Great, thanks guys. I guess I hadn't considered all the implications of having to change everything else. Was just looking for a bit of a short-cut to getting some V8 grunt that could then be easily tuned upwards. Will have to look into some of the other options for the stock engine. Can anyone recommend a good Turbo or supercharging unit/supplier to look at?
Had a TVR a few years back. Was great when it ran, but that wasn't all that often, as reliability in those, particularly the earlier 350 that I had, was through the floor! That's one of the reasons the 350/370 is so great, it's internals seem to be bomb proof!!!
