Original L-48?

[lasereye]

Long time browser, first time post. I have a since new(family)X-55 car; Vin 9N648878, 05D build. It's everything I wanted since I can remember, ( born in '69).I have the POP and everything checks except the motor and rear-end. I never found the rear-end codes but the POP says BV0501G. My uncle(original owner) says the only option he ordered was the Z-27 and U-57, so the POP must have been a mis-stamp 'cause all I could find was that rear-end was special ordered and only for a four-speed. Not a big deal, I'm sure they meant BM. ( I'll find the true code later)
 My real heart breakin' question is the motor, which at one time was rebuilt. The front pad has no stampings accept B U N K .

I shit you not.

The block is a 010 motor. I'm having trouble finding the build date cast, to help on the originality. Where is that?, for starters.
My NOR date of 05D seems to me that the partial VIN would be by the oil filter rough pad. I can't see any thing.If I ever find the partial Vin that matches it would still be a No. matching Camaro, right?, reguardless of the bullshit joker stamp.
Could the block been changed in a rebuild?? Is that a machine shop stamp for "don't use this block" ?? Thats what BUNK means to me...as in " hey, buddy, that acid you sold me was BUNK!" 

 Any help would be much appreciated

Some 69's have the vin stam in the rough casting area near the oil filter. It can be very difficult to find. If the block was decked with the rebuild, any info stamped on the pad is probably gone.

Tons of info on the main site (outside of the forums). Click on the red logo at the top of the page.

Been to the Red Zone many times over the years, I need to know exactly where to look for the cast date. This car is complete and in my garage.Can the cast build date be seen in a installed motor??Lots of crude....but not so much on the oil filter pad...yet still can't see anything. Rough cast...yes......looks Chevy orange...yes....evrything else is dead tits nuts.

the casting date is at the rear of the motor behind the distributor where it bolts to the trans. the trans vin stamp for an automatic is the top of the trans case near the 010 casting on the block.
good luck

My guess is that BUNK stands for BLOCK UNKNOWN.  Like I said that's a guess. The block is known. it's the application that's not.

Found the casting date,  D 28 9.  The POP build date says T0512HB , I would say thats right on. Hope to find the partial VIN one day.( Can't see anything with it in the car). The car is too original to think it's not its block. Thanks for the help.
