Default T56 swap need a bracket.....

I just bought a 78 with a missing 4 speed. bellhousing clutch flywheel and gearbox seems to have all walked off. Long story short I think they were stolen... I have the orginal motor and all. Linkage pedals and shifter are still in the car. Anyhow.........

I have a complete vortec headed 350 bolted to an lt1 style t56. The plan is to drop that in the Vette hydraulic clutch set up and all. I read on here somehere that the Master Cyl angle will be wrong as it connects to the clutch pedal. Somone made a bracket to correct this and Im wondering if theses brackets are for sale somewhere or if theres a picture with some dimensions floating around?

Thank you!

My template is out there somewhere. Search Budman78 or BudmanLS1 and it might show up.

A clutch master cylinder from a 1985 1-ton truck fits in at the right angle. You will have to shorten the rod and make it adjustable.

Just cut a piece out of the middle of the rod, thread both ends and use a union piece like you'd find on a turnbuckle.

Make sure the bores size and stroke of the truck master will work with the throwout bearing you are using. I think the truck master is 11/16"

The gold rod is the uncut master:


Cut (other end not attached)


And installed (two bolt holes need to be drilled in the firewall as well)

How is the clutch feel with that angle? Seems pretty steep. Mine was pretty stiff, but I was ran a Centerforce clutch.

I have a Centerforce clutch also. The shaft of the truck MC actually lines up straight with the pedal. The clutch in my car works really smoothly. My kids complain that it feels almost too smooth.

Wagner part#CM110273
Cross reference that part number with a Duralast master cylinder... The
Duralast uses a thicker rod

No, sorry. That slave is the one I used for my setup with the stock fork/bellhousing/trans (stock Chevy 1 Ton slave). Are you using an LT1 T56? Why not use the stock slave cylinder?

Currently I am trying to use the stock slave cylinder with the 1 ton master cylinder my problem is I can not find anyone to make a custom hydraulic line to connect the two together. The master cylinder uses the typical screw in type line and the slave cylinder uses the push in and pin deal. Anyone know of a place to get a line made?

I bought a kit from hot rod hydraulics for my other car with the LT1 T56... They supplied an adapter for the slave from the push in pin to AN.
Maybe give them a call and see if they will sell you the adapter? Otherwise find a hydraulic line shop and see if they can get something for you.
