1970 deuce

[Salvatore]

Wouldn't the Deuce manifolds be the same as the SS 350/300 novas for 1970? I also can't believe that there were much if any restriction differences from the 70 Z/28 manifolds and the LT-1 corvette manifolds. Same size but a little different shape to fit the frame? Dollars to donuts GM did not design a better flowing exhaust manifold for the corvette just to say it has 10 more hp. They gave it 10 horsepower to put it tops in its class. Its called advertising.
