We have a Engine with Block #3956618, Heads #3927186. It appears this engine has not been modified. The Winters intake is not present, it has an Edlebrock Aluminum Intake. Manufacture date per research is 2/69.
There are no numbers stamped on the front block pad. We beleive this is an 1969 302 double hump 290 horse engine. Are we correct, I REALLY need some feedback, Thanks

Welcome, Mitch.
Since there is no engine code, it's just a engine.
However, a stock DZ 302 has pop-up pistons and measure the bore and stroke of the short block determining the CID.

Maybe others here can help on how to identify.

Without access to a traceable Suffix or already recorded VIN it would be impossible to 'confirm' it's original assembly status or use ...

Look for possible VIN stamped on side of block and post it for comment.

Without a pad stamp it's not a DZ motor. Check behind alt and down at the pad near the oil filter. No pad stamp means it's not a DZ, at least if it's original as claimed. They made 327's and 350's with that same block and head configuration. They were just not the 2.02 heads, they were the 1.95's.

There are literally 20+ posts with pictures of engine stamps in this section of forum for the last few months if you want to see what it should look like and where.

http://www.camaros.net/forums/showthread.php?t=178858 about halfway down the page is a decent shot of the stamp near the filter. ( on a 68 )

Yep - what they all said above X2. No way to tell what it was originally without the application stamp, and using the partial VIN is a long shot. Even if you stripped the engine down and found the internals match the DZ specs doesn't confirm that's what it started out as (it could have been rebuilt to 302 specs from a 327 or 350).
Out of curiosity, what is the casting date of the 186 heads?

If it has a VIN stamp of N613111 it is my long lost block.......

Please post a close up clear picture of the pad.

Could be ( )
Maybe it ran-away to Nashville to be a Country Music star and when it washed out it rode the "Chattanooga Choo-Choo" to Benton
Hey - it could happen

We are going to get it up on a stand and give a good cleaning up. The Block number is 3956618. The Heads are
3927186 double hump heads. We came up with Man date of 2/69 from the casting. The pad is blank, we are going for the number over the oil filter. It has the original point distributor, the Winters Intake is gone, replaced by an Edelbrock. When My brother in law traded for it years ago it was running in a mid 70's chev pickup, really a high winder. It has standard gm vavle covers, some idiot probably took the ribbed alum for their own motor. I have a special intrest because I had a new 72 Vette 350 with ribbed valve covers, and a new 73 Z28 I ordered, I don't remember the valve covers on the Z, it was a 350. I raced a buddy who is the Sheriff of the county I grew up in now. He had a brand new 73 Trans Am Big Block. We went to the local 1/4 mile straight and I absolutely ran off and left him. He had tears in his eyes when we pulled over..I don't care what ratings they gave the engines in their new fuzzy math, My 73 Z would haul butt. I was 17 but I remember having it at MPH and it registered 130.

what are the distubutor numbers

[RSR]

Do you have a crank ?If so what can you tell us about it? A 69 DZ balancer is different and the block should have bolts in the caps for a windage tray.If it has been rebuilt and decked you only got a good block now.If it hasn't been check the bearings..they are dated.

[mthurmerm]

We have not took it apart, We are putting it on an engine stand today, clean it up and really check the numbers/find. What is the diameter of the correct harmonic balancer, 5 1/4 or something like that ? I have read so much it is running together. I did get the number off the head, under the valve cover and now don't remember which it was. I thought at the time it was correct for a 2.02/1.9,,I will get all this organized today and repost with some pics this evening. By the way boys remember to call your Moms today or put some flowers on her grave, I will have to do the flowers, My mom has been gone for 12 years..Mitch

You don't have to take it apart to see if the crank is 302. Take a pic of the flange of the crank that the flywheel bolts to. A 302 will have a notch in it that looks like a slice of pie.

Well, All I need some help. One thing for sure, it is not a Z-28, Maybe a jacked up 327. Help me identify if y'all can. I am going to list numbers by item.
Block: 3956618 Man Date 02/69
On Back of Block: 843 Further to the right on back: 632 over 618
Over Oil Filter: 871 over 386
to the right: 108N
Heads: 3927186 to right: 11-9 also: GM38
Distributor: 1112844
Crank: 3911001 Has 2 Bolt Mains
Harmonic Balancer approx 7" Diameter
What Info I researched, Crank 3911001 was in 69-69 327
Heads were used on Hi-po engines in 69 Vette 350 300-375 HP
Distributor came from a 1974 350 2bbl Pass Veh
Pics don't do alot of good. We have determined that probably someone took a 69 350 block and dropped a 327 crank in it with the Hi-Po Heads. The guy my brother in law got it from said it was a high RPM engine. Anythoughts, I need some Help,,Thanks Mitch
