Today, dollar for dollar, is the 318 faster than the 340 ???

all well and good,But I have five 318 engines sitting here that I would love to unload on someone.
But There is a waiting list should I decide to sell the 340 engines.
For sure 340's bring the money. When it comes to resale, no contest. The very reason for this thread. On a modest budget of per say 3k, is the 318 the smarter choice if a person doesn't have an engine ?? speaking of performance, of course
