need help on cam choice

The only problem with calculating overlap is if your not doing at .050 it can be misleading depending on what the cam designer measured advertised at.The first lunati cam I suggested made 175 cranking psi in my 340 at zero elevation,the dynamic winds up close to 8.7.The 340 has trws with 6cc valve reliefs,.025 above deck,66cc heads with std. felpro head gaskets at .045 compressed to get 10.14 compression.
