Which clutch??

Im replacing the clutch in my 71 454. I am looking at Zoom, Mcloud, Centerforce and RAM. Any recommendations? I am also installng a TKO 5 speed at the same time. The car puts out about 450hp /480 foot lbs of torque.

Thanks in advance

I don't see Luk on your list. They are the OEM manufacturer. I installed one in my '69 big block, 435hp and love it. Also have a Keisler 5 speed, but wish I had not used a 3:08 rear end.

I have used Luk and Centerforce on small blocks with nice results. No experience on the others. I would go with something that is OEM equivalent.

Centerforce but watch the pedal freeplay closley and keep freeplay in proper adjustment for the first 1,500-3,000 miles or you will smoke your new clutch.

Another vote for Centerforce DF. No heavy pedal effort, nice smooth engagement, and killer grip.

I have used the Center Force I clutch for years behind my motor and it has been trouble free (and its for sale 5K miles). I plan to use the CF Dual Friction behind the new motor.

Centerforce II clutch. No problems after 500 miles.

Maybe 400 HP, 450 ft/lbs torque. Will find out in the spring on a chassis dyno.

The Keisler clutch is by Sachs- German company that makes clutches for everything, it seems from trucks to cars to F1 race cars. Any experience with Sachs?

Anyone running a Luk Clutch kit? The tech support at Luk states that the minimum Tourque spec for their origional clutch kit for the 454 is 425ft/lb. This is a minimum spec. Not sure why they rate clutches by minimum specs.

I have the Keisler Sachs clutch. Seems to be holding fine with no excessive pedal effort in the 650hp version.
