Personally, I think we are being far too analytical with this subject. This
is what the official TR3 Instruction Book says:
"New Engines (see "Running Adjustments ")
For at least the first 500 miles, the working surfaces of the engine will be
bedding down. The power and performance will improve only if the vehicle is
carefully driven at moderate speeds during the running-in period. The engine
should not be driven at speeds exceeding 3,500 r.p.m. during this period, and
the " running-in " should be progressive. The engine may " rev." fairly fast
so long as it is thoroughly warm and provided it is not pulling hard. Do not
let the engine pull hard at low speeds, always select a lower gear."
I have always run my engines in just this way and have never had a problem.
The TR engine is very far from rocket science.
