When I was an engineer at ford, there were 3 guys working at our site that bought Cobra's and they got the emplovee discount price. One guy worked a deal with holman and moody and traded his high riser and cash for a 427 TP with 2 fours. 780 HP at 6000 in 67. The tunnel port wouldn't come out of the corners at Riverside as well as the high riser, H & M did better times with the HR on the road race coarse. A tunnel port with tunned headers would sound fantastic at bonneville. A couple oy years ago some guys had a nascar ford there> Build your TP motor and tell us when you will be at B'ville
