Mind look into converting the distributor to crab style cap. New cap, rotor, wires, clips to hold down crab cap. Have fun with your flathead. Mike

Bob Drake has a nice set of one piece radiator hoses. They have the correct bends for your engine.

I measured it at approximately 25" so they are fairly long.

Next, distributor cap and wire sets...? I would like to know what has worked well for others so I don't waste funds...

Eventually I would like to gravitate towards 12v but if that isn't recommended please also advise...

Were do you want to be?

Lot's to think about when going through a motor. Hows your compression or bearings? Not even thinking about brakes and stopping...

If you just want to get up and running. Stay 6v and get the systems that are there already clean and ready to run. Most likely it'll run for a few or 70 more years. Burnouts excluded.

Most of the general supply places have hoses and dizzy parts.

If you know where you want to be electronically and feel you know what you want out of the engine. You can make a plan.

If you want to have fun driving it as is... clean the oil pan, block, rad, and send the coil and dizzy off to skip and bubba. Chase or replace wire harnesses as needed.


If you want to go whole hog. Start talking to rebuilders and buying parts.


I picked up a 36 coupe 5yrs ago that needed everything to complete it. But I replaced a burnt exhaust valve for $7 (compression good outside that cylinder, oil pressure nice), recored the radiator, replaced all the electric, rebuilt the coil (skip), did the dizzy (bubba), and went through the rest of it. Been driving it ever since. Took about 6 months to be road worthy. It's no luxury air ride deal or tire burner, but I like it.

Remove spark plugs, put a little MMO in the cylinders and a rag over the holes
so you don't make a big mess. I would have a mechanical oil pressure gauge
on it. Spin with 12 volts to the starter. The pressure you read will be what you
have at 45 MPH. If the pressure is real low the front bypass or the pump
spring may be weak. G.M.

i was going to change out my wires with a new set of uncut 8mm and wondered if 6v would be a problem....has anyone had issues with similar?

Your car will run fine with a 6 volt system. Only reason to switch to 12 volt would be that you want to run some 12 volt devices.

The 47 uses a rabbit ears distributor cap. I tried switching to a crab distributor cap but found that it is affected by moisture and will run rough or just plain not run. So I switched back to the rabbit ears.

Sending the distributor to Bubba's along with new plugs, wires, caps and rotor would be a good idea for long term reliability.

47 did you try spraying the crab with WD 40?

Looks like someone already changed-out your OE distributor for a good-old crabby. I second having Bubba (or Charlie NY) do you distributor and recommend staying with the stock points set up. My '47 came with an electronic unit in the distributor but had so much trouble with burn-outs I converted back to stock points (very pricey experience) .... all good ever since.
