Hi Cole, apologies, a bit slow getting on to this. You are correct about the rear anti-roll bar, it is a period Speedwell model for hydrolastic minis. They made a similar one for dry suspension, with different outer attachments. Fantastic project, looking forward to more. Cheers

So cool. The original owner was an absolute rock star. Drag racing, ice racing, what more could you ask. My folks and the owner and her hubby were friends since elementary school. The dad's had quite the pedigree from sneaking away from home to attend F1 racing at Watkins Glen on the old road course to club racing, camping at the races and all that. They were big fans of the little British sports cars for sure.

Hi Cole, nice job with this video and looking forward to following this series. You asked if any small things that viewers noticed could be pointed out. I think I saw the EN40B marking on the crank web, which would mean it is one of the best ones, and possibly is cross-drilled. Post the markings here and I can tell you more. One thing to point out also is that the Cooper S blocks had removable tappet covers on the back like small bore Minis and unlike the solid-back 1300 or later A+ series. Also, the head has 10 studs and one bolt instead of the 9 studs of the other Mini engines. Hope these are useful.

Looks like a great project for you. And enough to show, not just the "normal" rebuilding with new parts but refurbishing the original parts and making it almost as new. Does the owner have performance figures of what it used to have and does he have an goal as what it will have to have again?

@midgelambert3880 2 жыл бұрын

Hi Cole. I noticed as you took parts off the engine you just seemed to lay them down on the floor. Wouldn't one want to catalogue parts as they came off? ie. wouldn't you want the same pistons going back in the same cylinder it came from or does it not matter?

@classicminidiy 2 жыл бұрын

Hey I normally take everything apart and then inventory at the end however regarding your cylinder/piston question. The pistons wont be reused since the block will need a bore, normally I mark the connecting rods as they come out but these are all numbered from factory. :-)

The front plate is off an 1100/1300 not a mini. and the box is from the same car The plate has not been modified to take Cooper S timing gears which is quite fortunate as it is fitted with the wrong timing gears and chain,single row instead of duplex.You have to counter sink the 2 screw holes behind the lower timing wheel to fit the 2 countersunk screws needed for clearance

Yes after some further investigation it appears this timing side also came from the engine that donated the gearbox to the Cooper S block. Will have to be corrected during reassembly.

@roberthatt419 2 жыл бұрын

@@classicminidiy As you say, the timing chain and back plate are from a different engine; in the UK the Austin / Morris / MG 1100 / 1300 range had an additional forward facing engine mount on the timing gear backplate to limit the engine's fore and aft movement.
