Original specs for 478 needed
 
Hi,

Currently in process of assembling my 478, was machined prior, I couldn't find original specs/measurements to base this build on. Does anyone have access or know where to find these?

Thank you

Alexi

crank and rod clearances, I need to order bearings. Or original crank and rod diameters to base my machined parts

Took some pictures of my manual, has all the V6 specs you need including torque values. Good luck.
When you enlarge them they have the proper orientation.
