Joew. boat is a 10x better deal......all weak links of the 525 have been addressed if Eddie went through them.

Thank you sir. To be clear, Young Performance built one engine. New block, crank, etc. It is built to take much more power (700+) then a 525 in other words, it is ready for a whipple:)
The other engine was a complete long block rebuild I purchased from pier 57.
I have the build sheet on both.
The third engine (spare) is mercury sealed, and has no issues.
