what is so hard building an h22.. boring and sleeving will take care of the cyclender walls and then with a build head and bottom end all i will have to really worrie about is the timing, detination is a verry bad thing.. other than that if i can push 20-30 psi threw that h22 ill have no prolbem reaching 500whp at least in theory.. mabey you could help me with identifying some prolbems i might run into instead of telling me its too hard. thanks
