Vette(s): 1968 convertible

Hello friends, as you may know I am rebuilding the engine in my 68 (not stock, it’s a 350)

 

My tranny was leaking pretty good so I yanked it as well as to replace the seals – turned out there was zero fluid left and it has the wrong seals installed to begin with….glad I took it to a tranny shop.

 

Anywho, I had the flywheel cut and I am going to replace the clutch – just not sure what to go with and looking for advice.  This car will be driven *kinda* hard on nice weekends, not a driver but also not a strip car.  I am not interested in a soft slippable OEM clutch but also not looking for an over aggressive set up that will jump off the line.

 

I was looking at the SPECS and found them pricy.  I have read good and bad reviews on the Centerforce Dual Friction, and some for Zoom, Ram and McLeod – I would like a Vette owners first hand opinion.  Anyone install something comparable?

 

If it helps I am looking to net around 400 HP, give or take 200 lol – no idea what the lower half of this engine is yet.

You really don't need to go with a high dollar clutch set-up, imho. The stock LUK clutch will handle just about anything you throw at it, until you get into using nitrous, or a blower. The dual-discs set-ups are kewl, but they cost waaay more than they need to, for something that is mainly street driven.

Whatever you go with, just go with a "normal", woven type friction(disc). Carbon, or metallic friction materials will make the clutch jumpy/grabby on take-off.

Make sure whatever you get has the correct spline count for the input shaft of your trans. The early model like yours should be a 10 spline, but ya never know, it may have been changed somewhere down the line. Since you have the trans out, it's easy enough to check which one you have.

Vette(s): 69 Vette.LeMans blue w/383 stroker- AED 950 HO modified carb -Weiand team "G" intake -AFR 210 heads- solid roller cam- 21/2 in side exhaust. Muncie M-21 trans and 4.56 rear. Used for dragracing and cruising,
I have a '69 with a 383. I have the centerforce dual friction clutch. It has a very smooth release and very little effort to depress. I have had it in for two years and I frequently drag race the car and have had no issuses with it.

I second this recomendation...  I am building a stump puller and wanted to make sure the clutch can handle gobs of low end torque.  i have always had good experience in the past with this clutch even in cars where I have been less than gentle (most of them)
