Replacing the clutch pressure plate and throwout in my 69 427 car. I have used the Hays street strip Borg & Beck 11" kit in every GM car for 30 yrs. Well that kit is crazy expensive now - around $450. Looking for what has worked well for you - for great all around STREET use.

I went to my local NAPA store and bought a Luk clutch. Works just fine.

FYI - I would not recommend using the needle type pilot bearing.

I went with a Hays recently because I've used them in the past. When it came in quality looked like crap looked like a 2 year old did the riveting. I also agree use the solid pilot

I like the Mcleod line up, and presently have a super street pro, but if I were making slightly less power, I'd probably go with the LUK. Its the stock clutch for all the big power cars of the day whether it be a GS 455 or a LS6 454.

Yes I agree on the solid (non magnetic) bronze pilot. "Change it every time you see it" haha. So is there a HD LUK kit or just get whatever they have?

Hays used to have a rebuild service too for both discs and PP, about $125 - both times I did that deal I swear they just sent me a new kit instead of my old parts (the plating looked too good). But they don't do it any more

The McCleod super street pro is what I am using....

Excellent quality....and nice pedal feel....not too stiff......organic/ceramic disc.

Somewhere on here is a thread where Lars did a compression/release check on the pressure plate with an indicator and it was spot on.

I used the same one.

What is wrong with needle baring pilots? You do understand that if you actually dial in your bell housing to less than .002 the the tranny input shaft is not even touching the the baring? I take the time to take a few thou off of the allen locking dowel pins to get as close to "ZERO" offset.

I would never buy a Hays part again. Price has gone up and quality has gone down

I've had good luck with the Centerforce Dual Friction. Doesn't cost much. Low pedal effort and can handle the power. It worked great with my 427 and was able to hang with the 540 until I got past the 800 HP range.

While there's nothing wrong with a GOOD bronze bushing...I've used the GOOD (Lakewood) needle ones for years without any issue.

The Centerforce Dual Friction clutch is a great clutch. Stock pedal pressure while clamping force is good for 650HP or more.

And I use a steel needle bearing that comes with the TKO 600 kit. They don't want any play in the transmission output shaft to the engine

I just installed a SPEC clutch and aluminium fly wheel. They are great to work with the the quality is top shelf.

I had a Ram but that POS only lasted 15,000 miles. It was a stock unit but couldn't handle the HP my modified ZZ4 is putting out.

I remember that Lars test, and thats part of what made me stay in the Mcleod family. That and I couldn't get my hands on the Sachs kit that used to come with the Keisler TKOs.

Truth be told, Im yet to drive my Super Street Pro, as Im in the midst of a drivetrain swap, but I have certainly tested it with my left foot. If I recall the pressure plate is the same as the Street Pro I used to have.

I fully expect this clutch to stand up to my new motor, and it was priced right.

I think its the LUK 4020 that is 11" 26 spline. Are you 26 or 10 spline?

10 spline

sullyman56

I have the same one. Works very well.

I am in the process of putting in a mild(400 H.P.?)small block in my '74. My buddy said the pressure plate was fine but I should go ahead and replace the disc and throwout bearing. All I can find is complete kits. Anyone got part numbers for what I need?

Big Block Dave

Honestly, at the price of that LUK kit, I'd buy the set and have the flywheel resurfaced. It will handle that power.

Richard Daugird

I didn't realize that they were that cheap. That will work with 27 spline M 21?

Big Block Dave

Your M21 is 26 spline, and depending on whether your flywheel is for 11" clutch or 10.5" clutch will dictate the correct model. 04020 or 04019
