I know what you mean about running in. When I had my shitty engine fitted last year, I just wanted it done and running proper power. I did 1000 miles and ran it in within a 5 days LOL.

It will be all the "little things" that end up making a big difference to the looks of it all. I don't blame you for not showing under your bonnet if you are not happy with it. I will be the same, as I know (apart from the paint lol) the engine bay will be abit cack looking.

I wouldn't mind swapping with you, because then I get a nice car to drive, and no labour bill from Damo
