I don't see the point in answering 30% of a question on 20 different threads covering the same subject. We know the 500557 block is weak but what about the rest of the castings.
Brian and Ken, it would be a great help if you would post the block numbers that you would only use for race applications (high HP builds) and the castings that should only be used for moderate power levels. Thanks for posting the 500557's limitations and hope you will be willing to share the rest of the goodies.  |
I'm not a casting numbers geek. I only looked for what Ken advised me to look for when I found my block, and part of that was the extra ribs cast into the wide ribs that run in the lifter valley from the deck to the lifter bores. You want all of these "good" blocks to get scraped up by vendors and put out for sale for $1000 when they're only worth $400-$500, then we'll go ahead and post all of the pertinent info.
