I get it makes sense to want that extra 50lbs-ft or so across the rpm range especially in a street car, for basically free but some don't for whatever reason, not like you can't build a decent 318 and if that's what they want and know the pros and cons, I don't why people insist on trying to change their mind. A 318 has probably a 300% potential over a /6 and what a 90% of a 340/360 there could be far worse things to spend your money on.
