Then you don't understand the charm of the 407 / 408. It certainly doesn't need tuning ! In fact Alan Blackwood owned my 408 back in the 60's and moved it on from fear of the speed and the law !! Alan is a fast driver and has been involved in motor sport / rally driving for a large part of his life.

The engine and gear box kits are readily available and I don't think people would be so keen on the idea if it was a Bentley or an Aston ! There are a lot less 408's runing than either of those marques.

We can all do what we want to our own cars. I guess it depends on the motivation and the circumstances and if there is anyway back for the next owner.

If you want a tuned 406 , get a 407 , If you want a tuned 408 , get a 411 S1

I guess there is a very blurred fine line between sensible upgrades and .........

I love the buttons :-)

As I stated the block is porous at No7 cylinder.
To resolve that is not such a simple, or cheap task! Added to this is that my cast Iron box is leaking and will also need to be rebuilt.
As newer 318 engines are not compatible with the older cast iron box, things just compound themselves. I have a Chilterns' manual for the engine/ box, but there are nuances when installed in a Bristol, this is why I asked for a copy or loan of a Bristol manual.
I don't intend disposing of the origonal engine box, but will investigate rebuilding them.
I agree that the push button change is great, I will look at retaining, but have my doubts initially.

I think I remember seeing something on the Imperial owners website about making newer boxes work with the push buttons and fairly sure ACCS have some experience.

I will let you know if I find the relevent info

My comments are certainly not meant as a critisism. Hope it all goes well.

Phew , found a conversion supply company to keep the buttons

No offence taken, ordered the engine mounting brackets today from Brian M.
Thanks for the website.
On looking at the conversion kit, the key seems to be the length of the bracket attached to the gearbox, to match the travel with the dedent positions.
I'll look at the gearbox and see what I can work out.
I agree that the push buttons are nice and neat compared with that hulking great lever
