Why would anyone ever sell a 340? You take them to your Grave with you before you part with them. Screw the next guy. I better get a big Grave. I have 7 of them. :(
How about posting the vin numbers on your 7 blocks? Guys are trying to reunite engines and transmissions back to the original cars they came in. You could help reunite them and make a new friend along with some cash...
