Deejay, I don't think 60102 engines or new parts for them are difficult to get. I'm not even sure they've stopped making the engine itself. As long as tezza98 is intending to do a restoration, not a rescusitation-and-tidy-up, I personally think it needs to end up with a 60102 on it (preferably one as nice as mine, which seems to have run very few hours.) I'm not saying the Honda isn't at least as good an engine, and more modern as well, but it wouldn't be original. I never really approved of the popular practice of putting Chevrolet V8s into XJS Jaguars in place of that appalling Jaguar V12, either. Yes, the Chevvy was a much better engine and made it a much better car, but it ended up a mongrel.
