Oh - and thanks for the calculations Rich. It all does make sense.

one thing to consider is this

if it was a 2.9 that was used, someone may have miss read the hand written notes and thought the '9' was a '4'

the reason I say this is that one of my French customers has a really strange was or writing the number 9 that makes it look more like a sort of 'y' shape that makes it look like a '4' - it may be that French children where taught to right numerals in this way at school in the 1960's?


next time I see one on his order I will take a photo for you!

That's the point I was trying to make earlier a hand written 9 & 4 can be easily confused.

Good point, could well have been the case. I don't know. 2.9 definitely makes sense to me now.
Oh, and, Al, I think that's a diff ratio one can live with quite easily. Am I right Rich?

Just made a little update on my weblog with some photographs of the surviving fuel tank and the pick-up points for the roll bar.
Have a look if you like here: http://maximummini.blogspot.com/2016/12 ... cos-3.html

Well… I know it reached 141 mph and revved up to 8,000rpm…


I think the '66 Mini Marcos was clocked at 146mph down the Mulsanne Straight?

All depends what you are going to do with it Jeroen. On a road car a 2.9 will make a great motorway muncher but if you combine it with a lumpy cam you could have a car that is very sluggish to get away from standing and a bit of a cow in traffic! Sometimes compromises to the original race spec are needed when you are restoring a car like this, unless it's going to be racer again?!

Many years ago I remember having a conversation with someone at Longmans about the Mini and the Metro (you can tell how long ago I'm talking about!). He said to me that whatever they did to the Mini they couldn't get it to do any more than about 108mph out of it. He went on to say that at the time they were getting 120mph out of the Metro.

Back to the Marcos (that 2nd pic is the '67 one Michael) are there any interior shots Jeroen? Usually the hard one to find!


Thanks Pete for clarification.

As Pete has already suggested what you finally decide to use FD wise should be determined by what you are planning on using the car for NOW, not what it had then. If you are building it totally back to 1960's spec then fine, use the original 2.9, but if you plan on driving it on the road be prepared to COMPROMISE!

Things like actual engine spec & FD are important to know as part of the overall story, but they could make the car pretty much undriveable on anything but a race track. A little bit of compromise could leave you with a truly great historic car that is a joy to drive anywhere & can be easily converted back to full historic race trim by swapping the engine.
