Technical Mystery 327 what is it?

It's a 350 block, from what I can see.

If you provided the casting dates of the heads, block, and intake, and the crank if it's a cast crank, then we could see if the parts match each other. But it sure looks like an engine that's been worked on.

 

Jim i will soon....
did gm make 327's with 4 bolt FOR trucks?
criteria 1968 / 1969
I'm fully capable of looking up numbers, thanks for the offer.

 

Dual tab T-cover.
Restrictor plate for intake/ carb.
No harmonick , just solid piece to hold belt pulley.
Exhaust up, with the down side block-plated off.

 

double roller timing chain?

 

all SBCs came out of Corvettes

 

looks like 350, 302 and 327 shares some casting numbers
there is some web talk about 4 bolt 327s in HD trucks in 68

 

looks like the work of a meticulous engine modifier...probably during the 1970s.

 

Oil Filter adaptor....... Double Roller Timing Chain.........Aluminum Intake valve Retainers.......
Ship it to B/J Auctions ASAP and tell them only 21,500 Documented Miles ....

 

Ag pump or generator? Looks industrial

'65 and '66 Studebakers used Canadian GM engines. The V-8's were all 283s with a two bbl carb. Of course that doesn't mean the engine in question could not have been improved upon. These GM engines were made by McKinnon industries. One of the heads on my engine actually have CANADA embossed on it.

 

Massey-Ferguson put 327s in combines.
Here's some interesting reading about it:

Are you sure it is even a chevy?
The marking on your heads don't match any chart I have seen.

Double row timing gear and chain set, never saw those in passenger cars, only trucks. Medium duty C40 and up.

The block thing gets screwy though. 1968 had some 327's with an 010 casting block, all of those were two bolt mains. THe 350's built with 010 castings could be either two or four bolt mains though. There was supposed to be one 327 cast 3955618 was a 4 bolt, car only, no trucks. Never seen one in the flesh (or iron), just in reference material only. I have seen both 2 and 4 bolt 010's though.

Service replacement blocks, all bets are off. I've seen things that made no sense, seems at times the factory used whatever they had on hand for a block casting but used the correct pistons and camshafts.

That oil filter adapter is not factory. All the SBC adapters from GM were cast material, that includes adapters for engines with oil coolers. That adapter also appears to make the filter mount outside flush with the bottom of the block casting instead of slightly inside the block casting. Also never seen an allen capscrew from the factory either.

1968 car blocks had a spin on oil filter EXCEPT for some early ones that used leftover 1967 engines. The GM parts book used to reference that note.

That carb spacer throws me off, never seen that in any production engine either car, light truck or medium/heavy usage. The exhaust manifold, same thing. It must have been made for a specific non motor vehicle use, like maybe a stationary irrigation pump, ditto for the solid front hub instead of the harmonic balancer.

 

There are parts out there with a GM casting number but cannot be traced or found in the "normal" GM system as they were sold outside of the corporation on a contract basis. Think like Mercury Marine, et al. Only available through their dealers as it was built for their needs and specifications.

 

Wyld
7/16 bolts (5/8th's socket )in that pic , but only on one end...
the other end has normal 3/8 (9/16 socket)

 

arkiehotrods nailed it, this link has a small picture but it shows that type exhaust manifold. Used on Massey-Ferguson 510 combine with 327 for early production, later 510's had 350's.
I wonder if the 3955618 4 bolt 327 block that shovelheadrider mentioned was for the rare '68 327-325 L79?

Seems to have that carb spacer also. For quite some time, there was one of these exhaust manifolds for sale on that auction site, but I can't locate it now. The head marking is really odd, and that 327 has the "performance", boxed valve covers, but a 2 barrel carb?. Casting numbers? I am Butch/56sedandelivery.

 

Ding Ding Ding ....winner winner chicken dinner...
arkiehotrods nailed it ....
I knew it came from a MF my old neighbor guy gave me this engine.
I'm supposed to pick up the other one anytime i show up.

 

You guys ALL did GREAT, and that's why the ODD parts.
That oil pad adaptor specially throws em off, and the aluminum retainers , and the head casting mark, hay if ya never lived (WORKED) in or on FARM equipment how would ya know.
I have worked on these very engines being from the Iowa farm community.
That's why i picked these engines up , i knew what they were 327s by the crank and date markings , just keeping things interesting here on the FABULOUS H.A.M.B.
GQQD job fellow hambers...

P.S. Ya can't ALWAYS count on those BOOKS or the INTERNET to find out information, sometimes it comes from the experience of being there.

 

The Retailer Just to shiny, Pop one off look where locks & spring ride .
I'm interested in that headmarking ,

 

Mystery 327 solved... the great peeps have figured it out .
The different and the odd are all engine specific to the MF( Massey Ferguson ).
MF combine engines have high nickel block with a steel crank.

 

A fun brain exercise. Thank you for keeping me up late

This was fun, thanks

 

Pretty cool, odd-ball expert stumper. I like it.

 

Learn something new everyday!

 

WOW farm equipment with "vette" motors
I bet it was faster than his neighbors tractors

 

Now for something totally different.
"How ya gonna keep em down on the farm once they've seen this".

I guess the odd head marking might be explained by the 7/16-14 thd on the one end for accessory mounting, maybe the ports are different for the 3200 governed RPM these things run at, are the exhaust valve stems 3/8" like 350 police/taxi heads, etc?
What I don't understand are the aluminum retainers on the intakes.

 

^ nope 11/32 .341's
spose MF wanted the intake retainers that way...
