Hesketh,
There are original engines about and any 2 litre unit will fit a 405, the limitation to performance of the 85 series engines is reckoned to be the diameter of the crankshaft bearings but the FNS engines were based on these units so they can't be that bad. Truth is some of the engine castings were not that clever so for example cracked or porous blocks under the exhaust manifolds, this is by no means the end of the engines life, there are so many cost effective options to keep the car on the road. 85 heads can have seats re cut and enlarged to 100A spec, I am told 85 blocks can be modified to accept 100 series style cranks so a lot can still be done but at a cost. Consider this, the late Brian May and I were discussing 85C vs 100A performance a good few years back and his view was on modern fuel and modern road conditions you wont notice the difference. A 110 engine ex 406 would be a good upgrade if you can get one and if I am able to sell my 401's I will have at least one 85C engine, and an 85c block, crank, cam and 100B cam available, but only if the cars sell first. Geoff.

Hesketh. If I might just add to what Geoff has said about cracked blocks. You might find someone who thinks their engine is good only for spares but I have had impressive results with cast iron stitching. I went to Stitchweld in Burton On Trent with a 1926 Dodge Brothers side valve block. They not only stitched up the water jacket (easy) but also managed to stitch across a cracked valve seat and machined it back to as good as new.
The cost was very reasonable and the repair was a long term success. If you are pushed for cash you could always repair a simple frost crack with Belzona. It's amazing stuff! Don't forget, however, that where ever you can see a crack in cast iron there WILL be another crack or two probably hidden and running above and below (parallel) to it .

Geoff,
you mean any 2L Bristol engine ? or any 2L of similar age in other British cars ? i would be interested in one of your engines if i haven't found one by the time you have sold your Bristols, could i put an auto gear box on these type engines ? Only reason I ask is that I want my father to drive this Bristol and he finds auto gboxs a hell of alot easier ! Raymond, Thanks so much for the company i have added them to my favourites as they may come extremely useful ! Your so right, there will always be one or 2 more hiding around the corner ! Best H

BMW 6 cylinder engine from the 1970s Twin carb. 2.8 litres
One on Ebay that may be recoverable for about £500. Item 265406626599 These were canted over in the BMW but should work upright with a re-worked sump and oil pump pickup. I imagine there was an auto 'box for them.

Hesketh,
I do mean any 2 Litre Bristol engine and the 2.2 litre 406 unit, the changes in mountings on the engines and gearbox ( both Bristol ) came about when the overdrive units were introduce so if you want to fit a 406 engine and overdrive gearbox into say a 401 then the crossmember behind the gearbox has to be modified. If you want to fit a later overdrive conversion using a smaller overdrive it does not. To date no one that I am aware of has succeeded in fitting an automatic gearbox to a Bristol 2 litre engine and indeed after Toby Silverton lost control of Bristol Cars the new owners found themselves at the wrong end of a very expensive legal action when they said they could but failed to deliver such a beast. I don't recall any discussions on this but I wonder if any BMW 328's have ever been fitted with pre selector gearboxes if they have and you can find a gearbox it may be possible to fit such a unit to a Bristol plus assisted operation of the clutch, you could well be entering uncharted territory but it may be fun! Geoff.

David C,
I wouldn't mind that BMW E9 engine in the 405 ! Sounds very interesting fitting that in the 405, but i'm just worried about fitment in the engine bay ? It may be a little to large i am thinking ? Geoff Kingston, Okay ill scrap the auto box on this one ! He can drive the others lol ! The thing is finding the 2L Bristol engine is quite hard and if i do see one they are very expensive ! Ive seen this 405 with a 2.5L Triumph TR6 TC engine and O/ drive gearbox And it looks like it's a good fitment for the engine bay. https://www.carandclassic.co.uk/car/C1373039 I may look for one of these and stick it in the 405 for now until I find a 2L engine thats in my price range. Best, H
