Hoping someone will help me with a SBC decode. Just pulled from my 56 Stepside and these are the only numbers I can find.
Serial Number stamped on passenger side front corner of block.
355809F56A
Casting number at back of block
3970014
I've already traced the casting number to 70-74 350 2 or 4 bolt main.
Any help appreciated.
