Hi I am doing a LT1 T56 swap in a third gen automatic, just wanted to know if there is any defference in these two pedals will either one work. I know I will require a master and slave for a LT1 T56. Thanks

 

Well, they look the same, but the geometry has to be slightly different. I have LT1 t56 pedals in my '86, and the pedal does not have as much travel as my brother's '98 LS1 t56 pedal. I believe the LS1 pedal would have too much throw, even though the clutch master is the same.

 

The pin near the pivot where the slave cylinder attaches are different sizes for the LS/LT cars. I belived the LS is bigger. The location may be slightly different but I don't think it is. If anything, the travel can be adjusted with a McLeod unit.

 

I mean the overall travel of just the pedal itself is different. From the floor, all the way up to the stop, the LS1 pedal has more travel.
