What is the best LS1 Clutch?

[UNGN]

My 2+2 T56 is going need a clutch at some point in the near future. I'm currently running a Ram 98931 LS1 clutch with my 502. What is currently the best LS1 clutch setup and why?

We're running the GM clutch for the LS7 on my brother's car. I don't know that it's the best out there but the LS7 was rated at 525 HP so it can easily handle his 6.0. What is your power level?

Probably about 525 HP with 580 lbft of torque. Its a ZZ502 with pocket ported heads and minor upgrades.

The higher torque of the big block is the only concerning issue, but that is a good price compared to my current clutch.

I had a LS7 clutch in my C5 Z06 and it made 478rwhp and 448rwtq N/A, it held up great! When I boosted it i went with the Mantic 9000. Also you wanting a single disc or twin disk? And what price range? The Mantic 9000 is an amazing twin disc clutch but its not cheap. Also might check and see is Katech still has the LS9X clutch. Its a great clutch for the money i hear. And i always had good luck with the McLeod, check out the McLeod Street Extreme.

Perhaps I remembered the HP rating of the LS7 wrong. I wanted to look up the advertised torque output so I got on the Chevrolet Racing website. It says 505 HP and only 470 ft. lbs. With your engine making 23% more torque, that production clutch might not be a good choice. I wonder what the C6 Vette guys like to replace the stock clutch with? What about an LS9 clutch? It's twin disc so I have no idea if it will fit or work with your flywheel/trans/slave. The LS9 is rated at 604 ft. lbs.

Many people overlook ACT. They have street use all the way out to full race applications. I've personally used their 6 puck race clurch on a highly boosted 300z with excellent results. It's my first choice once the new trans goes in. just food for thought.

I'd also be concerned with the rotating mass in the BBC having an effect on clutch selection.

Monster Stage 3.

I'm curious as to how a LS Clutch is beind a BBC...

8.1L is a big block. Technically the ls7 is also.

GM 8100 Vortec is a MKVII BBC, yes. The GM LS7 Aluminum 427 from the 2006-up Z06 is not a BBC, it is a Gen IV SBC.
