I am going to change my clutch these are the questions I have

1) What ype of clutch should I go with? I have a 69 Camaro about 425 horse. I want my pedal soft - I do not want a racing clutch.

2) My rear seal is leaking, I now the time to fix it?

Tommy,

I have a Centerforce Dual friction behind my 427 BBC. I really like it. It has a standard looking friction material on one side and a puck type on the other side of the disk. I works quite well and the pedal pressure is pretty good for a performance clutch.

I would fix the rear seal now if you can.

You want the Centerforce 2 or dual friction setup. The DF gives more of a quick lockup as it has one side of the disk with a more aggressive material on it. The Centerforce 2 is probably better if you do more street than strip as it has conventional friction materials on both sides. I run the DF behind my 302 and it is a bit more aggressive than I would like. If you have any torque at all, you would probably be fine with the DF. It's just the total lack of bottom end that makes the DF marginal in my particular aplication. If the DF ever wears out, I will go with the Centerfoce 2.

Thanks guys, from the homework that I have been doing so far it looks like Centerforce 2 is the way to go.

In the process I plan on resurfacing my flyweel and changing my pilot bearing to a roller needle or ball bearing type.

I have the 10.5" CF II. Call them up and request the part number for a higher HP rating for the disc. This will be from a heavier car. I told them I was looking at mid-450 HP. The regular part # is rated for 400 or so, I don't remember specifically. I don't think you need a roller pilot bushing, myself.

Why not a roller pilot bushing?

When a roller bearing goes, it can tear the crank up.

There is no performance advantage to running a needle roller bearing. There is less tolerance for misalignment with the roller bearing. The roller bearing can not be removed by using the wooden dowel and chassis grease method. basicaly, the bronze bushing is just plain better. ;)
