Does anyone know when the 392 crate from Ford was originally offered? I ask because, and I may be wrong, but I understand there were some problems with the earlier engines, and internal changes have been made along the way to remedy the issues. The reasom I ask is that I'm looking at a 1999/2000 superformance with a 392 in it, and wondering if this was the time frame for some of the problems that became apparent in these engines. Also, did the block come painted blue from the factory ? Thanks for your help in advance.
