Is this original engine?
 

1936 Ford 4dr

Is a 24 stud engine original to the 1936 model year?

Were aluminum heads also cast 59AB?

I want to connect the existing accessory hot water heater that is mounted to the interior firewall. I looks like the ports next to the cylinder head water outlet might be a great place to capture hot water to send INTO the heater core, or is there a better place to capture the hot water for the heater?

Where is a good spot to RETURN the heater water back into the cooling system?

Thanks in advance

your engine is post war 46-48. one way for heater return is a fitting that goes on lower radiator hose.

Made in Canada heads were alum., at least part of them and high comp. knock off heads were built in the US. A normal US built 24 stud would have cast iron heads. 36's had 21 studs with water pumps in the heads.

Are those aluminum or just painted silver? Looks like rust stains showing through.

There are period aftermarket w/pumps that have a NPT female port for the heater return hose fitting.Much better than poking a hole in the bottom radiator hose and using that fitting that is prone to leaking.JMO.

I'm with Deuce Lover - I like the heater return hose that goes into the side of the Passenger side water pump. BUT - I don't know of anybody whose modern castings actually have that NPT fitting in the casting. Anybody know of one?

Its quite easy to drill and tap your own port on the pump. Like this, 59a in a 34

The easy way to hook up a hot water heater in a '36 w/59 AB engine is to utilize the port in the right head adjacent to the inlet into the head. Use a manual heater valve so you can turn the hot water off in the summer.
In spite of the earlier comment about the return line to the lower radiator hose being problematic, I disagree. Using the correct off-set lower hose that is sold by most aftermarket vendors, it is very easy to install the correct fitting into the hose, which is a simple,. trouble free installation.
I would also suggest that you purchase a correct after market upper hose that makes allowance for the required off-set in the radiator tubes and heads.
As you can note in the attached pix, I had the flex hoses on the 59AB engine in my '36 for many years, I know have the after market off-set hoses.

I have one of those 36 water pumps with the heater hose return in the pump. It is a genuine Ford service replacement pump including the part number. correct grease fitting and brass grease fitting hole plug. It works on either side of block. $75.00 to your door. Lemme know if you want it.

His engine is a 59-AB, so it has to be a later 37-48 style pump.

Yeah,, I realized that and tried unsuccessfully to correct/delete my post but wound up posting twice so I gave up.

As mentioned by JimTN. Canadian heads were aluminum for 24 bolt 59a. Cheater heads in the roundy-round crowd. After 50-70 yrs I wouldn't assume anything is original to the line. 21 bolt fords went till mid/late 38. Then 24 bolt. 81a, 99, 59 etc...


If you had a 37/early 38 block you would have a 21 bolt heads with center head water outlets that can bolt to a 36. Only issue is there is no lower block water pumps into the block. You can however put a 37 block in a 36 and block off a few holes and run head water pumps.


Just a stupid thought.

24 bolt, non finned original heads should have made in Canada embossed. Just ground out. Think I see a few letters in your picture post. If I'm right or seeing it right. Not mine, but for reference pulled off the internet. Believe they are 7.5:1 verses 6:1 stock iron.

Re: Is this original engine?
 

C7RA; 81A; and 91A are the only aluminum factory made in Canada 24 stud centre outlet heads I’ve seen.

Re: Is this original engine?
 

UPDATE: These are iron heads painted silver.

CONCLUSION: The engine swap to a post war V8 was probably relatively simple and not uncommon on this 85 year old car when the original engine was in need of "significant" work.

Thanks for all your input.

I finally saw one of these elusive 1938 V8s with a 21 stud in person. It threw me for a moment.

Very cool vehicle that solidifies the history.

The 37 block was installed into early-mid 38 trucks. Installed the end of the run of blocks that were made in 37.
