283 identification
Hi. I have been trying to identify a couple of 283 blocks. One site said that one of my 283's is from a 1958 Corvette and another site said it is from an Impala. Would anyone be able to decode my numbers or direct me to a good site that is 100% correct? My numbers are below:
Block 1:
Casting number at rear of block: GM 3756519
Stamped engine code at front of block: FI08DB
Block 2:
Casting number at rear of block: GM 3896944
Stamped engine code at front of block: V050IDA
I also have cylinder heads (power pack). I don't know if any of these would match the blocks, though. Any help here also would help me out a lot:
One set of heads has 3884520
One set has 3795896
And the one spare has 3774692
Thank you again and have a great day!

The 519 block was used from the middle of 58 until late 1961.
Hope that helps a little

The key to the Impala block is the casting date. If the year is "8" and not "58" then it is the same configuration as the Corvette #519 motor. Assuming that you knew the assembly code on the pad would contain a suffix that might not work for the car you were looking to put it into anyway, you would be no worse off than if the engine had a Corvette suffix. Your code does indicate a Flint block.
It could be argued that this type block, (#519 with single-digit year) from a year with no VIN derivative, would be a simple pad restamp of the assembly code (prefix/assy date/suffix) of being any Corvette motor from 1958 you want it to be.
Hypothetically speaking, of course.
Point is, it may not be a Corvette block, but to some restorers who might have to restamp the pad to get what they want anyway, that block could possibly be worth as much as a Corvette block.
