Match Race ~ 1968 Road Runner '383' vs. 1966 Mercury Cyclone GT '390'

1966 Mercury Cyclone GT '390'

Gear Ratio's
* 3.25
* 3.50
* 3.89
* 4.11

Most of the 1966 {390/335 HP} C-6 Automatics received >
3.25 Gears {Open-Rear}

And most of the 4-Speeds came through with the Wide-Ratio Transmission {2.78 ~ 1.93 ~ 1.36 ~ 1.00} along with the
'standard' 3.25 Gears.

The 390 was listed with;
* 335 HP @ 4800 RPM's
* 425 Ft/Lbs. of Torque @ 3200 RPM's

Draw back here, was that the 390 came thru with a #4150 Holley 600 CFM
{1 9/16" x 1 9/16" > Throttle-Plates}.

Most of the Ford Boys said that the Holley was too small for the throaty
runner-ports in the Intake Manifold and C60E-R Cylinder Heads.
