To bad you are on the wrong side of the pond. Over here, a Pontiac straight 8 is not to hard to find. And straight 6s are a dime a dozen, although I would want a Dodge aluminum Slant 6. A few young Hot Rodders are rediscovering the Slant 6, they really sound great with minimal muffling!I am in the process with the same chap who built this in starting another replica of sorts. However, mine will only be a 4 cylinder special, as the 6 cylinder engines which this replica has are not very plentiful and the straight 8 engines impossible to find. I have a chassis, engine and running gear, which is the first part of the project. It will always be a special, but, being that the last original sold for 750K, I can not see me owning an original! I am restoring all the mechanical parts and he will produce the body.
