Flathead Newbie Coil Question
 

4 Attachment(s)
Hi All, just been building for years but just got my first flathead V8 and I have what is hopefully an easy question.

I had a beautiful 36 Tudor fall into my lap and I'm converting it to 12V. It's a 21 stud V8 and the kit from Vintage Auto Garage came with a 3 bolt coil adapter. When I went to change it, it turns out I have a 37-41 2 screw coil. That's completely my fault I'll get back with the company.

Here's my question: When I tried to remove the 2 screw coil it came loose but the silver cylinder, that looks like a condenser, was holding the coil in place, the rest of the coil would lift but it was hung up there. Is there a trick to getting it off, I didn't want to mess anything up internally. I've attached a picture of the cap and a couple of the car for good measure. Appreciate the help -
Cheers!

Ryan

The condenser (the silver cylinder) is secured to the body of the distributor with a bolt.
The same bolt used to secure the distributor to the block...

Thanks I'll go back out an take a look, I couldn't see anything from either side and it felt like it was pulling internally when I tried to lift it off.

Unsnap and remove the distributor cap for better access to the bolt.

Also, cut and secure a piece of cardboard to the engine side of the radiator to protect the radiator fins from being smashed/bent while you're working in that area...

Consider a bosch blue super coil for your conversion. That is an extremely handsome car that just fell into your lap. Generally I am no fan of whitewalls, but the ones in your photo look great to me. I have read two types of whitewall threads here. One is 'how do I get my dirty whitewalls back to brilliant white?' , while others describe the use of tea bags to get that vintaged yellowed look ....

Thanks, we actually found the car at a garage sale, had a 4x6 card on the back window that just said "1936 Ford For Sale". I wasn't planning on buying a car but couldn't pass on it.

I haven't checked the date on the tires yet, they're bias 4 ply Coker, from the color I'd say they've been around a while. The car was rebuilt/ restored sometime before '08, the previous driver passed about 4 years ago and it had been sitting since. It actually belonged to the wife, she just never drove it, that's who I got it from. Unfortunately that's all the history I was able to get on it, there's been some upgrades: sealed beam lights, '40 juice brakes, polymer fuel tank, couple new gauges (oil / temp) under the dash and a battery kill switch. Everything else seems to have been done in a stock fashion.

Another option for a 12V coil would be to send an original 6V two screw type coil to George "Skip" Haney in Punta Gorda, Florida and have him rewind the coil for 12V. I think this is a better option than using some of those poorly designed adaptors and a remote cylindrical type coil.

PS.....congratulations on becoming the owner of a very nice '36 Ford Tudor sedan, and welcome to the Fordbarn. This is a great website for learning about these early Fords.

Thanks for the assist, got the coil off with no issues, I appreciate the information. one additional question: my coil is the "newer" 37 - 41 two screw design, when I got it cleaned up I'm not seeing a spacer plate for the retrofit. From what I've read that's indicative of an engine with updated cams, is that correct? It's a 21 stud head with the water inlets at the front.

Spacer between the distributor and the block. My reading led me to believe that the first gen flathead 8s had longer cams ("long snout") and if you wanted to run a later model distributor you needed a spacer plate... the exception being if the engine had been rebuilt it was likely that shorter cams were installed and no plate was needed. I have a first gen flathead with a 2 screw coil so I assumed that means the cams have been updated at some point.

Are you referring to this distributor to camshaft adapter? >
This adapter would be needed if you were trying to install a 1932-41 dizzy on 1942-48 engine...59AB Engine
