That period of road car engine are not very efficient, it's basic design limitations compared to modern engines. You have to change a lot of the mechanical design to increase that efficiency.
When i was involved in the protype new heads from Wildcat Engineering for the Rover V8, we made huge gains over the OEM castings. It's a pity TVR didn't take that on and went down the AJP route, they may well have survived longer and offered a product that wasn't so flaky.
I recently built a 1963 engine with 2 valves per cylinder on mechanical injection, thats pushing 200bhp out of a 1.5 litre NA. That was bleeding edge technology back then. They now make almost 1000 BHP out of the same capacity.

A good rally engine should be relatively torquey, not peak power chasing.
No power below 4k. To pull away rev, dump clutch and spin wheels to avoid burning the clutch out. ETA
More torque than you could shake a stick at just not low down.

A very long time ago I had a 350 YPVS tuned by the legendary Stan Stephens. Power band was between 9-11k. fETA

Back O/T, I bet the smile on Harry's face when he's blasting along on all 12 cylinders will be worth every penny. I wonder if Mrs M has a thread on Mumsnet where she vents about the amount of money Harry spends

Then it's not difficult/impossible to drive.ETA
