Well thanks to all of you. I did speak to RPI who said that they could easily put an eight into my 89 Plus Four and have done one already. To sure that is tempting because I have upgraded everything else and an engine change is a way forward.
Anyway at the risk of boring everyone else we'll stop now and I will say thanks again to everyone who answered. By the way John, the roadster IS a possibility but I do like my car.
