just a question out the blue i was looking at a couple engines over on mustangsunlimited and i saw that they have a 5.0L with 345 hp for $ 3,749.64, and a 5.8L/351 with 240 hp that costs $ 2,397.64, and they also have a 5.0L 302 that put out 390 hp for $6,000....i would think that the 5.8 will cost the most ....why is the 5.8 the cheapest

 

I would imagine it has to do with the parts that were put into the motor.
