Coil mounting suggestions on Flathead with crab style distributor?

    Where do you guys mount the coils on flatheads with crab style distributors in a open engine roadster? I used to mount it horizontally with a fabricated clamp off one of the front head bolts. However, now I start to think there might be better solutions out there to avoid vibration and heat to the coil.
    Let's see some elegant solutions.

    I don't have an open engine, but I used the original stand for the 6 volt coil and then bolted a universal coil mount to it to hold the coil. The coil stand is bolted to the engine and the coil is vertical.

    I really like the stocker, the one used on '42-48 V8's that mounts over the left front pair of bolts on the manifold. Holds coil up a bit from hot stuff, right behind fan, but still tucks it in nicely so it looks integrated with engine. If using dual coils or if I need right mount to clear I would work on slicing and dicing to make a mirror image...
    I have used this mount with stock Ford coil, with common modern cylindrical coild mounted hrizontally, and with a huge, awkward rectangular 1970 vintage Mallory.
    Most vintage dual coils setups hung coils in that same neighborhood one way or another.
    Evans made a cast-aluminum version designed to go at front of manifold and hang two '48 coils for a Harmon Collins...just recently found a poor picture of that. Never knew it had existed before.

    Van Pelt site reproduces an overhaul manual pic that at least shows the location: http://www.vanpeltsales.com/FH_web/.../Flathead_Engine_complete1942-48-leftside.jpg

    Thanks guys. The intake mounting is an interesting option.
    Finned heads probably don't allow the use of the stock coil mount.

    Here is a link to a pic of the stock 8BA coil mount

    Does anybody sell aluminum mounts for finned heads? I think I remember seeing something, but of course can't find them anymore.

    The bracket I refer too is functionally just a 90 degree piece of steel...two holes at botton that bolt to front two manifold bolts, staggered so bracket is parallel to engine axis, and two holes at top to take coil...
    but like most early Ford bits it has some style. Bottom is scalloped to follow around manifold protuberences, top with the two holes is like Mickey Mouse ears.
    I think much better design than 8BA because is up above manifold rather than clamped to a blazing cylinder head, and is right in line with fan air and directly above the coil socket in the Crab...after all, this is the bracket designed for the crab in 1942!

    I just recently had my first experience with a leaking coil. I know, very rare, but if it had been mounted horizontally there would have been a bigger mess beyond merely breaking down on the side of the road.
     
  7. I just went through this two weeks ago. I ended up making a bracket coming off the LH water pump upper bolts, the coil sits in front of the LH head just above the block and parralel with the block surface. Looks good to me, sorry no pic.
     
  8. Yep, thats how i mounted mine!

    Don't know if it would work on yours, I have a crank mounted fan and offset generator on my 40 so I made a bracket that bolts to the manifold's original generator/ fan mount. Got a little carried away with carving up aluminum to make it on this one, on our 39 I just made a simple L bracket out of steel. Both take an aftermarket chrome strap clamp bolted to the fabbed L bracket.

    I mounted mine off the inlet. Just made a simple double right angled bracket and cut off one of the mounting 'feet' from the coil bracket. Not particularly fancy but I like the position and it doesn't seem to suffer much with vibration.
    Oh and look, a leaky 97! Now there is a novelty :);)

    I mounted mine on the firewall in the stock Model A position. The coil lead is a bit long but it seems to work well.

    Ukgav - nice solution.
    Does anybody know if coils are NOT supposed to be clamped in horizontal position?

    It maters on what type or brand of coil it is. Some yes and some no. The instructions will tell you.
     
  14. That's about how I mounted mine. I just replaced the mallory 6v coil with an nos Echlin 6v coil my cousin had. I mounted it in the same position. My car would not start when up to full temp. It now starts fine all the time. Not sure if position caused problem. will see what happens with new coil.
