The 1970 413 WILL be an industrial engine and is not well suited for a car for several reasons. Even if it's an earlier passenger car engine that was installed in a 1970 car, it will have its own difficulties that you won't find with a 383, 400, or 440. I'd only consider it if were an earlier engine (1965 was the last year of the pass car 413) and was running good.
