302 Boss help

[Ash]

Can anyone please help me shed some light on what it is I actually have here?
We were told when we brought this about 8 years ago, that it was a 289 with a 302 top end. We brought it for an XP project but my Dad got sick at the time and he sold the car. I've looked at it a few times over the years but it's been under covers in the corner of his shed the whole time. I brought it home today.
I knew it was a clevor set-up and that it had BOSS stamped into the intake. Today was the first time I've looked at the numbers and realised it was a 69 make. But can anyone else help with the rest of the casting numbers?

I have no idea why either there is a separate set of numbers engraved into it?







I'm pretty certain it is a 289 bottom end as the crank has 3 bolts on the front of the crank, that correct?

I'm not sure what heads are on it but should have taken some closer photos, I can do that tomorrow.

Interesting Ash.

Looks like a Clevor, but I would imagine its a 302, no ?

In 69 they replaced the 289 with the 302 didnt they ?

I thought a 289 and a 302 very pretty much identical from the outside ?

I'm no expert tho ...

Is there an engine number ? should be one in 69.

Cheers,
Frank.

This link should help Ash - it is a 69 - 70 302 Intake Manifold.

Also I have had a look at my Don Farr 1st edition Boss 302 book which has all the casting numbers listed and C9ZE-9424-D is listed as a 1970 intake manifold.

I didn't even think of looking at the block details, Frank, I should have. But since we were told it was a 289 bottom end, I just didn't even consider it. Stupid me. I'll get some more details on that too.

I thought the 302 top end component bolted straight onto a 289 block as well?

I don't know the originality of the engine. The guy we brought it from had it in an XY that was just redone but then smashed. We were told it was fully balanced and blue printed but we haven't put a spanner to it to verify any of that.

That's great info mwizz, thanks!

So would that verify this is as an original 69/70 intake, not something produced after?

Any ideas why the specific 1970, C9ZE-9424-D Part No. would be engraved in?

Was it also common for the "BOSS" to be stamped in as well?

What are the markers I should be looking for on the heads if they too are Boss components?

I found this page, if anything I should find it against the details here I would guess.

Just found one on Ebay US

http://www.ebay.com/itm/69-70-BOSS-302-MUSTANG-COUGAR-ALUMINUM-INTAKE-VINTAGE-FORD-SUPER-CLEAN-/300538457671?pt=Motors_Car_Truck_Parts_Accessories&hash=item45f97cee47&vxp=mtr

And another with the following details about markings

http://www.ebay.com/itm/1969-1970-Mustang-Boss-302-Complete-OEM-Aluminum-intake-manifold-C9ZE-9424E-/190656809090?pt=Vintage_Car_Truck_Parts_Accessories&hash=item2c64080882&vxp=mtr

This looks to be a rare 1969 intake since the date is 4/24/69.  Buddy Bar casting on the bottom.   That definitively for a 1969 car.

I'm no expert but it does appear to be a genuine casting number.

There is a difference between part no. and casting number. The part no. according to the Farr Book (as well as in that link) is C9ZZ-9424-C and applies to both the 69 & 70.

The casting no. is listed in the book for the 70 as C9ZE-9424-D. I am thinking that someone may have inscribed the 70 casting no. in the manifold maybe because it is the same part as for the 69? (so they wanted both casting numbers to appear on it) but that is a complete guess.

Not sure about the question about the Boss being stamped in but Sean from Bosskraft should be able to clarify.

[Ash]

Cool, awesome stuff. A nice little goody to have tucked away :smile02:

I'll grab some more details of the other parts and see if I possibly have some more Boss equipment on here and contact Bosskraft from there.

Cheers:thumb:

[mwizz]

No probs Ash. The original Don Farr book which I have does have part numbers and 1970 casting numbers listed so I can look them up for you if you find any more.

[Ash]

Great, thank you! I'm off to a car show in the morning, YAY! :thumb:and will be back hopefully in time to mow the lawn, BOO :banghead: I'll try and take a rocker cover off and have a look before the sun goes down.

[Frank70]

Hey Ash.

great bit of kit you got yourself.

Yeah, the 302 topend would bolt to a 289. So this is not a genuine Boss, but a homebuilt one you think is based on a 289 ?

we really need BossKraft.

Cheers,
Frank.

[Ash]

That's the feeling I have, Frank. Could be Boss 302 from block deck up. We know now that the intake is genuine but will find out more about the heads.

[Frank70]

Cool Ash.

What do you plan to put it in ?

Cheers,
Frank.

[Ash]

No idea at the moment. Haven't had any plans for it since we brought it to put in my Dad's XP that he ended up selling. It is the perfect motor for my 66 but I plan on leaving that a 6cyl. I love that car the way it is.
Dad hinted yesterday at putting it in an XY ute but I know he doesn't want a project car. If I were to get another Mustang, I wouldn't be concerned about one with good mechanicals as this would be the one to go in. I just know I wont be getting rid of it, it can stay in the shed until a body comes along. Not just because it has some Boss bits on it, but because the XP Dad had was a car I brought him for his 50th, he wasn't well enough to see the project out so I'd still like to see him enjoy it in something one day.

[Ash]

Popped the covers off this arvo and woo hoo, roller rockers!



Looked all over the heads though and I can't see any casting numbers. All I can find is a 3 in the bottom right corner



K3 here



A "P" punched in here and you can also see the "2" in between the valves



Looking back over the link mwizz provided, I do not think they are anything special, certain they are not Boss heads, even the ports don't look like the Boss ports. But what are they?



For the block, I couldn't find anything either, nothing anywhere.



And I thought the engine number was typically at the back of Windsors? Sorry, not that familiar with them but I thought that was the case. This one is stamped on the front below the R/H head next to the water pump



Here's the front of the crank



And the numbers on the pulley



It's looking like a bitser to me.

[mwizz]

Couldn't find that pulley number in the Boss book Ash but found this:

http://mustangtek.com/pulley/C5AE-6312-C.html

Appears to be a 289 crank pulley

[Ash]

Looking like it is just a stock 289 bottom end.

I looked around for some examples and it looks like the exhaust ports are just typical 2V ports. Which makes me wonder what they have done on the inlet side.

[jademustang]

Like Frank70 says looks like a clevor.
engine number if stamped will be on a machined pad at the top rear of the block. if the block has been faced then it may have been machined off, most machiners will restamp there after. could have been engraved lightly in a non machined area so that the block did not loose it's number.
block id on a horizontal surface above sump line near rear of block like in first photo below.

block casting and date code

[Ash]

Ah, thanks jademustang, I can see how I missed that casting code. I'll have to lift it up off the tyre to have a look.

The engine number though is stamped on the front just under the R/H head and beside the water pump. Like you said, they are stamped on the back usually which is what I thought too and why I found it odd that it was on the front.

[staddy]

Ash , The heads are 302 cleveland small chamber 2v Australian heads , cheers Staddy

[Ash]

Awesome, thanks Staddy. I had a feeling that's what they were looking like being, thanks for confirming that.
