428scj blocks are very good blocks, the big question is what are you looking for. The scj came with 427 medium riser rods and was a very good engine i have a 1969 428scj for my latest cobra but i will still probably upgrade to a 427, more money but a better engine. price is always the biggest consideration a good buy on a 428 block in good condition would probably be between500-1000 dollars, remember that the great e-bay tends to drive the prices up, good luck.
