64 Imperial Fires Up

[Xcudame]

So I was very happy today when the beasty fired up! I had to add three spark plug wires (one was mia and the other two were visible broken. Somewhere in my barn is a box full of spark plug wires, but I couldn't find it. So two new sets are on the way. And no, I could bare to rob wires from my 70 Challenger!

So best I can tell, the mechanical fuel pump is not working. I had hooked the suction side up to a five gallon gas can, and nothing pumped out once the carburetor fuel bowls emptied after I filled them. So another part to buy - fuel pump.

Since there seems to have been some kind of massive coolant leak at the thermostat housing, I going to just pull the whole front end off and replace the housing, water pump, fuel pump, radiator, timing chain set, camshaft and lifters and pushrods. Then rebuild the carburetor.

While I'm in there can anyone thing of anything else?

When you take the old pump out, do one more step and pull the pushrod out and check the length. Should be 3.22".

Good call! I have a new one if the old one is too short!

Here's a photo of the coolant leak!

Probably the hose, based on how old the hoses and clamp look.

One of the heater hoses snap in half it's so brittle and dry rotted. Will definitely be replacing all the hoses. Vacuum hoses look pretty shot too.

Changed out spark plugs and added new spark plugs wires. Hooked up a $10 electric fuel pump and she runs good! Need to rebuild the carburetor while I'm at it! Too bad I can't upload a nine second video of it running!

If you have YouTube you can upload it there and then paste the link here. Only way for video it seems.

I use Vimeo. Free and fairly easy to use.

That car will be nice when you get it all sorted out.

Got the front end tore off today. Going to use an aluminum water pump housing and pump I have on the shelf. Got the fuel pump off and it matches the one on the shelf as well! And the fuel pump rod measured 3.22" the same as my brand new one (hat tip: Big_John). So no need to change out the camshaft at this time. Got new hoses and belts on order.

Does anyone run Chrysler factory electronic ignition on their early cars? I know people use PerTronix HEI ignition, but I have never had an issue with Chrysler electronic ignition.

Either one will work. I have one car with an older Mopar electronic and one with Pertronix. Both start and run well with no problems.

IMHO, since the new Mopar electronic ignition kits are offshore sourced, I would lean towards buying a rebuilt electronic distributor with the GM style HEI from @halifaxhops For Sale - a B and a RB rebuilt electronic distributors with HEI

The Pertronix Ignitor II works well and has built in circuit protection that the Ignitor I didn't have, so that's another good choice.

Luckily I have old ECUs on the shelf! If you guys (and gals) could see my shelves, you'd think you were in Mopar heaven! 35+ years of collecting mostly engine parts.
