to match.
and 360's ain't gettin' no cheaper. everybody that has one thinks it's gold now.
