Thanks for the warm welcome.
It's not actually going back into the same car, i'm putting it in a dodge viper replica that i'm building and as i'm fitting everything new as regards suspension, brakes etc, thought i might as well see if i can get the engine refurbed while i'm at it.
There was nothing particularly wrong with the engine, apart from the oil light flickered on at idle (???) and it's done about 134,000 miles, which probably isn't a particualarly high mileage for a v8, but as i shouldn't have to touch anything else on the car for about another 50,000 miles once its completed, i'd like the same to be true of the engine and gearbox.
