Re: Numbers Matching

If you have a date-realistic engine with the correct casting, that's as close as you can get. But consider my 1970 396 TH400 truck: the engine is coded to 1970 396 automatic truck, so it's a pretty safe bet that it's the original. But you can't prove it authoritatively, even with GM of Canada documentation.
