CE engines were over the counter or warranty pieces. We have one in our 396 car. COPO engines had a two letter code. In the Chevelle it was MP for the automatic application and MQ for the 4 speed engine.
question regarding 427 serial number
One of the big blocks I have is a 1969 model year 435 horse 427. It is
not an engine with matching dates, but the block is a 4 bolt with:
3955270 casting date I 6 8 ( Nov 6, 1968 )
I found this information 3955270 427 69 335-435HP 4-Bolt
But the serial number is
serial number CCE 952320
I have never been able to find out what vehicle used that code. One of the possibilities, is that it is a COPO engine, or a warranty replacement engine. Can anyone help me identify the engine? The engine has a happy home, but I would like to know what vehicle it came from.
The crank I have is not reground, but is forged,cross drilled, and grooved. I was not
aware that Chev grooved the big block cranks.
Are the closed chamber square port heads of any value to collectors?
Could I get away with running the 12.5:1 pistons with 300cc aluminum heads on the street?
I was going to use the Chevy intake manifold ( casting number 3933163 ),on one of my 454s, is it too valuable to be doing this?
I have looked in a lot of places and have not been able to get any answers.
