Looking for a 1970 olds 455 block with the date code 30Mxxxxx on it. Just need the block but will take the engine as well

I'm in St.Louis but will go as far as 600 miles to get it.

 

That's not a date,that's the VIN.
When was your car built?

 

The engine block will have 30M followed by 6 digits. I have a 70 olds 442. I know its not the vin. My vin is 344670Mxxxxxx.

 

507olds is correct, the 30m is the start for the vin

 

The 30M is how they stamp the VIN on the block
3 = Oldsmobile
0 = 1970
M = Lansing(or whatever plant your car was built)
XXXXXX = the last 6 digits of the VIN on the car.

The transmission is stamped the exact same way.

There is a julian date on the back of the block,directly next to the distributor hole,which indicates the date of the year it was made. 295 = 295th day.

 

way down here in texas... more then " 600 miles " ... but i have both a 72 julian dated block and a 1970 . The 72 block is cleaned with a std bore and the block from the 70 442 is not so good; needs a sleeve and most likely punched .30 over. If 70 is what you are after I can get you the actual day stamped near the dist.

 

I also have a 455 with a pad stamp
that begins with 30M, complete with E heads
from a 70 Cutlass. It would need a rebuild as well.

 

I have a replacement block with no vin stamping on it. Im in colorado. 720-275-3124
