1935 block in 1934?

My 1934 engine had water in the oil and upon disassembly, I found huge crack repairs on both banks with a bolt running from outside the block to the valve galley. Also, deep rust pits in No. 4 cylinder and a hairline crack in No. 1 cyl.

I have located what appears to be a clean 1935 block recently disassembled that appears to be in great shape. Only crack found is between one of the stud holes and a water passage. Comes with crank, pistons etc. Std. bore with no ridge at top of cylinders.

My question is can I use the following parts from my '34 engine on the '35 ventilated engine? (Cylinder heads, intake manifold, oil pan etc.) Anything else I should be aware of?

You can use the 34 inlet manifold, but the 34 oilpan wont fit that later block....

Thanks. So what is different? The front or rear where it mates with the transmission? If the front of the oil pan is different, will it clear the tie rod or interfere with anything else up front? The '35 engine does come with the oil pan.

The front right of the vented block oil pan has a vent which protrudes downward.That corresponds to the engine block.

This shows the difference. More engine details are shown in the Techno pdf link in my signature. look for "Identify Ford Flathead V8 Engines".

Thanks for the photos glennpm. Unless I am looking at this wrong, the bolt hole pattern looks the same to me.


That vent feature appears to be internal and if I don't intend to utilize the crankcase ventilation, looks like I will be good with the 1934 pan. Just that the vent will be blocked off with the 1934 pan.


Thanks for the Techno Source Link.

Page 325 of your very informative Techno link states as follows.

To this day an owner of a 1932 through 1936 car can use a 1937 block, crank, and oil pan, block off plates, and all other original to the car parts to swap the late 21 stud motor into an earlier car (care must be used to make sure the pistons match the heads, either flat or dome type).

This answers my question. Looks like the '35 block can be used in the '34 with no fitment problems. :)
