having read this thread it has opened up my eyes to what is involved in engine building. I can now appreciate the time , skill and effort that goes into making a top performing engine. In turn it is fair to say that when people are quoted prices, we can see why.

I still want to have a bash at building an engine, in time i will have a go.

keep up the informative posts on this and many other tech subjects, it does make some interesting reading and can only benefit our fellow enthusiasts
