Realistic T4 build. Is it possible?

[rustbucket]

Thanks Yeti, I've got one, and an option on another (1.7 and 2.0 respectively). No disrespect to any of the others that replied, but I'm going to rebuild it myself. I've built several other engines, and with manual and video I'm sure I can do it. I will probably get advice on cams etc though. I'm also going to document the build so if anyone else wants to go the same route in building a T4, the info will be there.
