67 Suspension

[Dave Henshaw]

How do small block suspensions differ from big block suspensions? I have been told that small block cars came equipped with a smaller diameter front sway bar, no rear sway bar and a 9 leaf spring. Big blocks had a beefier coil spring rate, 7/8 diameter front sway bar, nine leaf spring and a rear sway bar. F41 cars were equipped with a 15/16 front sway bar, a 7 leaf spring and a rear sway bar. Is this correct? Was there only one size (diameter) rear sway bar used in 67 for Big Block cars or did the f41 option use a different rear sway bar. Just trying to learn how they were originally equipped from the factory. Thanks for your help, Dave

Dave, You've got it correct. All this info plus LOTS more is in the NCRS Judging manual. You may want to purchase one for reference at the site above.
Only 1 size rear sway bar for all appropriate applications.

You have it almost correct. Here's the corretions/additions:

1) the rear sway bar was NOT part of any suspension option. It was part of the big block option. With a big block, regardless of suspension, there was installed a 9/16" rear sway bar installed in PRODUCTION. With small blocks, regardless of suspension, there was NO rear sway bar installed in PRODUCTION;

2) In addition to the 15/16" front sway bar and 7 leaf rear spring. F-41-equipped cars received HD front springs with wire diameter significantly greater than any other springs;

3) Big block cars with standard suspension used different front springs depending on whether, or not, they were equipped with C-60.

Addendum

Also, although it was not mentioned in your original post, there weree a few other component differences with respect to the suspensions for 1967 (and, other years):

1) all cars regardless of engine received the same shock absorbers EXCEPT those equipped with F-41. F-41 shocks were different. They used a larger piston (and, consequently, tube diameter). The rear shocks used no debris guard for the shock rod and the rod was exposed;

2) the shock mount shafts were different for standard suspension and F-41-equipped cars. I'll be posting some detailed information on this aspect in the near future. Stay tuned!
