Hey guys I was wondering if anybody could shed some light on this block I just bought... the only info I can find is on the 6618 nothing for a 0618. Thanks so much
-
It's either 3958618 which is a 1968 - 1976 350 block used on full size cars, or 3956618 which was a 1969 only block. What's the casting date?

What's the casting date on the block?

What's stamped on the engine pad?

Thanks for the quick replies guys. I'm just at work right now, I'll post up the other numbers in the morning when I get home. 👍🏼👍🏼

Is this what we need??

192092140. K05 14F3

Here is what I have where the build date is supposed to be
-
I'm from canada so I'm assuming K05 14. Means it was made in St Catherine's on May 14 1969?

Semi Correct. St Catherine was called McKinnon Industries back in the 1960's, so the block was cast and assembled there. 192092140 is the partial VIN and indicates it was installed in a full size car assembled at the St Therese plant. However, can you check the F3 suffix code again? That doesn't look right. Probably FB (as in Boy)? This would be the correct code for a 1969 327/235 with a Powerglide installed in a full size car.

Thanks so much Ed. McKinnon makes perfect sense, which is probably why they have that raised M stamped onto the block. Well it's in great shape, still has the standard bore. It's only a 2 bolt main but if I can build her to 350hp ill be more then happy. Thanks so much for your quick response. Is there anything else I should check?

Wait so is the K for Kansas City? Lol I'm confused

Just recheck the suffix code again (only for MY curiosity!)

No, the "K" in the suffix code indicates the plant that assembled the engine (McKinnon Industries in this case). F would be Flint, T would be Tonawanda and K is McKinnon.
If the K was in the partial VIN, then yes, it would indicate Kansas City. The partial VIN on your block is 192092140, and the 2 is for the St Therese plant.

It definately looks like a 3.... so are we thinking this is a 350 or 327?
-
Sure does! I'll have to check with Warren and see if he has any info on a 1969 F3 suffix code, but I would still expect it to be a 327. However, since it's just a bare block, you can make it a 327, 350 or 302! They all used the same 4" bore.

Outstanding, thank you so much man. I really appreciate it! 👌👌

Hey Ed, I think I found some useful information here....

Hey Ed, it's actually a short block. Complete on the inside. Crank, Rods, pistons etc... if it's a 327 should I keep and use the internals or source Something else out?! I found some useful information here.

Well then, there you go!
327's are GREAT engines! Way unappreciated in my opinion. I've had several 55-57 Chevy's and a few other cars with 327's and they ran very strong. If the internals are good, I'd stay with the 327, but that's just me.

Hmmmm id definately love to keep the 327 aswell, but I measured the stroke and it's slightly more then 3.5" so now I'm not sure what I've got again. Lol. I guess I'll pull the pan off when I get some time and see. I have to strip it down to send off to the machine shop anyways. The cylinders are inaccurate but there's a small ridge at the top of each cylinder so I'm hoping I can go .30 over and it will be enough.

An explanation of the 'M' coded block, from CRG's drivetrain decode info:
"M"-Coded Blocks
There is one exception to the normal block casting date convention that has been observed: some blocks have been seen with "M" cast codes. Research by the Saginaw Metal Casting Operations of GM Powertrain Division has found that these "M" codes are not date codes, but actually a foundry code used to indentify parts that were made to evaluate a casting process change. After evaluating the parts, the blocks would either be destroyed or released into production. There is no way to determine the date an "M"-coded block was poured.

Yes, check the casting number on the crankshaft. Or post a picture of the back end of the crankshaft and we can probably tell you what it is based on the shape.
