It's been a while since l timed a 2.3 but l remember that they won't run at TDC. Seems like you have to move the distributor quite a bit to get it to run. Like set it so the vacuum advance is as far forward as possible, drop it in at TDC then move it around towards the rear. That could be why it's backfiring through the carb, the timing is that slow.

In a few minutes I will be out removing the old distributor and getting timing marks lined up to be ready to drop in the new distributor as soon as the mailman arrives.  Tracking shows it will be delivered today.  I will have a followup report later in the day.  Hopefully that it is running!

New distributor didn't show up today.  Local PO says the package still sits in the Rochester NY PO.  I won't see it till Monday.  I'm going to prep for the swap and I may pop the old one in for the heck of it and give it another whirl.

For whatever reason all shippers have been really screwy for the last couple weeks. I had something "guaranteed" to be here today and it's not. Earlier in the week I had five orders come in on the same day by different carriers that were early, late and on-time. Another was lost last week by Amazon and never arrived.

It runs!  :) Not well, or for any length of time but it fires and has some throttle response but I have no fuel system hooked up.  The gas tank is barely hanging by one strap and I don't want to put any gas in it.  Probably full of crud.  I don't know if the fuel pump is any good.  I may try to rig a one gallon gas can as a makeshift tank to see if I can get it to stay running for any length of time.  There are vacuum lines unplugged/uncapped so now that I know it will fire I'll see what I can do to make it run longer/better.

The timing marks on the crank pulley were rusted over and invisible.  I wire-wheeled all the way around until I could barely make them out.  I checked the orientation of crank and cam pulleys and they were right on but the distributor was off.  I pulled it out and re-positioned it and it fired up!  Still waiting for the new distributor to arrive.  Hopefully on Monday.

Thanks to all that offered advice and replies.  I will continue to update and ask questions as I move forward with my project.

Today I removed the supply and return lines from the fuel pump, extended the lines and dropped them into a 1-gallon gas can under the car and used that as a fuel cell.  It's on 4 jackstands so there is plenty of room under the car.  I got it to start and stay running.  I adjusted the idle up a little and played with the timing a bit and it will sit and idle without having to feather the throttle.  No knocking or other troubling noises.  When I put it in Drive and Reverse, nothing.  After adding 2 qts of Type F, it goes in both forward and reverse.  There is a terrible exhaust leak where the upper converter bolts to the exh manifold so it is loud and lots of fumes while under hood.  I'll have to get that tightened up to eliminate or minimize the leak.  I tried from above with 9/16, 5/8, 14 an 15  box ends, but none seemed to be the right size.  Can someone tell me what size it should be?  I'll try again another day from underneath with ratchet, socket, extension.

I made good progress this weekend; thanks again for all help provided.

Good news and bet your happy it runs , now you just have to chase out the grimlims out the car and look and see any future problems that may be hiding , you put in 2 qts of trans flude so did you see any leaks , it had to go somewhere , so check the vac line to the transmission for oil , if there is the modulator has a hole in it and will zoop the fluld out the trans , soon you will be driving it , have a good one

I didn't see any external leaks so it is a good possibility that the vacuum modulator diaphragm is bad.  I'll check that when I get under to either tighten the exh manifold or take apart for a new gasket.  The new distributor came in yesterday but I'm not messing with it until the weekend.  70 hour work weeks and 95 degree temps make me stay out of the garage. The weekend will be cooler rainy.  Good shop weather.
