Steven,
In the thread you mention from start Nov " Alloy Head", I seem to recall
Magnus Karlsson giving some output figures associated with a 100 build (
albeit race) but which was also suitable for fast road.
Magnus wrote:
" I've built an engine with DW full race aluminium head, composite gasket,
300B0 race cam and H6 carbs. I put it in a dyno and it gave 156 hp at 5000
rpm. I don't remember the torque figures but maximum torque was achieved at
around 1500 rpm and maintained as a flat curve up to 5000 rpm. This resulted
in a very competitive race engine and also a very tractable engine that can
be used on the streets without any problems. I would always choose to build
a 100 engine like this as you get a real quick car with the better road
holding compared to a 3000. No problems with water leaks and the head has
been long lasting. Magnus Karlsson"
Hope this helps
Andy

Subject: [Healeys] Increased Horsepower
A short while ago, some listers were talking about getting increased
horsepower in their AH 100's by just changing over to an alloy head with
better breathing. Keeping stock carbs and still getting a great increase.
Does anyone have any documentation as to the actual increase? The reason I
ask is that I have a friend with another 100 and he's thinking of going with
full M mods, (Cold air box, bigger 1-3/4" carbs, new manifold, new cam,
valve springs, etc.) and keeping his iron head. I told him about the talk
here about the alloy head and before he jumps in to the rebuild, I'd like to
pass along some information before he gets too far in to his project. Thank
you all in advance for your information.
