Ford is a Long pressure plate. GM is a Borg & Beck.

The Street Twin is basically a GM pressure plate with a flywheel that's adapted for it.

It doesn't matter how many bolts hold the pressure plate to the flywheel. Trust me on this one, a Long style plate will have a lot more clamping force than a diaphragm. Again, the number of bolts to hold it on doesn't mean anything.

I have yet to hear your preferences and that's what I need.

Do you mind a stiff pedal? What if it's stiffer than the one you have now? Do you mind a little clutch chatter on a dead stop take off?

I need to know those answers, then let me worry about the clamping forces, the number of bolts to hold it on, etc.

I'm going to use the Street Twin as a last resort, because I honestly think it's overkill in both application and price for you. The ONLY reasons to use it are if 1. You're making 1000hp 2. You're drag racing. 3. You wouldn't mind a stiff pedal, but you absolutely don't want ANY chatter.

Here's how twin disc clutches work: You can get away with a sissy pressure plate because you now have two friction discs. The regular McLeod RST is a diaphragm plate with two organic discs. That means it's going to have a light pedal like a production street car, but it's going to grip....and it will hold about 800hp.

The Street Twin is going to have a 3 fingered pressure plate, and it's going to be stiffer than the one you have.....probably by at least 500 pounds of clamping force. I don't have the exact numbers in front of me, but the one you currently have is a baby pressure plate. So that means that it's not going to chatter because you have organic discs, but the pedal effort is going to be more than what you're dealing with now.

I can get you a brand new McLeod pressure plate, disc, throw out bearing, and billet SFI flywheel for under $700. You're going to pay at least $950-1000 for a Street Twin.

I would set you up with a 500 series disc, because I think you're making more than 400-450 hp. This disc has bronze pucks, so it *may* chatter, but I really don't think it would. I sell a lot of these discs to Cobra guys and I haven't heard anyone complain yet.

I have to tell a lot of people that they can't have their cake and eat it too. If you want a clutch that will hold the horsepower, it's not going to drive like a Honda. If you want a clutch that has a baby pedal, then it's not going to hold 500-500hp.

The RST clutches are much more cheaper, and if they had one for a big input Toploader, I'd be jumping up and down and pointing at it, as they're about $750 for a kit. However, the Street Twin is quite a bit more expensive.
