Engine assembly 3.

Engine.

The Cooper "S" engine was a miracle of its day. The power to weight ratio of the car was more than reasonable. Although 50 years have passed since that time, the engine is still up for its job, although can be improved at some points. The car will be a daily runner, so the most important factor is reliability. Most of the non-original items work in that direction, but we also would like to see a tad more power (as always :-) ), from the engine, if possible.

New cam bearings, hand honed to finish.

Cleaning the crank journals is very important task. Not to be overlooked.

This is the original nitrited EN40B "S" crankshaft. It is in perfect, std/std condition. It was a dilemma whether to use it or replace it with a "mundane" item. But finally the decision was made: it was meant to be used so it will be used :-). 

Some bushings in the gearbox were replaced now.

To be on the safe side, some bearings also.

Checking the end flow here is vital.

Just like using cam lube on the new camshaft.

Isky followers are the best for the task.

Timing in the cam may take a couple of hours. I used offset cam keys to set the timing.
