[QUOTE="taylorsk8, post: 19109, member: 33"] Don't really want to work yet so here is what I found. Assuming by your name a 69 Corvette. Part 1: 19s780080 1-Cheverolet 9- 1969 (or possibly 1979, :D) s- St. Louis Assy Plant 780080 - Vin Sequence # Part 2: VIN 795780080 Not enough digits - should be 13 not 9 and also doesn't fall into the range of sequence #'s used. I would say you are missing 4 digits in front being 1Z37 and the 5 is an S. Your vin is probably 1Z379S7[COLOR="Orange"]8[/COLOR]0080 However build sequence did not go that high so one of the sequence #'s must be different, say an 8 being a 3 or something. here is what they should mean: [COLOR="Blue"]1969 Corvette VIN VIN Range - 194679S700001 to 194679S738762 Character Position Code Significance 1 1 Chevrolet Motor Division 2 9 Corvette Model 3 4 V-8 Engine 4-5 67 Convertible 4-5 37 Coupe 6 9 Last Digit of Model year 7 S St Louis Assembly Plant 8-13 6 Digit Build Sequence Number [/COLOR] Part 3: P9S25A I don;t recognize this series of nembers at all. Usually there would be a time code stampped into the block with the casting # with the format: V0101HW -which would be V- Flint, Michigan Assy Plant 01- January 01- 1st of the month HW - 350ci, 300 hp, Manual Transmission Hope this helps at least a bit.
