Flathead head identification for 68-6049B and 68-6050B
Thomas J Teixeira
I have a '35 Ford pickup with cast iron heads. The heads have casting
numbers 68-6049B and 68-6050B on the left and right head (I may have
them reversed here).
The block looks like it is from '37 or '38 but has the water pump
outlets blocked off with a plate of some kind and older water pumps
attached to the front of the cylinder heads.
The books I have found said that 21-stud heads were cast iron in 1932
and there were some high compression cast iron heads for 1937. All
the other cast iron heads were low compression heads for truck engines.
Does anyone know what year and application these heads are originally from?

I think you have 1936 heads. I have seen conflicting information, so I'm
not too willing to take a firm stand on this.

I also think they're from a '36 since '68' is the model designation for the
'36 engines. I received one reply from CJ Shakoske who thought they were 90 hp
heads from '36 which would be good news. I think the other possibilitiy is
that they could be low compression truck heads from '36.

The information I posted was from 1928-1948 Ford Chassis Parts
Catalog(Green Bible).
Hope this helps.

Hi, Tom:
Based on my experiences/research while owning & trying to
restore two 36 Fords (5 window coupe & 2 door flatback), I'd say that
the previous answers are correct in that the "68" indicates 36 parts.
35 heads would (should) have part nrs. beginning w/ "48". I did quite
a lot of research on mechanical parts when I had my two V8s, and I'm
pretty sure(?) that cast iron heads were only used on "commercial
vehicles" at that time ; the (U.S. produced) passenger cars used
aluminum heads . Never heard that the iron heads were "lower
compression", though.
Also, (despite what the Green Book may say, the official
rating f/Ford passenger V8's in 35/36 was 85 HP, not 90. Of course, I
have also heard that Henry may well have played kinda "fast & loose"
w/the true HP specs, and that a lot of his engines from that era
actually produce rather more than the stated HP. Anyone have any
hsitorical data on this?
FYI: both 35 & 36 V8's came with the water pumps mounted to
the front of the heads. If your block has "block off" plates, sounds
like someone, somewhere in the past mis-mated a later (37 or later) 21
stud block to 36 truck heads. Not too unusual, but not (IMHO) a eral
great idea. I'd either look for a complete 35 truck engine, or use
the (MUCH more efficient) post-36 pumps that mount to the block. Just
my opinion.

Yes, that seems to be true. Unfortunately, the only 21-stud blocks with the
later water pump are for '37 and '38 and I'm guessing that they need a very
different style of head, or at least some radiator hose fitting to use in lieu
of the water pump.
The engine and transmission are already in this truck. I'm just trying to
finish things up and was doing some research to find out more about what's in
it (the guy who did most of the work is now in a nursing home). If I were
going to put in a different engine I would probably look for a 46-48 engine,
or at least something with 24 studs.
The differential seems to have 3.54 gears. I removed the speedometer sender
from the drive train so I could see the drive shaft turn inside the torque
tube and jacked up one rear wheel. Two revolutions of the drive took about 1
and 1/8 revolutions of the wheel.
Anyway, thanks for the input!
