Ken Hurst is apparently prolific engine builder and is an inspiration to all who have an interest in IC engines. His site with the sights and sounds is a joy to visit and I have shared his 'sounds' with others often.
Wall engines are tried and true and are from here in the USA (Chicago). The Challenger V-8 is also available from a Coles' Casting Set and when completed, is a marvel, but there are many, many parts to that calibre engine even for an experienced builder. There are 'over head valve' heads available for the Challenger (flat head) and a blower.
These engines are not toys, they are REAL engines with real maintenance, problems, and construction expertise required. The undertaking to construct one of these is a great reward when complete (with dilligence) and will be a cherished item to anyone.
I often see a completed engine on ebay and wonder where the builder is; died? The price sometimes reflects an understanding of the dedication required to complete one but usually does not. I have purchased a few model engines on ebay that were runable, trash, and a few worthy of some reconditioning to run again (some never have).
Build your own from a casting set and a set of prints, you can't go wrong.
I'll say this: If an engine 'of proper technique' has compression, ignition, a fuel supply and some lubrication, to your joy, it will run.
