727 Build for Mid-10s

For my build, 5 clutches will work just fine. Did I mention that's what was recommended to me by CRT? I think John knows a little about these transmissions.

Even if I bought 6 new thin frictions, the clearance would still be too tight and require adjusting, so the $20 I'm 'wasting' on a thinner pressure plate would still be required.

Keep in mind there is more than one way to thin the pressure plate.
The easy and cheap way is to throw it on a surface grinder and grind the entire plate. The other and more expensive way is to only thin the plate in the area wear the snap ring fits. A step grind which would require more setup time in the machine shop. Some builders prefer this step groove to better maintain the strength of the pressure plate so it cannot bow out.
