I have had my Bronco for 2 years now. It is a '73 w/ 302, 3 on the floor, and a 3 inch Susp. Lift.

About 4 months ago my stock carb sprung a leak. I replaced it along with my intake Manifold, with and Edelbrock Performer Intake and an Edelbrock 600cfm Carb. The difference in power was significant. Anyway on my way down the road, My oil pump went out the oil pressure guage did not change so I was unaware that something had happened until I threw a rod .

Now that the History is over I will get on with the current story.

I happened upon a 351W that had been used to power a motor home. The engine seems to be in good condition. So I purchased it. After getting it home. I decided that since the engine was not installed. I would replace the Timing chain, Gaskets and Freeze plugs.

Question 1:

How the heck do you remove a freeze plug?

This may be a silly question but I have tried several methods which have not worked, Mostly because I don't want to damage the Engine. Is there a tool to use?

Question 2:

Is there a way to find out what year the engine was made? Where do I find a serial number or something that will give me a clue.

The only Thing I can Verify myself is that it is a 351W, and it was set up to run on Propane.

I know it is long, Please forgive me.

 

Welcome to FTE Richard

Glad to have you aboard!


Question 1:

How the heck do you remove a freeze plug?

Very simply. Take any punch, big HD screwdriver or whatever, and drive the freeze plug in (**** it sideways) the bore, and then retrieve it with pliers, channel locks, or vise grips. You wont hurt the block as long as you're only hitting the freeze plug.

Question 2:

Is there a way to find out what year the engine was made? Where do I find a serial number or something that will give me a clue.

I've never had much luck with casting numbers, but if you'll look at the underside of the block just above the oil pan rail, there should be some numbers there. put 'em on here and we'll look 'em up for you. Your best bet will be to get a manual on the engine if you're not too sure about what to do.
Other than that we'd have to go on clues, such as ignition system. Is there no emissions sticker on the valve cover? What color paint is on the engine? Blue is usually the seventies, grey-eighties, etc.

Anyone else can help him out here?

I know it is long, Please forgive me.

No problem. Welcome aboard!

For engine ID of a 1973 351 W you should first either look for a metal stamped tag under the coil mounting bracket, dipstick tube or under the water temp sender (used until Feb 1973) or a white sticker on the right valve cover. If you post the numbers off of that You will get the most information. If (like many engines) your lacks this, the year can be told by the casting number on the block. It will consist of something like L#LL-####-L with L standing for letter and # standing for number. The first 4 characters are the prefix. The first letter C would mean its from the 60's. A letter D would mean 70's. The second character is the year in that decade. D3 would mean 73. The next character is the car line the engine was origionally designed for....O for fairline, J for industrial Engine. The 4th character is the division of Ford. E would be for engine. The next 4 numbers are most likely 6010. this is the part number given to all ford engine blocks. Finally the last character is the suffix which tells the change level of the part. There are also numbers like this on the heads. If you post them or the engine casting numbers i will tell you the specs listed for it. Hope this helps some

Thanks for the Info Guys, I apreciate it. I will be tapping those Freeze plugs out this afternoon. I found a Site that ,


Explains Casting Numbers
before I read your Post, Matt.

It explains exactly what you Said.

I found that the engine had no Sticker or Plates with Numbers on them. Although the Engine was painted blue. The casting number

E5AE-C3B

1985 Ford Engine.

That's the First 4 slots in the Number. Through some more searches I found, but I am not entirely sure, That it is actually a 302 and not a 351W as I was told.

Can you help me out with the

C3B

Part of the Casting Number? The Part number I did not see. The exhaust Part number is

E3TE-9431-AA

85 Truck Engine

This part I found is for both the 302 and the 351W.

Which still kinda throws me off. I have found no other Casting numbers. I guess Ill just have to take the Valve Covers off and check the Heads to see if I find any casting numbers on there.

Thanks in advance on any Feed back.

 

I made a mistake. And had the same Message Twice Don't want to overwhelm anyone.

 

My engine is sitting on an engine Stand. and it was upside down to find the Casting number on the block.

When I flipped it back over I found the Casting number on the Intake Manifold. Which I have not found a Match for on the Internet. Can you also Help me with this? Thanks

E3AE-8425-BD

83Ford Engine. What I need to find out is is it a 302 or 351W as it takes Diff Intake.

