Question Edelbrock Tunnel Port Heads??
I got my Hot Rod Magazine today (2/03) and I spied on page #92 and 93 an all aluminum 427 (Shelby block) taken out to 456 cubic inches.. Yea, nice.. It wore Aluminum Edelbrock Performer heads topped with a Tunnel Port Manifold.. Yea.. Nice.. 464 bhp through a C-6 (580 SAE est.)

The thing is.. When did Edelbrock start making Tunnel Port Heads?? These were flow tested at 325cfm / 235cfm and use 2.19 / 1.76 valves ( TP OEM were 2.25 / 195").. So they are not full TP units but they sure flow well.. The article goes on to tell how the guy is a 32 year Ford employee.. Hmmm..

Were these a special set of heads? How can this be done??

Regards,
