912 Engine Project Part 2

It takes some time to have all parts together for a nice build Porsche 912 Engine.
This engine will have it all.....
The 912 Crankshaft after polishing looks nice
the new lifter where checked for the cambered surface
Looks good!
The Lifters are all in tolerance but I like to pair it with the rigth lifter bore
New JE Pistons, 2g difference that`s too much for me.
I`m a little disappointed about that, because a high price piston like that should be better in tolerance.
Anyway I brought it to 0,2g ;-)  
AA Cylinder: Measuring the length, the Ø and out of round all where perfect :-)
Backlash and axial endplay of the Camshaft
Good fit of the Rods!
Dial in the WEBCAM Camshaft
The quality and finish of WEBCAM is very good
Just to compare:
 left 912 Pushrod
mittle JPS custom Pushrod for this engine
and the VW Typ1 stock
The weigth of 8 Stock 912 pushrods :-(
That`s too much in weigth and they where too long too!
Ah, 202g ligther than stock!!
JPS Aircooled Aluminium Pushrods for Porsche 912 Engine, you have the correct geometry with the rigth length and reduction in weigth too.
Win win!  
The combustion chamber after masching!
On Porsche 356 and 912 engines the combustion chamber are not equal you have to fix all
The 3. Piece in place with CSP Oilpumpcover
