See there? I go and update the links and nobody wants to use them...(pout)!

Check this one out, Joe. It explains the casting and part numbers pretty clearly:

So its not out of a Trooper car I take it. There is no way to know what heads are without taking them off?

 

Cop cars didn't use anything special. They were built with standard production engines and they called these "Special Service Vehicles". (Do a web search on that subject...interesting stuff.) I had a former CHP Mustang, it had the standard production 5.0 and T-5 tranny.

You can tell what the heads are when they're still on the engine by pulling the manifold and looking under the edge of the head where the pushrods go through with a small mirror. That's where the casting number is. Other than that, it's not easy to tell. Some disassembly required...Ford didn't plan ahead very well on that one.

 

That cool the lowers are off on both my engines.

Thanks, Joe

 

Hey, TigerDan, do you have any links that decipher Mercury Marine Blocks? I have a Mercury Marine Block with D2OE-AB as the casting #. It has E5AE-CA heads on it, and what are the differences between 302's and 351's?
I'll check tonight to see if it's a Mexican block. It has an aluminum color like coating on it along with some red.

Thanks
Dustin

 

Ford casting numbers are Ford casting numbers...whether used in automotive or marine applications. (As far as I know.)

Look back at the second post in this thread, I think Desert Dave already decoded those casting numbers for you.

 

Eh, they aren't right, we got to talking and we havne't been able to find anything on the D2OE-AB block. I'm going to take the oil pan off and see what the crank says.

guess MerCruiser does give out a lil info...lol
I at least have 225 hp, but i have been told it was making at least 300hp and it was a screamer. It was in a F-150 mud competition truck and almost took 1st in a 38 inch tire class. I was wondering if i should put a 2 inch aluminum carb spacer on?

Thanks for the help
Dustin
