69 formula S 340 worth?

Question again?Do you mean he bought a Challenger with a 340 in it.Stock running tired 340 around here $1000.00-$1500.00.Complete engine out of car that needs rebuilt $500.00-$1000.00. Jim

yeah, he bought a challenger that was origioally a 318 car that someoone put a 340, out of a69 formula s cuda, into. would a 69 340 be worth more if its for a formula S car?
