I remember people saying the same thing back in '64 when the 273 LA series was introduced, '66 D-Dart first 13 second street car 1.2 H.P. per cubic inch Advertised @ 275 H.P. 501 solid lift cam, Doug Thorley headers, 10.5:1 compression, 4160 Holley w/ Edelbrock design manifold.
Building a motor to do what you want in the parameters of limitation always surprises the doubtful as well as the one with vision. Got to stay optimistic.
