Alright guys, ive got a 400 stroked to a 461, with sd performance "old faithful" cam and 4x heads. My question is what kind of clutch should i be looking at? Will a "stock" cluch hold this setup or should i be looking at an upgrade? If i need to be looking at aftermarket, what would you guys recommend?

People have a Love/Hate relationship with the Centerforce Dual Friction. 8-9 of the folks who actually have them will say they love them while 1-2 people will say they are absolute junk (hmmm ...) I am running them in both of my TAs: one with a mildly built 455 with box-stock E-Heads and the other with a 461 stroker with ported E-Heads and more cam. Both clutches bedded easily, engage smoothly with zero chatter, and have (relatively) easy pedal effort (mechanical, not hydraulic). Most important, both hold without issue. I’m guessing the 455 makes around 525-540 tq and the stroker should be around 550 tq. (I ‘think’ the CF DF is rated at 600 or more?). Mine have been in service for several thousand miles in both cars with zero issues.

As far as any anecdotal reports about holding capacity or lack thereof, this is the ‘street’ section. For a strong ‘street’ driven car that may make a few passes at the local track, I don’t think you can go wrong with the CF DF. For those running slicks and making repeated track passes, something else may be in order.

I have a RAM HDX behind my 505, it's basically a heavy duty diaphragm pressure plate with an organic disc. It's held up fine under street use.

Personally, I think clutches last longer behind a big engine on the street than behind a smaller engine. There's no reason to rev the engine up to 5000 RPM and drop the clutch to do a burnout, you can just rev the the engine up a smidge and ease into the throttle as you let the clutch out and you still go sideways. Same with upshifting, a power shift is just going to send you sideways. I am way easier on my drivetrain with my 505 than I ever was with my Chevy 350.

I definitely would not waste your time on a stock clutch. Ive driven a couple cars with the centerforce and a couple with the Mcleod. I like both but personally like the Mcleod more. To me it has a better pedal feel. I will be running one behind my built 432 that I plan on pushing around 500hp

What ever brand you decide definitely get a flywheel that will accept a 11" disc.
