no, i'm pretty sure there's no slippage, the tranny is the original '83 SROD 4-speed and could possibly have the stock clutch in it. what clutch kit would give light pedal effort with decent clamping force, good for about 350hp?
If it's not broke, you're not trying hard enough.

New T5 installed, driving my 'Stang again.
