Sidevalve replacement

[sevrien]

Hello,

can someone tell me if other types of Minor-engines with gearbox will fit into an original sidevalve-car?

greetings

Simply put, yes.

I believe that new engine mounts are required though and the transmission tunnel may need swapping for a later one (although things can be done to change that) if swapping the engine and box it makes sense to swap the rest of the drive train too.

Good demand for the sidevalve parts - so don't throw them away!

It depends on how old you MM is, if it a lowlight and some early high lights the bulkhead has also to be modified. From about 1951 onwards an A series will fit in without to much effort, tho as Dan says depending on what gearbox you fit you may also have to adapt the floor.

You will need to change engine mounts, gearbox mounts, clutch linkage, engine, gearbox, propshaft, gearbox floor pan, radiator, carburettor, butcher the engine compartment crossmember if the car is pre mid '52 and possibly some other bits and pieces. You will then lose the character of the MM

Hello,

Thanks for the replies.
There was a 1959 Morris 1000 engine with gearbox for sale on ebay.
But seen the adaptions i'll have to make, i guess i'll stick with my sidevalve.

Certainly the car will be much more valuable if you keep it original.

some people are happy to drive the sidevalve minor - by no means is it as practical as a later Minor in terms of speed, but if that is not a major problem to you, then the engines are pretty reliable and pretty pleasant.

Normally I'd tell people to do whatevery they want with their Minor as long as they enjoy it and it continues to get used - however with the MM, if you want the performance of a later Minor, it is easier, cheaper and less effort just to get a Minor 1000. I've run most of my cars pretty standard, and never had a problem - I've had a few with 1275s which is nice in terms of speed, but as I'm really tight I do also like the excellent MPG of a standard car (excellent mpg if it's in good order).

The later cars are plentiful and if you want a bit more performance than that there are plenty already converted to 1275 A-series power. Unless you have a dire need to mpodify your own car, you can usually find most of what you are looking for already done by someone else (saving time, effort and cost).

Wise decision

Performance is no issue.
The only reason i'd like to change the engine is the availability of spare parts in the future.
