Don't know if the person meant it to be, however when you describe it as an aluminum 427 engine, it seems most people would think they are talking about the block. But what can you expect from a magazine that has a Ford motor on the front cover
Are you thinking it would not have stood up because of the alloys that was used at the time, or because it might not have been sleeved with steel liners? Just curious is all. Inquiring minds want to know. Well I do anyway.
