I’m picking up my first 442 tomorrow and was wondering how to tell the HP of the 455 it has.
Sellers said they replaced the original engine 12 years ago with a rebuilt 455.
is there anyway to identify the engine?
You'll be able to identify the year of the engine block from the serial number, and cylinder block used from the cast numbers above beside the oil pressure sensor. You might get some idea about whats inside the engine that actually makes the horsepower if : 1. you have the rebuild parts list, 2. Valve size, 3. Pistons used, 4. Camshaft, 5. Carburetor number.
The sellers can tell you anything. Is this coming from a dealer ?
Sounds like you should have done your research before buying it

You could have stopped and left out the denigrating statement. Seriously? He only asked for assistance on determining hp displacement...I don't believe he expected to be brow beaten.

Thanks for the information.
It didn't make a difference if I buy the car or not, I knew that its not a numbers matching car and that it has a 455.

Your question wasn't about a numbers matching car. Your question was 1. "how to tell the HP of the 455 it has". You also stated the Sellers replaced the original engine with a rebuilt 455. Unless you can answer the 5 points I mentioned. you have no idea what the approximate horsepower is. If it doesn't matter what it is, why ask ? What is it that you really want to know ?

I will see if the original owner has any more information on the rebuilt engine today when I meet them to pick up the car. They have the receipts so maybe that will shed some light as to what went into the engine. Or maybe I can contact the shop that did the work. They said it also got a new carb during this time.
When you said you should have checked before you bought it and after reading the other reply I thought you were saying that in a degrading way, I'm sorry for taking it that way. That's one of the problems with forums, you cannot always come across the way you intend too.
I said it didn't matter because no matter what 455 it had I knew it wasn't original and was going to buy it anyway..
I do appreciate you taking the time to answer my question and know I know what it will take to find out the info I was searching for.
thanks again
Ok we got the car home and here is what I found.
The casting number is 296021 Fa
There is a J on the drivers side cylinder head.
The block is stamped 33M388340 on the driver side.
Carb is an Edelbrock with the numbers 1406 7242 stamped on the lower base plate. Does that tell what model carb it is or the CFM?
I found the paperwork on the engine. It came from Marshall engines in Atlanta shipped to Carquest in Fairhope, AL where Deans automotive received and installed it for the OO.
I'm going to try and call and see if they have any more info on the internal parts used in the build of the engine.
Does any of this shed any light as to the year model and HP of this engine?
Thanks in advance!

It's a 1973 block and likely 1973 heads (J heads were used on 455 engines from 1973-1976). Since the engine has been rebuilt and you don't have any information on the camshaft, pistons, head work, machining, etc, there is no way to even guess at how much power it makes.