As I said above the engine that I currently have in my Bronco is a 302. with Brand new Edelbrock Performer intake and Carb.

If it is a 302 I can re-use the intake and basically all the parts on my old Engine. If it is a 351W I will have to Purchase a new Intake Manifold.

Thanks Again.

 

The intake manifold number is a * 9425 * not 8425

The Block has a 6015 Number.
Look for markings like this

I thought I had posted that Earlier.

E5AE-C3B

Am I incorrect in assuming that?

The picture you have looks almost exaclty like what I am reading from. Right behind where the Starter is Mounted.

Is there a way for me to find out whether or not it is a 351W.

At this point I don't think I will ever find out what Vehicle it came out of. I can see by the Adapter on the Carb that it was meant to run on Propane. This gives me an Idea that it may have come from a Motor home. The biggest reason I am curious. Is that I need to find parts for it. So I can finish building it and putting it into my Bronco.

Also I removed the Freeze plugs from the Engine Block. It looks like someone had already done this. It also looks like they Primed and Painted the Freeze Plugs prior to instalation. I guess that is a good thing.


I will take a Pic of what I see and share it with you all.

 

The easiest way is to measure across the intake bolts. The 302 is approximately 7 1/2 inches wide and the 351 W will measure out at about 9 1/4 inches You could pull the valve covers off and see if the heads are cast with a 351 or a 302 stamp but that is not definate because heads can be interchanged. Also it is likely that your block and manifold are from the same year. Block castings arent the best way to tell. The stickers on the valve cover are. One way to tell once you have a valve cover off is to check the length of a pushrod. A 351 has half inch higher deck height so the pushrod is longer. for a 351w it should be somewhere in the 8.2 inch range and a 302 will be much closer to 7 inches long.
Hope this helps some

 

Richard,
The quickest way I know of is look at the front of the engine. Where the timing cover water passages go into the block. If it's a 302, then the heads will be DIRECTLY above those front water passages. If it's a 351 then there will be an inch of block showing before you get to the head.

I know a picture would be better, but I don't have one.
It's hard to explain without one. But that's how I tell.


Good luck,
Chuck

 

I have always used Chuck's way. Unless they are side by side, it can be hard to tell by the intake if you don't have a tape measure.

The oil pan rails are also wider on the Windsor.

e5ae casting is for a 302 block from a car. had to dust off a old book.

 

thanks again for the Help.

Ok So if I am looking at this correctly. I have a 302. Which is fine with me, even though I was told it was a 351W by the person who sold it to me. I will post pics later tonight when I have my laptop back.

At least I will be able to take the parts from my other engine and use them on this one.

 

I am not sure but didnt the heads change in 1983?. Early 302 heads have small water passage openings at each end. The newer ones have large almost square openings. Make sure the replacement intake manifold, will fit early and late model heads.

 

Ok since this is the 4 time I have tried to write this. And for some reason I keep closing my browser window And I never complete the transaction. I will make it short.

It is a 302. The 2bbl Manifold from my old 302 is the same width and length as the 2bbl Manifold of the new Engine. 9 inches.

I will check tomorrow to see if the water passages are the same size.

Spartimouse.

Just to let you know. You are correct in that the E5AE went into an 85 car. it was also used in Trucks as a 302 from 85-90.

Also to let you know. The E5AE was also used to make 351W engines for Trucks from 87-93.

As I promised I have added the Pics to a site I put up just for pictures.

I will add more pics as I go along. I will keep you all posted. And we will see if I can get the new engine to Turn over.

I have now taken the Engine down to the block.

So I can replace:

Intake
Carb
Cam & Lifters
Timing Chain

With:

Edelbrock

Performer Plus Intake (Performer 289 (non-EGR) #2121)
Performer Plus Carb (600 cfm, square-flange, electric choke #1406*)
Performer Plus Cam Kit (Performer RPM Camshaft/Lifters/Lube Package #2122* )
Edelbrock Timing Chain Set #7811

I don't have the money for the Heads other wise I would be getting them now.

Edelbrocks numbers with these Items are:

367 HP
340 Ft/lbs Torque

I think that'll be enough to get me around.


Can't wait to see if it runs. Lol
