For those of you who recall the fact that, from this thread, I decided to build a Gurney Weslake engine for my GTD....and the many issues that I had with Jay Cushman who did the initial (poor) build, I am pleased to say the engine is now back in my GTD thanks to Peter Knight at Knight Racing Services and Frank & Jeff at Wealden Engineering, who have put the engine back in, carried out the dry sumping of the engine, and put a new exhaust system in. The engine makes 545 BHP and 531 Ft Lb.
It is on a Dart Aluminium block. If I was ever to build this engine again, I would advise anyone not to use a Dart aluminium block. I had heard that there were issues with them before (and both Jay Cushman and Peter Knight told me to avoid them as they always required a lot of expensive work to prepare them). I should have listened as it was nothing but hassle!
Now I look forward to racing it.
Enjoy!
