My take was how much will it cost to build an engine from scratch with parts that improve the parts you'd ditch from a complete SIL engine or parts that you'd need to buy that are an improvement, ie, the engine mounts and the crank you listed, but without going overboard on exotic parts like 7 plate clutches and 5 speed gearboxes, etc.

Before we get ahead of ourselves here boys, one question? Have we got a full and/or useful tool kit to do the job in hand? Because if not, ching ching, and there's no way anybodys borrowing my plug spanner before we bloody well start, as I never got me last one back! 
What's the general opinion on these layshafts, any good for 30hp+ engines? Any other options except for the MB?rosscla wrote:Layshaft, restos

buying loose components is not the cheapest way unless your building something quick with lots of special and uprated parts.
good cheap engine will cost around £1300 then after this the skies the limit!
i bet i'm close,i do note some prices quoted are cheaper than cheap and you should be taking an average price on these parts as some areas/shops may not be as cheap!!
