Basically the Lancer was a 104 development with a turbofan
afterburning engine, highwing, low elevator. There is a picture of the
mockup o page 124 in Motorbooks International Warbird History
"Lockheed F104 Starfighter", ISBN 0-87938-608-8. In the book it is
called 'CL-1200', the designation we knew it by, and is said to have
been engined by the J79-19. We understood (as best I remember from
1969) from our tech rep the J79 engined version was the CL985; the
production version (CL1200) was to have a turbofan afterburning engine
of around 25,000 pounds of thrust in AB. Performance would have been
superlative judging from my hours in the F104A with the J79-19 engine.
Endurance and range, even without additional fuel, would have been
rather greater than the 104A/Dash 19 because of the higher sfc with a
turbofan. Since the Dash19 104A would cruise at 1.05 in military
power, I am of the opinion the CL1200 would be capable of somewhere
around 1.2 or better in miitary with military thrust close to the Dash
19's AB range. It is true that Kelly didn't suffer foools gladly. And
he never held back on calling a spade a spade. So the USAF high brass
got tired of being told they didn't know anything about airplanes in
general and fighters in specific and did blackball him. See Ben Rich's
excellent book "Skunk Works".
