[FFR428]

If these are still std bore with low hours closed cooling run in fresh water for a decent price grab em. The marine blocks are a very heavy duty block. Some say better than some street blocks. Keep in mind though the wear and tear on boat engine is like driving a car uphill all the time! These sound nice though and i've seen some really rough marine engines that people want top dollar for. They figure its a 427 and they can get sideoiler price for a crappy overbored corroded marine block! No way. G.
