964 engine dimensions
 

I am looking for some engine dimensions of a 964 Porsche engine... obvious things like stroke and bore size are often mentioned but things like conrod length etc. are not as common.

The dimensions I'm after are:

- (1) Connectingrod length (heart to heart) and big-end bore size (2)
- (A) Engine case width (where the cylinders mate with the engine case)
- (B) Size of the bore in the case accepting the cylinders
- (C) Bore spacing of the cylinders (heart to heart of the cylinders next to each other)
- Valve diameters of a N/A engine (inlet and outlet)

Picture to illustrate the requested dimensions:

I only found one statement for the conrod wich said it was 5" (127mm)

The rest I haven't seen anywhere...

Anyone got any answers to these dimensions?

/\ bump /\

Okay, so how about size (A), Case width from left to right where the cylinders enter the case (mate...)

Please, I really need it for an engine project...

In older engines the B dimension was 97 mm (up to 90 mm cylinder bore/2.7 l - when stud pattern was 80 x 80 mm). I don't know what is that dimension in newer engines with 86 x 86 mm stud pattern
