Hond0 Posted March 17, 2018 Share Posted March 17, 2018 I have a 1970 SS 454 that I am about to dig into a restoration on. I was wanting some input on my engine pad numbers. I believe the car to have the original drivetrain. The engine stamp is T0106CRN and my partial VIN is listed as 188145258. The same number is stamped on the transmission housing Does anyone know what the 188 means? Thanks!! MIke Quote Link to comment Share on other sites More sharing options...
1970mcss Posted March 17, 2018 Share Posted March 17, 2018 Mike, could your stamping be 10B, the first digit 1 = Chevrolet, the second digit 0 indicates the year, the third digit B indicates the factory "Baltimore". Form what I have read the T***CRN stamping comes from the Towanda engine plant, the date code and crn. The vin stamping was stamped at the assembly plant. I hope another member can verify my information. Quote Link to comment Share on other sites More sharing options...
Hond0 Posted March 17, 2018 Author Share Posted March 17, 2018 It's definitely 188 and not letters. Quote Link to comment Share on other sites More sharing options...

Hond0 Posted March 20, 2018 Author Share Posted March 20, 2018 I thought for sure someone would have an idea on it by now. Quote Link to comment Share on other sites More sharing options...
1970mcss Posted March 20, 2018 Share Posted March 20, 2018 I have been looking on different web sites but I can't figure it out Quote Link to comment Share on other sites More sharing options...
Hond0 Posted March 20, 2018 Author Share Posted March 20, 2018 it seems like everyone I have shown the stampings to agrees they are factory stamps. Quote Link to comment Share on other sites More sharing options...
Canuck Posted March 20, 2018 Share Posted March 20, 2018 I’m sure Darren will eventually chime in. He’s very knowledgeable with this stuff. Quote Link to comment Share on other sites More sharing options...
1970mcss Posted March 20, 2018 Share Posted March 20, 2018 From what I have read, the engine plant put the T0106CRN stamp on and the assembly plant stamped the VIN stamp on the block when the engine was assigned to the car which makes sense. I haven't been able to figure out what the 188 represents. Quote Link to comment Share on other sites More sharing options...
Hond0 Posted March 21, 2018 Author Share Posted March 21, 2018 I heard from someone on the Team Chevelle website that Baltimore often used "188" instead of "10B" as the reason for this. Anyone else have a thought on it? Quote Link to comment Share on other sites More sharing options...
