SS Springs and Slide a links

Slide a links WORK , especially with stick shift combination
For what I know : S.S. springs fight the Cal Tracs , not necessarily the Slides. What I have seen dropping the clutch on a 425-450 horsepower 327 ,in a 4:56 geared 66 Nova . ( it was,gutted, and caged. Went 11:7 ,@ 116....
Using Slides...closed exhaust, street radials ...not dot legal stuff



That's exactly where I put my combination to be. 11.7ish.
