I have been running an engine with a crack in the top surface of the block for years its in the middle running sideways from the centre stud,
I changed the block when it cracked a cylinder, one of the risks using 80 thou oversize pistons at 6000 Rpm
At the price that single seater is a bargain !!!
VSCC would require a change of exhaust manifold to a correct period style.
I suspect that the engine might only need a replacement block.
Talking engine prices, Austins are still cheap compared to a lot of cars. Pistons are not expensive Billet cranks are comparable to modern engine prices ( Mazda Mx 5 pistons and rods are more expensive for the same quality )
Paying an expert to build an engine is the expensive part.
Luckily for most of us the Austin engine is easy to build. ( I built my first one at 16 years old )
My current Nippy Engine build is at £ 6400 in parts so far, That is without any machining work yet.
I bought a genuine nippy engine in the above amount though, The crankcase needs some welding work doing to it before I will use it.
I also have to sort out a set of valves and springs etc and have the block bored.
