I'll be fitting an 01/02 LS1 engine and box to my car soon, but need some info regarding these items.

My car already has a hydraulic clutch adapted to it with a, but I dont know if the master cylinder will move eniugh fluid to operate the new clutch.
I think my master cylinder has 3/4" bore, but it may only be 5/8". I havent checked yet.

What is the bore of an LS1 mastercylinder ? and what sort of stroke does it have ?

I need to know how much fluid I need to move to operate the throwout bearing properly.

Cheers, Stevie

it's either 3/4" or 13/16" I had heard the 01 / 02 was larger bore (13/16") but have never confirmed that. Stroke is dependent on pedal travel; I'd say more but I don't have my notes from when I last mocked up an f-body master in something else.
