whats it worth?????????

[jkh04200]

Anybody have an idea what a 302 short block would be worth. I was bought from chvrolet about 30 yrs ago and cant have over 1500 miles on

[Sleek-Jet]

You mean the kind they used to chain to the frames of the original Z28's???
I'm sure there are some Camero guys that would give a premium for that. Might be a good idea to check out some chevy forums. See how much intrest you get.

[jkh04200]

Yes that's the one. A good friend of mine bought it from Chevrolet and put it in his 34 Chevy coupe. He was only 17 and decided to sell the car. He had found a Chevelle he wanted. His Dad bought the 34 from him. Where it sat in the garage for 30 yrs. It was started and driven 3-4 times a year. Now that my friends kids are done with college and on there own he wanted to get him another "hot-rod". His Dad gave him the 34 back for his 47th birthday.

I still have a 302 for sale, The best of everything. It is apart for the buyers inspection. It has less than 30 laps. I have the dyno sheets that show 450 hp corrected. The block is an origonal Z28. I am asking 5K carb to pan. :idea:

Can you get a casting # off the block? May be interested... :cool:

[Earl]

The number is 3970010. It has a L.A. Kriptonite billet Crank, 6 in Carillo rods, Isky roller rockers and girdles, Cosworth pistons, huge Iron heads and a Victor jr. port matched. You have a choice of carbs. There is an extra top end cam new in the box. It comes dry sumped, Avaid pump and pan. If you want a stock pan and pump that's easy enough. The crank and Clevite bearings ars beautifil. every thing is balanced. If you are in the market, P M me.

[BrendellaJet]

Earl, can you give me the code of the machined pad underneath the passenger side head?

[HOSS]

No he can`t its probably been decked. I call bs on this.

[Moneypitt]

From Mortec:
3970010....302.....69....4...Z-28 Camaro
3970010....327.....69....2...Trucks and industrial
3970010....350...69-80...2 or 4

[Earl]

Gee hoss, your right, it is decked. If you want to call John Wolf the engine builder full of sh-t that's fine. Buy the way, how many land speed records do you have, or how many APGA recorde do you have! Ho the fu-k are you???!?

[Earl]

correction--- WHO---I would like to know your credits!

[396_WAYS_TO_SPIT]

I was going to post but I think I will stay out of this;)
Oh and by the way, mortec has a few numbers that are WRONG! Just to let a few people know;)

A 302 has the same block as a 327.... and they did only make them for the Z28 from the factory for one year.
R A R E .....
Not very many of them survived. Most Z28's ran around with a 350 because the people had grenaded the 302's.

[jkh04200]

Brendella,
I'll get the # for you. He's already asleep, I'm sure. He told me the reason he bought it ws because it made the most HP of the SB engines GM offered as crate motors. I believe they claimed 340hp. He laughs now and says " hell I was young did'nt know anything".

Huh??? The 67,68,69 Z28's ran 302's. The Z28 became a 350 in 1970.

1967 302 used the same block as the 327 and a 283 small journal crankshaft. Engine had 2 bolt main bearing caps from the factory Casting numbers were either 3892657 or 3903352
1968 302 used the same block as a 327 and 350 and a shorter stroke large journal crankshaft. Engine had 2 bolt main bearing caps in 1968 Casting Number should be 3914678
1969 302 used the same block as a 327 and 350 and a shorter stroke large journal crankshaft. Engine had 4 bolt main bearing caps in 1969 Casting Number should be 3932386
probly more than you wanted or needed to know.......... :idea: :idea:

Depends what it is, casting numbers and date codes!!!
It will be worth the most to someone restoring an original Z28, if it's the right casting numbers.

Only if the block hasn't been decked and the numbers are still on the block by the head!..

Earl,
How about tending to your list.
If you aren't the same 302 as the thread poster, post your own thread and don't hijack someone else's. The nerve of some people's kids.
:rolleyes: :rolleyes:
Your 302 sounds like cubic inches and nothing else.
The thread starter sounds like he has an original, unmodified "real" 302.
Give some space,
Brian

[BrendellaJet]

looking for a block that has not had the serial #s decked off. Looking for a DZ block.
Earl, if your engine builder is all "that" he probably would not have ground them off, hence not the block Im looking for. Thanks anyways.

[Floored]

need a 3932472 original unmolested intake with factory finish?

