You can hear the difference between stock internals and forged internals? You must be very observant.

Oh and yeah, he's not selling the whole car. I guess you aren't that observant.

Years ago I bought a coupe off of TR. The guy said it had a 347 in it. He even had a receipt. But the receipt just had "347 race motor" written on it. That doesn't mean that motor is in this car. I bought the car because for the price, it was still a good deal even if it was a stock motor (it didn't run). Many people (all of the smart ones) will do the same. They won't just trust the guy selling it to list all of the parts, they will want to see it themselves.

I buy and sell used parts all the time, but I won't buy internal engine parts from a swap meet because I can't easily verify crank journal diameter, stroke, bore size, etc. I know alot of people who feel the same way.
