[TR] TR4 Engine Specs

[Bob Nogueira]

On YouTube I saw a guy rebuilding a TR4 engine. He had a sheet which contained the bare specs for block and Crankshaft without the bearing shells.  My manual shows only the clearances and crank journal size
But not for block. Anyone know where I can get a copy of the block specs on line?  
I’m looking for the size of the thrust bearing  surface before the shells are installed.
