I am the LSR guy, but at this point, I'm still not sure whether a hydraulic or mechanical block would be the better choice. I think it would probably work either way for me. Some say that the mechanical setups can make more power for a given rpm, and may be able to spin more rpms without problems. However, if I wanted to do a "Franken" setup, then the hydro would be an easier setup.
Do you have any good blocks, TheMan?
