In my area a gentleman is selling a factory GM JH coded motor that he says has never been ran or opened up and the heads are still welded to the block from the factory. Sure enough on the back of the motor there are small welds to the heads and block. Did GM weld its BBC heads to the blocks? I have never seen such a thing. It's a nice looking motor, no VIN, so probably a crate motor.
Were BBC heads "welded" to block from the factory?

:noway: never saw a 'welder' on the final line 
Are you sure it isn't a 'goop' of Aviation 'Form-A-Gasket' #1 squirted there to stop the corner intake leaks that's dried
ps: not an 'expert' - just never saw a factory 'weld' on production GM engine block ...

I'll agree that it never happened. I've welded some and understand the process on cast iron welding, it's just hard to call BS on someone with such a nice motor. http://www.ksl.com/index.php?nid=218&ad=11383350&cat=&lpid=&search=camaro
THE MOTOR HAS CLEARLY BEEN APART?
A TRANSMISION HAS DEFINATLY BEEN BOLTED TO THE BLOCK!
THE TELL TALE SIGN OF THE BELL HOUSING BOLT THREADS ARE GONE / ALTERED?
im sure im not the only one that sees that?
those arent the right heads for that block according to gm docs?

:noway: Uhmmmmm - no
How would a dealer (or anyone else for that matter) get the 'back of the block' to weld it if it were 'the original' in a car
Story is getting worse by the min ....
It's not stamped so i'm thinking it's a CE or left over NOS.:noway: Uhmmmmm - no

I'd be willing to bet the Partial is down by the filter - he just can't see it
It's a mish-mash of parts - no telling what you'd find inside - OH WAIT - that could why it's 'welded' shut l
ps: Looking at the 'welds' in higher res. it looks like those "welds" are really gasket sealer 'runs' from the manifold (which isn't bolted on) gasket area The one on the passenger side rear looks like a sealant 'goober' or a really $hitty weld ...

lYEP, I would put money on John being correct on the VIN being down by the oil filter.I'd be willing to bet the Partial is down by the filter - he just can't see it

All warranty blocks (CE blocks) got stamped starting in 68. JH is a 69 code, so there you go. Check the oil filter area / bellhousing flange.
Now that I took a look at the pics, I don't see any welding.
Bill,
I am normally pretty sharp, but you lost me.
Are you quoting something from somewhere?
For a JH block, 291 heads (3964291) heads are OK.
I just saw the head casting numbers are different.
I would say it is POSSIBLE that it could happen but not likely. Both are rectangle port heads. 840 heads were used into 69, and the 291s started in 69. Depends on the dates. I think there was a small amount of overlap on useage.
Picture is not the greatest, but I think I see factory broach marks. I can't say for sure if it's legit or not. But maybe Kurt can take a look at it.
