You mean a '49 8ba?

[adileo]

Yes

[JM 35 Sedan]

I put an 8ba engine in a 35 3w coupe many years ago, like late 50's/early 60's. I used either truck or merc water pumps, and recall having problems with fan to radiator clearance.
If I was doing this today, I would use an earlier cam, front mount distributor, and fan mount generator/alternator.

Thanks good idea, but Engine all together balanced. Any other thoughts?

When I put a '50 Merc in my '36, I ended up using an electric fan. Sorry.

Ya may have to go that route

I installed a 8BA engine in a '36 pickup in about 1963, don't recall any difficulties. I do know that we used a truck bell-housing and truck water pumps. As you will note from the pix, you will need a pair of '49-50 Merc motor mount spacers. These spacers compensate for the shorter "feet" on the water pumps and the slight offset of the mounting holes.
A friend of mine has an 8BA engine in a '37 pickup, pretty straight forward installation. I have attached a couple of pix of the engine in my friends '37.

Thanks I think there is a lot more room in pickup compared to a 35 coupe .

I was just going to mention that the early Ford PU's have move space between engine and radiator. Also, its been my experience that when using the 49 Mercury water pumps in this conversion, the U shaped spacers are required, but when using the truck water pumps, the U spacer is not required.

Seems like it would be easier to convert the motor to early style front and a mechanical fan before installing it; than changing it later when you get tired of dealing with an electric fan.

Our old friend Heard near Daytona, Florida has a cool little '36 3-window that some of you may remember from previous threads.



It has an 8BA in it, and it HAD an ugly, somewhat inefficient electric fan strapped to the rear side of the radiator when he bought the car. He wanted to get rid of the electric fan and come-up with a mechanical fan that would bolt-on to the 8BA, yet clear the rearward-slanted radiator found in '35s and '36s. So, we began to scratch our collective asses for a solution. Just so happens that I noticed a picture of the front of the 8BA in Jim Pullen's (19Fordy) beautiful '40 coupe. That picture showed a bracket that wasn't familiar to me, so I asked Jim what it was. Several years before, Jim had MANUFACTURED that bracket from scratch to hold a fan that would fit below his upper radiator hoses, yet also clear everything else that might get in the way.

Jim's bracket below:




Of course, Jim also came-up with the bearings and the other hardware necessary, as well as machining the fan hub/pulley parts to make it all work......beautiful craftsmanship!

So with that little homemade fan carrier bracket in mind, my wheels started turning. I came-up with a key (secret) element in the "Heard Fan" design which was the fan hub/bearing assembly out of an old Chevy Corvair. Yup, they were air-cooled with a big fan on top of the engine.





Heard procured a NOS Corvair hub and we started designing/fitting pieces from there. He mocked pieces from wood and fitted directly on the car. Heard eventually came-up with a full-sized, mocked-up wooden bracket. For the few folks that are thinking- "This is way too much trouble to go to for a fan"...Heard drove all the way over to Tampa and bought this Linley Jig Borer just to do the whittling! From there, he whittled (machined) the solid bracket to hold the Corvair fan hub. As you can see below, the bracket mounts to a '42-'48-ish fan bracket which bolts-on to the slide adjustment bolt on the front of the 8BA intake manifold. The pulleys are store-bought items. The alternator pulley drives the fan, if you're wondering. Heard had to carefully trim the angles and width on the rear slot of a double-belt alternator pulley, to accommodate the wider belt for the flathead. Ratios and pulley diameters were carefully considered from start to f
inish. It all worked-out really well, as this rig cools his 8BA very well on hot Florida summer days, while maintaining about 5/8" clearance between top of fan and the radiator. DD

Not sure this will be helpful .. I have a 1948 59A Flathead installed in my 35 Coupe - used a ford crab distributor and have a mechanical ford 6 blade fan in place. The engine was moved back 1/4 inch to allow proper radiator clearance - still have proper firewall clearance with no modification to the firewall. (Note clearance to firewall in picture)

I put a 1950 8CM Merc in a 1936 Ford pickup in 1959. Didn't have any clearance problems. Truck may be different though.

There is far more room between radiator and fan in a pick-up than in an automobile. DD

DD your post 12 includes the two words that best describe it - beautiful craftsmanship!

I shared it with my friend who has the 35 3 window coupe.

Andy....I much-appreciate your kind words, but you must realize that Heard is the one doing all the "craftsmanship"..... as usual, I just pointed and ran my mouth alot. Again, thank you! DD

Hi guys

I went to visit my friend today. Engine is in with the electric fan (no thermostats)

Car is running to hot. In garage, no hood on at idle car is 215/219 degrees with mechanical gauge and inferred gun. He’s thinking/hoping a shroud would help but running out of options.

Anyone have this setup, have found solution.

Tryin to help a friend out. He’s not too good with computers

[rotorwrench]

The engine may have other problems. Fabricating a shroud for the angle mounted radiators would be a difficult challenge. Others have gotten by without so that makes me think it could also be something else. Spark advance off can cause over heating. Blockage anywhere in the cooling system can cause overheating. A cylinder head gasket that leaks compression into the coolant system will cause overheating. I think I'd check those possibilities out before fabricating a shroud.

[adileo]

Thanks I’ll share that. I don’t think it’s cyl head as both sides have same temp. The shroud would be mounted on front of radiator where the electric fan is.
