My neighbor that built my 289 called me today and said that he traded a Pontiac "Fiero" I think. For a 428 that came out of a mustang. He wasn't sure what year. I was thinking 68 was the year they put the 428 in a few stangs. I don't have the numbers yet, but was wondering if this is something that I should get. He traded him, thinking I might want this motor. The car he traded for it wasn't very nice and was wasting away.
