Re: CE Engine Stamp Prefix
1 All the numbers that are pertinent to understanding what the block started out as are, the casting number. Which you have only touched on in a vague sense. We need specifics. The casting date is essential as well. You have provided the stamping from the pad. So only two more essential numbers remain.
2 The CE stamping adds to the case for a deduction as it gives a year other than 66-7. That information at this point is good for having a better understanding of what the block is. But the casting numbers are judged before anything on the stamp pad as Page has said.
3 CE and what it means- there are a number of discussions in the archives. John Hinckley explained the CE & CT program, it's duration and how to interpret the stamp. Search John Hinckley CE. The CE program is also covered in an actual Chevrolet document. There is a Chevrolet TSB (Technical Service Bulletin) which was distributed to all Dealers announcing and explained the program to those in the field.
4 I'm sensing from your posts that your under the impression the CE blocks were warranty replacements only. CE engines were a service part. Meaning they were sold through the dealer parts department. Or over the counter as they say. The majority of CE program blocks and engines were sold retail/wholesale rather than warrantied. GM has never been too quick to warranty a fitted block, short block, long block or complete engine under warranty. Most dealers would have required DSM (District Service Manager ) approval first in order to be paid under warranty.
5 You are correct, CE stands for Chevrolet engine. This is explained in John Hinckley's post and the Chevrolet TSB. Some have applied names like Counter Engine and others, they are urban myth or old wives tales. Also part of the program were CT's as in Chevrolet Transmission. OE, PE, BT meaning Oldsmobile Engine, Pontiac Engine, Buick Transmission and so on.
6 What's the difference between a CE block and a service block? The short answer is no difference other than the CE was a program that ran from 69 into the early 70's using a specific identification system built in large batches. CE engines have no identifiers that specify compression, hose power or application. Meaning one has to tear a CE down and measure things to determine what what you have.
7 As a thread will tend to stray from the OP's original question I will wander back to it. The probability is that your CE block will will have a casting number ending in 512. Resulting in a 350 point deduction for the casting number, the casting date and stamp pad. Judges then move on to the heads. There is a thread back in the archives that discusses a warranty block that had supporting documents (work orders) showing it was replaced very early. It may have been of a proximate date to the car. I forget the details. That thread relates to the judging consideration you allude to. Scoll down this page to find related threads or search the archives as suggested.
8 don't forget to give us the casting number and casting date. They are your only hope to minimize block deductions at this point.
