Re: The most "significant" Chevrolet performance c
L88vetteron,
The L-88/ZL-1's used a special clutch assembly with these part #'s flywheel 3866735, pressure plate assy 3886066 & clutch disc 3886059. Which is a single plate 10.4 inch, not the 11 inch I stated incorrectly above.
The MA-6 HD dual plate clutch design used two different set-ups one for 427 usage with L-71/L89 and one for 454 usage. '69 application was flywheel 3955151, pressure plate assy 3959175 & clutch discs 3959176.
'71 454 application was flywheel 3992094, pressure plate assy 3993814 & clutch discs 3993815.
There also was a special pressure plate for these dual plate clutches 3955148, this was a unique floater plate used with both dual plate clutch applications, 427 & 454. The flywheel differences are due to 427's being internally balanced and 454's being externally balanced. The clutch discs are also different due to the '69 discs using 10 spline thread and '71's using 26 spline thread.
