I have this week been putting my Riley Kestrel engine back together with some upgrades. It is a 1967 1275cc unit which a friend Elgin Greer has bored out +20 with Mini Spares pistons. The cylinder head is the big valve Cooper S type and we have went for a Kent 266 camshaft with MED adjustable timing gear. The rocker assembly is MED 1.3 ratio roller type. The crankshaft is EN16T standard / standard with an MED ST1 ultralight steel flywheel assembly all balanced.

The gearbox is a 1128 and we fitted a close ratio gearset and changed the diff from 3.76 to 3.44 and fitted a Mini Spares cross pin diff and Cooper S output shafts as we think it will being giving about 85 BHP at the flywheel. Will keep posting photographs as I progress as I'm still waiting on parts from England :D

That should go very nicely.

I'm running very similar spec 1293 with MD266 cam, but about 1.25 ratio rockers (8mm valve lift). For the twin HS2s, as a starting point I am using QA needles with blue springs (Maniflow freeflow with exhaust twin box RC40).

The one change you will likely need to make is to the distributor advance curve. Chances are you will need to change one or both of the advance springs to get the engine running well throughout the rev range. Would also recommend keeping the vacuum can for road use.

If you're in the UK then Shell 99 octane with 9.75 compression ratio works well for this spec.

I would have gone for an SW5, far more tractable with that diff and gear ratios, the Kestrel is a much heavier car than a mini and you'll notice the difference especially with passengers, more gear changes.
You'll need to use at least 5500 to gain any power advantage with the 266

Just my two penneth

Thanks Carbon and JohnA for your help and advice. I'm still waiting on parts coming from Mini Spares to complete the build. I intend to fit an Aldon Yellow with points to keep the car positive earth for the rev counter. Will continue posting photographs as I make progress :D :D

Installing the flywheel and oil seal with the right tools is child's play. I ran into a problem with the Mini Spares flanges. I had to have the centres machined in the centre to allow the two flanges to meet face to face. Has anyone else encountered this problem :?:

That looks very smart Alan - not much to give away engine modifications....you'd need to be something of an anorak to realise the breathing/carbs were a little different. ;)

Where did that heater tap come from, or is it simply an original that's lasted?

Hello David, had the Riley out for a 30 mile run today and very impressed, I'm over the moon, nice Christmas present for myself :lol: The Riley is finished bar the windscreen washer bottle which is a 10 minute job. Very lively and fast on the road I must say. The roller rocker set also makes the engine very quiet :D :D

The heater valve like most of the car is original.

Here are photographs taken earlier :lol:
