Currently the car has a Cosworth BD engine fitted so running the car is not an issue. What I want to do is to return it to originality and then race it as it would have done in period. The bulk of the engines racing in the F2 series are either Cosworth or BWM so it would be good to take out something that is a little differen. I appreciate that in period they were underpowered but I can live with that if I can get one. If I am going to do this then it needs to be exactly the same block and head used in period (and I willalso need the evidence to prove it in order to get the appropriate papers for racing) It sounds as if the block will not be the problem but the head may be a different matter

I've just joined the site having picked up on these old discussions from 2009. If at all possible I want to try and build a ROC F2 spec engine so would be grateful if anyone can give me some information about the N9T engine and it's history (prior to finding this site I didn't even know what donor engine ROC had used In period which probably gives you an idea of where I am starting from.) The reason I want to 'source' an engine is because I have one of the ROC F2 cars from the 70's.
