I plan on rebuilding a 454 big block. I've been all over ebay looking for a bare block. The cheapest block are Mercruiser 454. Reading a few post on the web about converting marine to street can happen if certain parts are changed. You can't believe everything you read on the internet. I was hoping I could trust someone who enjoys a lot of power in their hot rods to help me out. If I have a bare 454 Mercruiser block I'm ok to rebuild it and put it in a car?
