For all 1968-1972 Corvettes, big blocks were equipped with front and rear sway bars (of varying sizes based upon standard suspension or F-41).
Small blocks (regardless of ZR-1, LT-1, F-41, etc.) received a front sway bar only.
As an added piece of information, original trailing arm (hard) brake lines were spiral armor covered on big blocks (to protect against chafing on the rear sway bar mount) while small block lines were not covered during this time period.

Well, I'll be... I've never had an LT-1, but for many years I was under the impression that the LT-1 and the "Z" cars got the rear sway bar. But, check into the AIM and....NOPE! Only the big blocks, as Rowdy Rat indicated.

Woops - I did not realize this was a 4 year-old discussion - sorry. I thought it was a recent post I clicked-on.....
I thought the Gymkhana suspension option added a larger front sway bar and a 7/16" rear sway bar to small blocks in the early C3s - but "I thought" is not a solid reference, of course (maybe someone who knows will chime-in here).
I'll be experimenting with a rear sway bar addition (with a 1-18" front sway bar upgrade) on a small block '69 coupe soon.
I'm gonna be very careful when dialing the set-up away from the designed-in understeer, but I want to be able to experience a 'loose', oversteer condition - then dial it back to a neutral, slight understeer under most conditions, but controlled 'loose' at the limit type of set-up. However, it's all theoretical for me at this point.......and fun !

I crew on Corvette vintage racers, and we've never used a rear bar on any of the small block cars we've raced.[/QUOTE]
Yikes - I probably don't need one then - but I'll still probably play around a bit - very carefully, of course.
Thanks for the heads-up gbvette62 - Would you mind sharing the size of front anti-sway bar that you guys use? (< 1", or > 1")? I'm assuming whatever's stock likely, being vintage and all....
Thanks again regardless !
