McLeod Clutch and Pressure Plate
Return to the prior page My GT 350
When you take out an engine, that is a great time to check the clutch and pressure plate. In my case, I had put a stock unit in it when last rebuilt in 1983. Not a lot of miles on it, but I did a parade for John Chun. I don’t do parades but this was a request from John. We did ok following a marching band until I got to this hill. If I’d let the clutch fully out I would have run over the band. Dilemma for sure. So I ended up giving it gas to go up the hill with the clutch partially engaged. Smoked it badly. The guy in the Mustang behind me said he thought my car was on fire. Oops. When we pulled it out sure enough, my existing clutch and pressure plate were burned. I was bumping up the horsepower so might as well bump up the clutch. The labor was going to be paid regardless so I went on a search to find a new clutch and pressure plate.
There are LOTS of new clutches and pressure plates available for this engine. Dan, the engine builder, told me to get a diaphragm pressure plate. OK, what is a diaphragm pressure plate? Turns out in 1968 the pressure plate used was a three finger unit. Often referred to as a Long or Borg & Beck style pressure plate.
The newer Mustang clutches are all diaphragm, meaning many fingers. The next question is whether to go with a stock level part or upgrade. I was hoping to add 100 horsepower. Maybe it was time to go with a heavier setup.
Racing clutches are heavier duty to handle more horsepower cars. But a racing clutch takes a lot more effort to engage a mechanical clutch and hold it in. My mechanic suggested staying stock, saying I wouldn’t like a heavier clutch. My brother told me about driving across town in a car that had a racing clutch and that he wasn’t sure he was going to be able to finish the drive using this real stiff clutch. I didn’t want that so I decided to go with a clutch that was one step above stock.
The next question is to choose a vendor. Too many choices. After much research I decided to go with the McLeod diaphragm clutch and pressure plate.
That decision turned out to be an excellent choice. I love this clutch. McLeod make it easy to see what levels their clutch and pressure plates are targeted at.
My Mustang had a 10.5″ clutch disc. The McLeod diaphragm clutch for my application was a 10″ clutch disc. Dan, my engine builder, said the 10″ would be fine especially since this setup was much better than a stock unit.
Dan wanted me to get him the McLeod clutch and pressure plate so that he could balance the engine with them on it.

My Thoughts on this Clutch and Pressure Plate
I was able to put about 300 miles on my Shelby before putting it away for the winter. Really, I’m still breaking this clutch in. But I like this clutch and pressure plate. It is a bit more stiff than what I had in it but not too much. it does a great job of grabbing the torque from this engine. It engages and gives you the confidence it will transfer the power to the rear end. Racing clutch with my racing engine.
Side Note: I got the break in mileage done on the McLeod setup before I parked my car for the winter. I’m pretty happy with the choices we made. This clutch and PP are pretty awesome. I sure appreciate how easy McLeod made it to choose the correct setup. The other vendors do not approach it like McLeod does.
