Default Tunnel Port
Bill, thanks so much for the info! What type of horsepower increases can one expect if they go with a tunnel port as opposed to using regular heads and a single plane manifold? Any suggestions on tunnel port heads? Are tunnel ports a popular configuration on today's 427s? Thanks again!
