Porsche 917K (MFH): Engine Part 2

The engine is now as far along as necessary prior to inserting into the chassis. 


The throttle linkage, including the connection to the injection pump, was a particular headache in large part because, as with the 908/03 I finished a couple of years ago, the return spring is too long. And given it is a real spring made of spring steel, you might be able to cut it, but you won't be able to bend a new eye-hook into the end.

Little venturi ends and injectors will be hidden in the final installation.


Belt drives for the alternator and injection pump are not likely to be visible, either.


The exhaust of the 917 (above), along with the separate distributors, shows the crank is set up as a pair of inline six-cylinder motors on a common crank. The 908 (below), on the other hand, is clearly a pair of flat fours end to end.


On to the chassis now; stay tuned!
