Well, this is a bit of a long shot but worth a try. I'm looking for the original 427 engine for a '68 Impala SS427 that I recently purchased. I bought the car from a guy in WI who purchased the car in North Dakota about 20 years ago or so. It was last registered in ND in 1985. The car is gold with white vinyl top and gold interior. It had a '67 396 and TH400 in it when he purchased it. The VIN stamp on the original 427 block would be 18C113845. If any one has any info or remembers the car, please let me know. Thanks! Steve
