I have a FRPP King Cobra and I run a 125 shot with no problems. I had a Valeo "King Cobra" and burned it up in about 4000 miles, or the first time I hit the spray with drag radials at the track. Valeo makes the King Cobra for FRPP, but for whatever reason, the two feel totally different, and I have had no problems. The price difference was $10 at Fordspeed. You may want to think about a clutch quadrant/cable/firewall adjuster set, if you don't have one already. Also, RESURFACE the flywheel and get new throwout bearing. One last thing, are you sure it is your clutch or could it be you T-5? You sound like it may only slip in 3rd gear. Hope this helps, and hope it isn't the T-5.
