I dont have hardly any room on the outside of the firewall to mount the ignition coil and no room on the engine. The dodge had the coil mounted inside the cab for some reason when I got it. Has anyone ran the coil inside under the dash and if so how much heat did it produce? enough to be bothersome in the summer? Thanks Jer
Iv done it …….. Works out good w chevy’s / distributor on the wrong end of the motor
Ok I will give it a shot otherwise I woud have to mount it out on the edge of the firewall. I didnt like that. Wrong side of the motor? hhmm my Hemi must have that to LOL Thanks
We ran them on O/T mud trucks inside the cab. Bit we also ran a brether tube into the cab to keep it dry. Tje coil should be alright the heat isnt enough that you should notice.
Just make sure the grommet is very thick between the wire and sheet metal or it could arc. Make sure the wire has slack on both ends to account for engien movement. And ALWAYS mount the coil with the terminals UP. We ran our coil in the air plenum on our stock car to keep it cool. weld on ........
Why should you always mount the coil with terminals up? I know most antique cars/trucks had the coil either mounted on its side or upside down like Chevrolets did in the 1920s-50s.
My old one was sideways if I remember. I have read post on it mainly leaking oil and not having the internals in the oil to cool it. I am sure some one can ad to this. I think I Looked up Coil mounting is what I searched for when I found the posts
I run all of the ignition components that can be moved under the dash. Makes for a cleaner engine compartment, and a water-safe one on hood-less cars in the event that you get trapped in the rain. I use a MSD coil wire pass-through for proper isolation.
Your '30 DB had the coil inside from new. And VW ran coils with the teminals pointing down on ALL the air cooled cars, never created a problem. That's over 16 million Beetles plus buses and Kommon Gears.
<<<<< Coil under the dash on that thing. No problems. Just keep and fuzzy type insulation away from the coil.
"And ALWAYS mount the coil with the terminals UP." I've had the coil upside down in my '37 for 20-some years with no ill effect.
I have everything but the coil mounted inside. I made a bracket and put the coil between the dist. and the carb. (small block chev), this gives me a clean firewall with the engine wires coming thru the lower lip of the firewall.
Chrysler products had the coil in the dash for years. They did it as an anti theft measure. The ignition switch was on the back of the coil, connected by an armored cable to the key switch. Made it practically impossible to hot wire.
Looks Good. my son has wired quite a few Street Rods. Mostly behind someone that wired themselves, and put those Cheap China Chromed Coils on Engine. They are like Santa, when he gets Hot, it shakes like a bowl of Jello. Everytime they get hot, they quit, ask Carlos ! Dont buy cheap shiney COILS, I don't like to put Coil on Chevy Engine.

Why not ? Henry Put all the Model T coils on the dash side of the firewall. 15 million of 'em all seemed to work ok. 4TTRUK
