I just bought a 1968 convertible, it has a 396 turbo 400 with console and gauges and tic tock tach, build date on the cowl tag is 03c, the rear end is a 12 bolt marked bz, cast date c 21 8. The heads are 3931063, the block has been decked but you can see a Y on the front pad. The block cast date is d 20 8. The rear axle is a 273 non posi would this be correct for a big block?
Is this a real big block car?

Well, to answer your question we need more information, but the quick and dirty answer is maybe!

In 68 the only engine available with the Turbo 400 was the big block, so check the transmission for the VIN. HERE'S where to look (specifically THIS picture).

The BZ axle code is indeed a 2.73 non-posi, and that was the "standard" ratio for the L35 (396/325) engine, and the "economy" ratio for the L34 (396/350). However, it was also the "economy" ratio for the L48 (350/295) and the L30 (327/275), so that doesn't really prove anything. I'm going to assume the car ISN'T a Rally Sport... Also, the C218 casting date equates to March 21st, 1968 and is a little close to a 03C build, but not impossible, depending on exactly what day of the 3rd week the car was started. What's the complete axle tube stamping? (Information where to look HERE.) I'm also assuming your car was assembled at Norwood... What's the VIN?

The block date (D208) comes out to be April 20th, 1968 and is too late for your 03C build date, so it's not original to your car. The 3931063 heads are 69 only, so they're also not original to your car.

Post a picture of the transmission VIN stamping, and if you tell me the VIN (email me if you don't want to make it public), I can see if your car is in the database.