Are you talking about the two-four barrel crossram? You have to be.
Post some pictures of that badboy.

Pretty sure that is a 4 barrel intake.

[wsuwrhr]

Pretty sure that is a 4 barrel intake.
Oh ok
thought the DZ had a crossram.
Brian

[jkh04200]

Sorry for the delay, I'll post the #'s tomorrow. Its definatley a 69 and has the 4 bolt main. Makes sense, this thing does have a 4" bore but a real short stroke cant remeber off the top of m,y jead what it was. Something like 3.25"

[Moneypitt]

That works out to a 327 ci in. ...................4.0 x 3.0 = 302 cu in....MP

[jkh04200]

Moneypitt,
Your right it is a 4 x 3. I couldn't remember exactly what the stroke was. It was several weeks ago he told me the stroke.

[godfather]

I'm makin' popcorn ... Who wants some?
i will take some LOL :220v:

[HOSS]

Popcorn gives me gas. :yuk:

[Floored]

DZ and MO were the Z28 302's and were available with the single four and the optional crossram intakes. Headers came in the trunk and the chambered exhaust was cool sounding also.

[HOSS]

Gee hoss, your right, it is decked. If you want to call John Wolf the engine builder full of sh-t that's fine. Buy the way, how many land speed records do you have, or how many APGA recorde do you have! Ho the fu-k are you???!?
Who the hell is this cat? rollin with tha homies! :cool:

[jkh04200]

Okay heres the numbers.
On the pad in front of the passengers side head
CE5N2 9 6
On the back of the bolck
3970010
If I read Norsemans thread correct, the main caps are as follows
#1 G951
GM890
#2 2482
GM17NF
#3 2482
GM18NF
#4 2482
GM20NF
#5 cant tell due to the oil pump
Sorry it took so long.
Also, may I add, Can't we all play nice. Earl & Hoss y'all are gonna be put in time out if your don't behave :D

[Moneypitt]

There should/could be another series of numbers on the block pad. Those numbers aren't long enough, and I think the letter designations follow the engine ID number, the last 4 digits of that number match the VIN of the vehicle it was installed in, ie: matching number, original car/engine.....(The numbers you've posted look like the same type as the numbers you see on a BBC right above the T/C mounting surface, on a horizonal pad). Those are not the engine ID numbers..........MP

[jkh04200]

I'll ask him to look for some more #'s. Remember this motor was bought from chevrolet. So it was never assigned a VIN #

I'll put that in the trivia file... :D
My mistake on them only being made for one year. That's what a couple "Camaro" guys have told me. Wasn't the 302 built to satisfy a santioning body?? 5.0 L was the largest displacemant allowed??

[Floored]

Yes, 302 was for the trans am series. 327 block and 283 crank seemed to fit well at the time. factory rated at 290 hp they were a dog until you put some gears in the rear.

Big bore-short stroke. Lazy on the bottom.
I remember reading a book a long time ago that the 302 was a special motor, that the 327 block 283 crank worked out as far as cubic inches went, but it really wasn't the same thing.

"CE" suffix means factory replacement block.
I had a 67 z28 with the "mo" block.Just sold it back to the original owners son.Had the original build sheet for it tooooooo.

[CircleJerk]

Here is another thing to do. If you find a 67 350 block its designation code is MU,,,,then just close the top for a MO! Veola, a 1967 numbers match. Now the over the counter blocks did not have these since the plant did not know what car model they went into. However, a date of manufacture is near the bellhousing flange where the cast number is, usually on the other side. This may or may not help, but it is easy to check if someone says its a number matching block sold over the counter. I had two 1967 Z28s at one time and learned quite a lot, wish I had them back! One was a black Ralley Sport with 31000 miles! Tachometers also had a higher red line of 6500rpm but it would pull, in gear, to 7200 and that was around 121mph!

The numbers won't match if it's sold over the counter because in 67 and 68 the last 6 numbers of the vin are stamped into the block pad and the otc won't have that.
I think your idea is pretty sorry anyway.Anybody that knows their shit will see it's forged.

[jkh04200]

I found a few more #'s
Under the timing chain cover, passengers side
020
509
010
Drivers side
512
534
G14
Behing the flywheel, passengers side
509
H17
010
020
It has a forged crank, pink rods, TRW pistons #3927172
I doubt these #'s mean anything. But, thats all there is.
