Re: replacement blocks
Never seen a CE block with a VIN, or an assembly code on the pad. What the block be it a bare blck, short block long block engine was documented by the CE number. Very rarely would GM replace a complete motor. You might get a bare block (CE code) a short or fitted Block (just a block piston and rods) (CE9A code - where 9 is the year), or a long block (CE9B code) and have to use your old heads intake etc. GM wasn't giving away complete engines if you blew yours up, you got the minimum pieces needed to get you out the door.
What's the difference between a 350 LT1 block, and any other 350 that would give you a CTB code on a bare CE block. A 3970010 block (I assume thats the casting number) is just a block, could be 2 bolt or 4 bolt. The CTB code was an assembly code for a complete motor, you can't buy a block stamped with CTB unless it came from an assembled LT1. So if you have a CTB block with a CE number on it it's either all that's left of a complete CE motor, or its a restamp.
