What have you done today with your Austin Seven

[Malcolm Parker]

I spent this morning preparing the new engine for the Ulster rep prior to getting it on the test bed.   Whilst looking for a few bits and pieces I found the first of the wedged low comp heads that I did.  This head was on the engine with the pressure fed Reliant crank, fitted when the supercharger was removed.   As wedged heads were discussed a short while ago, I have taken some photographs which clearly show the shape of the combustion chamber.   The CR is in the region of 7 :1.   I seem to recall seeing a photograph of an original GE Brooklands head and the shape of the combustion chamber was very similar.  It is a long time ago so I may be wrong.   For those interested the head is 37.5mm deep on the nearside and 33.5mm deep on the offside.
