Sleeved block for race engine

[Ruairidh Dunford]

Hi Stuart - the line in the crankcase was a score, possible from a knife if I recall correctly. The engine came to me like this and was fitted with original rods - these were reused in the rebuild. The fixing adaption to the base of the crankcase you describe would have prolonged the life of this block for sure.

I have cap screws fitted in place of studs in my Ulster engine, which have held so far, but it is certainly not a racing engine.
