I went with the Mcload hyd. T/o bearing because ofthe limited space I have since I have a T56 and while I love the pedal feel it just got put back together (150 miles) since the pedal stop allowed for too much travel. Also the fluid is not Hyd. fluid but is actually brake fluid...Much easier on the friction plate.
I hope that is will finally allow me to drive the car with the new Dart heads!
First off, sprint cars (world of outlaws) don't have clutches. They don't even have starters.
Second, the McCloud TO bearing has some "issues". My customer did a six speed swap in his 351c powered cleveland, and used one. He's driven the car less than 3000 miles and had it out no less than five times becasue it leaks.
If you use a hydro style TO bearing, I'd highly suggest getting something OE and late model like off a '06 or newer Mustang.
No. It offends us crackers.
Might I extend my heartfelt apologies to all the honky, white men can't jump, patty headed, red neck crackers out there.

Yeah a Clutch MC is $45 and the Slave Cylinder is $15.... Doesn't get much cheaper than that.
PLUS, they are stocked parts at many autoparts stores so if it needs to be replaced you don't have to source it from the internet.

I used CNC components to make my hydraulic clutch setup. Ran the line myself. Easy, cheap and very reliable.
An update on my customer who kept puking his McClod hydualic TO.
He took it apart again and swapped the engine into another car. The scattershield and the trans adaptor apparently had an interference problem that would intermittantly let the TO hang up on the adaptor and thus bind it up. He got lucky when he took it apart this time it was still jammed in the "bound" postion so he could see it. Once the unit got bound up it didn't have any choice but to fail.
About 20 seconds with the diegrinder would have fixed it, but my customer is installing a '03 Cobra engine he scored. He was relieved that he figured out what the problem was and let me know so I'm letting you guys know.
If you use a trans adaptor and a scattersheld, check your clearences real carefully.
