Which clutch and PP?

I have a modest 367, that by it's trap-speed in the Eighth is putting out 430 hp.
I have the 1x23 Commando 3.09 low trans and 3.55 gears, that takes off with a starter gear of 10.97. and NO traction aides.
I also ran the CenterForce II setup, but found the disc way too aggressive, and like you it broke stuff behind it, everything broke from the trans input, to u-joints to the ring and pinion; with cheapazz BFG 295/50-15s And
It barked the tires hard-over going into third gear at 85mph.

Ok, so Here's what I did;
1) I swapped out the hardly used CFII disc, for a factory 340 disk; Halleluyah, what a difference.
2) but my engine kept tearing the hubs apart, pretty regularly; either spitting out springs, or fracturing the hubs, or tearing off the riveted linings,.. so
I got under the car, and loosened the PP off the flywheel, and one by one, installed large diameter small-holed washers between the PP and the flywheel, about 080, IIRC. Then torqued it all up. This provided enough slippage at low rpm , that I can almost just dump the clutch at idle and drive away. Yet by 3000 or so, she is all locked up by the flyweights. She doesn't bark the tires anymore on the 2-3 shift, but she still pulls off a 93 MPH Eighth.
And the 340 discs last at least one summer.
As I get older, they are lasting longer, I think the last one is like 5 years old, which is good, cuz I'm 71 now and gone are the days of dropping the trans in 17 minutes.
3) but I don't powershift. My left leg can still stab that pedal pretty quick, and I can be pretty far outside the preferred departure window, cuz Second and Third gears have been "slick-shifted". I can and regularly do, overpower the brass rings, and just slam it over, before the brass even knows what happened.

Now; far beitfrom me to tell you what you should do.
I'm just telling you what I did.
For street use, cheap and easy, is to reduce your clampload, little by little, until you can live with the current disc, or until it slips too much. I lucked out with 080 being just right.
BTW-1
I have never lost a 340 disc to overheat, and since 1999 when I first finished screwing this car together and driving it, I have never had the flywheel resurfaced; and IMO, that CFII PP has been very good to me.
BTW-2
My engine has seen three cams, and the cylinder pressure has varied from a high of 195 to a low of ~185..... just so you know. Oh and, with closed-chamber alloy heads she is happy to burn 87E10 full time.
BTW-3
driving around town at part throttle is now a pleasure, with no more neck-snapping shifts.
Generally, I might shift at 2800, cuz the engine is just coming up on the cam, and starting to sing. It drops into Second at 1750@20mph, then climbs softly to 2800@33, then to 2800@45, then to 2800@ 63, then into overdrive, for 65=2240.. It's a pleasant pull with the cam waffling from 2000 to 2800, a lovely melody out the dual 3" pipes. and a nice soft shift into each next gear.
But when I shift from Second at 7200, coming into Third at 5200;
hang the heck on, cuz that shift will want to rip the fillings out of your teeth and ram them down your throat, lol; Bloody hell ! ......... lol
