1978 Jeep CJ7 distributor issues

My Jeep came with a GMC distributor using a ACDelco D332 cap. This was done by the PO most likely to get away from the stock point system.
Which has been working fine for a while.

Now I have to do a tune up and I’m kind of stumped. What is the firing order? What cables do I use with this type of distributor?

I’m using order 153624 but it’s not right.
This distributor is confusing the heck out of me.

I’m running the i258

Hi distributor does not determen the firing order.. be sure you have it going the right direction , I'm not sure which way is right. but you can pull the cap off and hit the starter and see which way it goes.. and make sure #1 is in the right spot. . TDC comes up twice on the crank to one turn of the distributor. one is exhaust TDC and the other is what you want for Timing of TDC. So you could be 180* out if you timed it the the wrong one.
good luck

Thanks i figured out the 1 position.
My Jeep got submersed while mudding.

It hasn't run right since then. I think maybe have water in the gas or maybe my coil is bad now.

Hi If it got water in the cylinders then you may have some bent piston rods, or push rods and maybe bent valves... I'd start by pulling the valve cover and check for bent push rods way loose rockers..

good luck

No water got into the cylinders. The engine oil is clean. Water got into the distributor cap, possibly gas and exhaust. Not in the engine.

The engine starts and sounds fine but loses power on load acceleration.
