Oh yes, it's a gem! One of a the very rare engines that came with forged internals as standard. I know, to a person who appreciates originality, it probably doesn't mean too much, but to a modifier, it's a godsend. Even unmodified, it's probably the only engine that can dethrone the BMW / Mercedes pair.
The book's name is "Into the red" isn't it? I have heard of a couple of sound samples from the net. The BRM is absolutely delicious! It's supercharged as well, so it has a really ear-splitting noise that's brutal and beautiful at the same time. Collecting engines isn't a bad idea actually! Although you'll have to have a good test cell to run it safely. But it is a very interesting idea.
