Can anyone recommened a web site that I can do to and educate myself on different clutches for f-bodies? Mainly looking for the difference between like say a SPEC 4 and a twin disk?

 

A twin disc will offer the same holding power as the spec while giving much smoother clutch engagement. Not much more than that. If you've got the money, get the twin disc. It'll be easier to drive.

 

Here's a simple guideline:

Stock power = stock clutch

More than stock power = Street Twin

You can rebuild the Street Twin, and it is proven. SPEC clutches are proven to not drive, last, or perform as well as the McLeod. They are cheaprer, tho .
