So the engine code shows it's a 350/295 L48/automatic and the rear shows it's a 12 bolt non-posi.
What is interesting is the trim tag is missing the 4P code.
Here is a quote from the CRG indo: "The 4P code was not used at the start of production at either the Van Nuys plant or the Norwood plant.
Van Nuys started using the 4P code on the SS350 cars in September, but Norwood didn't start using the 4P code until October. Early Van Nuys SS350 cars and Norwood SS350 cars built before October will not have the 4P code to verify that they are SS's
This is looking like you car is an exception to this finding being yours is mid June 67 (Kurt?). Then again, with a VIN sequence of 666 anything is possible
The engine assembly is March 23rd. Early for a June build but it is possible it sat that long. Both my 67 BB's sat about 2 months before being installed.
If you can dig into the block casting dates and numbers (intake, block, distributor and even heads if you want to pull the covers) that would present a clearer picture of what you have.
The June 1st rear date range is good. Is there a rear factory traction bar on this car?
Per the CRG end of month VIN report, the160666 falls in the June period, which is good.
As you can see, a picture can show us a lot!
