I had seen your engine Paul, and it would be great for what I want, but is too good for what I want. I think it is worth what you asking, but it is more than what I can pay. Probably not helped by the courier aswell. Thanks for the help though, and I hope you get a lot of interest.
I have had a few offers of ailisa craigs, am waiting for them to get back to me with prices. I think these would be good for what I want as they are aircooled (with no impellors etc) and hopefully cheap. Only problem is I think they are 25;1 mix, and so will probably need there own tank.
