Decoding/Numbers / Re: 1969 Z28 Flywheel

Thank you.

Any Idea what I have? I came across a few threads stating that these are identical in every way and asking weather or not they could have been used on a Z from the factory. Is the 3791021 the only possible option?

Decoding/Numbers / 1969 Z28 Flywheel

« on: March 08, 2016, 05:16:32 PM »

Hi All,

I am in the process or refreshing my motor and I have a couple parts that don't look right. 1st the balancer is wrong (not 7708), it's 8" tall but 1 3/4" wide so it's rubbing the sway bar. 2nd is the flywheel, Part number casting is 3973455 N  then J53 is also cast and finally GM2. My car is a January 1969 car but I can't seem to find any details on the right flywheel.

Anyone familiar with what the 69 flywheel should be and if mine is not right what it could be?

In my opinion, it's a restamp. I see several things wrong with it and I won't say if I don't feel confident.
If I didn't have stampings to compare it to, I'd have thought it was an original - it looks good.

Trans was listed as P9T17A, axle BU1220G.

How are you determining the trans and axle?

Hey All,

Ah yes I remember memorex, I am new to this game so thought it was some specific way to make fake stamps 

Well I tried to upload photos but it keeps failing

Heads: Correct casting (3927186) and dated L188 which I believe is Dec 18 1968
Read End:12 Bolt Posi 4:10 gears dated L178 or Dec 17 1968
Transmission: M21 casting number 3925660 not sure where the date is but the vin is there
Exhaust Doubler plate is present and if I read correctly this is only on Z's, SS's & COPO's

Hey Kurt,

Thanks for the feedback, this is disappointing for sure. I am new to this subject so forgive me for asking but are you 100% certain? Could the picture be deceiving? The PO has two independent appraisals that state this car is real... They could be full of it, just trying to cover my bases here. Also what is memorex, is that a method of restamping? I did a search but only came up with threads like "Is it real or memorex"

So now assuming you are correct how can I even tell what this motor is? It drives like a real 302 but I would hate to push it to 7K RPM and blow it because it's not a DZ... Is there any way to tell without disassembling it? My hope is that the VIN and Assembly stamp are fake and that this is a real DZ motor that was just restamped to fit this car.

Based on the condition of the car and the options I still think I got a great deal I just want to be sure what it is that I actually have.

thanks

The application stamp appears much closer to the head than original stamps that I've seen.   Whether that proximity was possible with the gang stamp holder they used... I'm unsure.  Maybe Kurt or JohnZ can say more certainly whether it's possible to be that close to the head, or not... and they likely have original stampings in that time period or with those characters to say whether they are consistent with original stamps or not.

Regardless of whether the engine is a 'real' one or not, and ignoring the bad date on the carburetor and incorrect master cylinder, you've already bought the car!   and you purchased it to enjoy/drive..  so do it... and if you are interesting in getting into the real details of 'originality', then do so..  but be aware that the more you find out is 'wrong' about your car, it might detract from your enjoyment!  I'd say just drive it and enjoy it... but don't misrepresent it.   As a lot of people say today.. 'IT IS WHAT IT IS!"..

I think the picture is a little deceiving due to the angle that I had to take it at... Looking on the car the stamp is pretty centered on the pad between the edge and the head. I hear you about digging to far, i want a real Z and if this one turns out to be a clone that will be a shame. Regardless it looks and drives like a Z so I am still very happy and I have no intention of restoring it to the point where I don't want to drive it so I will just enjoy it the way it is :-)

I appreciate the input from you guys and would still like some more opinions on the validity of the stamp, at this point it's the one thing that could validate this car as real or clone.

Hey Guys,

Thanks for the input so far. I am very aware of the salvage title, I posted that pic... I have inspected the vehicle very thoroughly and and satisfied that it was built correctly. There was an accident that the insurance company deemed beyond the value of the vehicle so it was totaled. I managed track down the insurance claim and the car was rear ended in 2012 after an expensive restoration. The owner provided receipts to the insurance who decided to total it and pay out the policy. From what I understand the damage was fairly minor but the PO was being unreasonable about the repairs. Anyway, I am cool with the salvage title, I am taking the car to OK where it will be branded rebuilt plus I bought it to keep and drive...

OK now on to the question I posted, The insurance paid out on this car as if it were a true matching numbers Z28, I posted the numbers and pics of the motor in this thread and what I am looking for is opinions on the Engine Pad Stamp, if it's real then I am certain the car is as well.

There are 2 things missing that make this car not 100% both of which I could see having been replaced over a 45 year span...
Carb is correct but a replacement
Master Cylinder is incorrect but the brake booster is right

Decoding/Numbers / Early 69 Z28, Is it real?

« on: February 18, 2015, 12:12:50 AM »

Hi All,

I just bought a 1969 "Z28" and although I have inspected all the numbers I am still not 100% sure it's the real deal, I want to believe it is but am skeptical.

VIN: 124379L515559
Engine Pad: V1230DZ
Engine Casting: 3956618
Engine Date: L188
Carb: 3923289-DZ
Trans: VIN & Date Stamps Match
Rear End: Dates Line up

Can anyone tell me if they are familiar with this car?

thanks
