Performance Results for the 1968 Cougar GT--E 427/390 HP

C-6 Automatic with 3.50 Gears and FR70 x 14" Tires.

In stock trim, 15.10 @ 93 MPH

Too heavy at #3616 lbs. for the Drag Strip.

Designed for a smooth road ride (road sports car type performance) with
the 'Special Competition Handling Package' and 123 lbs. of added
'Sound Deadener'.

And, 'Standard Exhaust Manifolds', not the 'special' 427 header-type
cast iron free-breathing units. A restrictive exhaust system, strangled
the exhaust flow.

The 'first' performance suggestion, install a set of 3.91 Traction-Lock
gears (at a minimum), which could get you to 14.75's @ 96 MPH.
