I would have to pull out a book to be sure, and then I wouldn't get to bed, as keep reading. But I digress. I do not think the 428 was made into the 1970's. Around 68 or 69 both the 429 and the 428 were offered for that year (maybe two). From that point on the only FE made was the 390 in the trucks. At least that is what I am remembering from a book. With that said I remember some trucks that had 360 in them in the 70's and I believe it was a FE also.

So I have conflicting memorys and I don't trust either. You may want to check on when the 428 was dropped. I do know that many 390 blocks were bored out to make a 428. Some end up with very thin walls and may not take any more bore. Be careful. It could be junk.
