New Engine

We were offered a used engine for an acceptable price. It has 3000 miles after being rebuilt. The owner decided it did not have enough power and has built up a 911 engine to replace it.

It was represented to me thus:

  • NPR cylinders and pistons (1720cc ?)
  • A spare set of rings
  • 050 distributor
  • Rebuilt Solex carburetors
  • 10 over on the crank
  • Competition Engineering did the machine work
  • Balanced
  • Rebuilt generator
  • New clutch
  • 4 new exhaust valves
  • New push rods

The fan shroud is in bad shape (and was painted red) and will have to be replaced.

Initial View

Here is the engine when we picked it up. The serial number is 743621 which is a 1965 engine. The case casting number is 92920 (12/65 according to the Maestro's formula) and the engine type is a 616/36.
