The loss of power was a combination of different things... As I stated in my original post, with my combination this only yielded 120-125psi compression, which is about 8.0:1-8.5:1, but this was certainly not the only reason... There were numerous factors which I won't get into, but this block was not an issue... This block will make some big power, just not as easily as the new more aggressive setup I want to go with...

Darton sleeving is roughly $1200 +shipping give or take a couple hundred depending where you go...
