Need Hyd. tech. help

[treetopflyer]

I'm finally gathering pieces for my Cummins 4BTA swap. The donor engine came with a ford bell housing and a external slave cylinder (sweet!). Of course it's junk, so I'm looking at circle track suppliers for their master/slave cyl. combinations. I figure no more plastic components and lines that can only be purchased at the "stealership". The question is this: I have read that the bore on both cylinders should be matched? But what size bore is sufficient? How much stroke do I need at each end? Are they suppose to be 1:1 or is it a ratio? Any of you hydraulic technicians feel free to chime in/ recommend web links for further research.

No takers? someone must be running a hydraulic master/slave clutch. (I have read the tech article)

Dont know myself but - - -
Check on the ford pickup site under 80-96 ford pickup manual. These trucks use the hydro clutch and they can give you some ideas of this
A long time ago I read about this and i remember 3/4 and 1" bores were mentioned
