I'm interested in converting my LT1 T56 to a hydraulic T/O bearing (McLeod PN 1400-22), and I'm told this works with an '86-'92 305/350 1-1/8"x26 spline clutch. The guy I talked to is running a single disc SPEC Stage III, but I'd like to run a Street Twin if possible.

What I need to know, if anyone has the information, is what the dimensions are (height if laying on the ground, depth when installed) of the 3rd gen. push-style clutch. The guy with the SPEC clutch says he adjusted the spacer collar on the T/O bearing by about 0.25" to achieve the right engagement with the pressure plate, so there must be some extra room in an LT1 T56 bellhousing.

What I really need to know, if anyone has one or knows the dimensions off hand, is if the McLeod Street Twin for the '86-'92 cars (PN 64004-1A-07 w/steel flywheel, PN 63004-1A-07 w/aluminum flywheel) is the same height as the stock single disc clutch or if there's any difference or modification involved.

Thanks for any information you can give me!

 

I would think if you called them they would be able to give you the specs on it. I have a Centreforce, sorry.

 

I've had trouble finding anyone who is capable of answering my question, so I was hoping I could compare the dimensions of a standard single disc clutch and a Street Twin for the same year and get an idea from that. I may just have to buy the clutch and find out for myself.
