Re: Mopar To Release Lost A-Body 1/4 Mile Test Results
 

P-F Flyer,
I'll try to make it easier to understand.
1967 Barracuda (Fastback) 273/235HP Commando (weight #2952 lbs.)
4-Speed results
w/3,23 gears; 16.30 @ 85 mph
w/3.55 gears; 16.08 @ 87 mph

Automatic A-904 results
w/3.23 gears; 16.66 @ 83 mph
w/3.55 gears; 16.37 @ 84 mph

The results are from Plymouths own testing, with a race-proven driver at
the wheel. Results were kept quiet from the insurance companies.
Nothing special done to the cars, other than adjusted tire pressure
and mild tuning and track adjustments.

On their own special testing, to see if they could get the 273/235HP Commando into the 14.90's (sub 15-second range). I'll post that after I dig it up.

This is what we are referring to as "The bible"

Jeff,
I remember when my father got that soft cover enyclopedia book.
About 2" think. He got the book 'Bible" from the Parts Manager
at Meadowland Chrysler-Plymouth, Carmel, New York back in
1969. Not too many people had it, or knew about it.

Still remember the desription of the Super/Stock springs for an
A-body 2800 - 3000 lbs, with a 4-speed.
Also, the trick with 50/50 rear shocks, and reversing the front perch
mount for the driver side Super/Stock leaf spring.
Utilizing 6-cylinder torsion bars (.83 thickness) and Valiant V-100
6-cylinder front shocks.

I have the paperback version of the bible and I used it until it was in shreds. I still have it and it's held together with lots of tape.
It's the best book I ever read!

P-F Flyer,
Found it.
1967 Plymouth Barracuda (convertible), Formula "S"
383/280HP (A-727 Automatic)
Weight #3224 lbs.
The 67' 383 cars were only available with a 3.23 Sure-Grip Posi Rear.
The only way to get steeper gears was to order the optional
"Tow Package".
Not too many people knew about that one.
*Equipped with a 1 1/8" piston size for the rear shock, and self-leveling
spring adjusted (ie; Monroe-Matic) shocks.
*Some say an additional short leaf spring was added (a 7-leaf rear spring). Others say, a short 16" helper spring was added under the
back section of the 6-leaf rear spring.
* A "B & M" shift improver kit was installed in the valve body, and
heavier spring ? for the 2nd to 3rd up-shift.
* 4.10 gears
The convertible 383/280HP automatic was tested with this option.
14.67 @ 95 mph
