Using up that pile of 557 blocks that otherwise would be getting scrapped and capitalizing on them.
Personally there’s absolutely zero chance I’d invest 8 to 12k or whatever to build an engine off of a questionable foundation.
For those of you who are willing to roll the dice on a 400 - 500 hp 557 block build be my guest.

I agree, Bart. Considering the money spent on the 557 block to make it live, I would add a few more dollars and get a reliable block. Used 455 blocks are still around and a good source. A forum member is on his second 455 block and even that one has needed some work done to make it live. This one would last ages and and be rebuildable and easily sold:

Considering the $$$$ spent, the MR-1 iron block starts to look good. FWIW
