It’s just the completed frame and mechanicals he’s selling. No body, interior, etc. It’s a TC engine not the Zetec he thinks it is. Seems a bit rich unless there is a lot of supporting documentation on the engine and transaxle builds.
The idea for a single Weber is interesting but it would need a “swan-necked” manifold. Those abrupt bends would be flow killing. Also, is there room? The carb might be through into the fender well.
