Looking through past threads on this topic there is a fair amount of chat, a lot of which is based on original Austin cranks so rather than looking at piston to head clearance at high revs in general terms such as 20 thou bellow deck height for 2 & 3 can anyone be a bit more specific bearing in mind modern EN40 cranks.
I'm building up a competition engine and would appreciate any help on this.
So with a Phoenix 2 bearing 1.5" splash crank revving to 7000 + what would be the recommended final piston crown to head clearance gasket fitted be. i.e. the actual running clearance regardless of gasket type/thickness. And would this differ for pistons 1 & 4 and 2 & 3?
