So now he's got his nice wheels it's time to give the little old chap a bit of pep

I had a bit of Mini stuff laying around so I though it might be better put to good use.
A 12G940 un-leaded head with nice big vales off my '91 Cooper ( replaced with a stage 3 head) was dragged from under the bench and cleaned up and the valve face to head face distance measured. The inlet valves had plenty of clearance but the exhaust valves were a bit short of the magic number of .320". As the clearance problem was only with the exhaust valves, and there's loads of meat on them, I decided to trim the valve face back to give the desired clearance.
Still plenty of meat left even after skimming
Now clearance ranges between .322" and .325"
I decided to use a HS4 1 1/2" SU and fit it to the manifold I nicked off a Mini 1100 engine I just happened to have kicking about. A couple of advantages in that it holds the carb at the correct angle and the existing exhaust fits straight on. Eventually I'll need a new exhaust and I'll upgrade further fitting a larger bore pipe but need to find a matching manifold (Midget?) to go with the alloy inlet manifold I already have.
While I was at it I fitted a crank shaft damper pulley.
New head ready to fit
Old head
I had to use the 1098 rocker assembly but this needed attering to suit the 1275 valve spacing
You can see in this pic how the rockers don't line up with the valve stems
Some rockers needed packing away from the support pillars with washers while others needed filing down to position them. The end ones just needed the tension springs fitting on the opposite side of the rocker.
I opened up the exhaust manifold to match the ports on the head
As he was
The new installation
Because of the angle of the heater valve connection on the 1275 head I had to file a little edge off the heater valve so that it would clear the engine steady only to find it fouled the battery when I tried to drop it in

Nothing for it but to pilfer the heater stub connection off the Cooper, I've nicked a few bits off it over the last few years - I should have made a list
And so after initial set up I took him for a blast up the road - a bit disappointing, but after a few tweaks on the mixture screw I got him running a lot better and much nippier - but I think I need an AAA needle as the one fitted seems a bit lean. The only problem is the noise from the K&N, for my daily driver it just doesn't seem appropriate so I've since fitted the Mini filter box and added that wonderful 70's tuning mod - a series of 1" holes bored into the side of the air box

Sounds much better, a nice low growl instead of the K&N's howl.
