Hi, I posted info here a few months back about a 427 that I found.
I ended buying the motor and bringing it home.
Checked numbers today and intake is 3933163 Gm aluminum with the snowflake. Aluminum heads are 3946074,also have the snowflake. Water pump also aluminum 3975928 then has a 5421 stamped under the casting. Also has the clutch and aluminum flywheel, couldn't find the number for it.
Engine pad has CE363909. Previous owner tells me it was a crate motor and never installed in a vehicle. Was in race car for couple years in the 70's.
I tried some searches and found some info, but looking for the experts to chime in. Thanks

sounds like all good stuff , that you should get rid off right away ! Just give me an address. Lol.
The CE means counter engine , but you didnt list the block casting and that would tell you closer to what engine displacement it is ?
Great find , very cool.

Guy I got it from is insisting its a 427 crate engine that they bought new in 1973. I told him about the 454 casting and all he could say was that from the day they bought it new, they thought it was a 427, they had 4 of them, I bought the last one. I don't think he was trying to hide anything, I have got alot of things from him and everything has always been just as described.

Check out the cast dates of the heads and intake to see how close they line up. These items could be off the original motor and moved to the warranty short block in 1973 giving you a clue to the date and internals of the warranty block you have. The current block in production for the 1973 model year would have been used to duplicate the build characteristics of the damaged component. Look for an assembly date code stamped at the flat surface under the starter.

The block might be a 454 but the engine could be 427 cu in anyway, it depends on the crank in it. It could have been a 427 from the begining and has got the block changed after a few years (CE# is a hint here).


Great find :thumbsup:

Thanks for all the info, I don't have the numbers on the crank. Only thing ever changed on the engine was the camshaft, still have the original cam in the GM tube. Has a set of Crane roller rockers in it as well. Supposedly only has about 500 miles on the motor, it only ever went in circles. What is an engine like this worth with all the good parts on it. I paid $1500 for it.Pretty sure I got a good deal.

Easy to tell a 454 from 427. 427 was internally ballanced.454 was externally balanced, so the flywheel and balancer both have counterweights cast in. The 512 block used in 69 427 was also used in 70 454.
