Thanks a ton, everyone, now I have a lot of stuff to pinpoint in my troubleshooting I'll be sure to update as I go through it, too

I know this upgrade is in my truck's future; had to have major fuel injection repair work on my other 99 vortec Burb, around 200,000 IIRC. Was a few years ago so not sure. How much did the new spider assembly cost? Intake manifold gaskets are in the future too cause they are starting to seep, but this repair is beyond what I can do in my shed. I'd rather let a professional mechanic work on my truck to deal with getting the distributor back in correctly the first time. My luck isn't good enough that I want to attempt it and invite all the potential problems a screw up there can bring. Thanks for the helpYou must be registered for see images attach
I had almost an identical problem. You are on the right track questioning fuel delivery but you need to look under the air intake. I believe your fuel spider has gone bad. The original spider is single port injection. The new replacements are multi port injection. I replaced mine back in 2016. It took a couple hours and was not only a fix but a great upgrade. I have attached a picture of the old busted SPI spider and a couple pics of the new hotness MPI spider installed.You must be registered for see images attachYou must be registered for see images attach

Yes I forgot about that one! It will mess you up when it starts to go bad. Fortunately it's not that hard to do on a 5.7. Not sure on a 454, haven't seen one underneath.Another sensor that can go bad when hot is the crank position one.
Usually they cause the engine to stall when coming to a halt and a re-start is only possible once its cooled for 20-30 mins.
Thanks for the vote of confidence! My skill level, I probably can; the bigger issue is with my work space. Gravel driveway, no electricity so no extra lighting or power tools. When I did all the front end and brake work in 2018, the shop still had power, and I had room to put the truck inside and on stands, and I could lock it up overnight. Now that space is full of household stuff that wouldn't fit in the motel room or the trailer. So many people have had problems with the distributor reinstall that it has me nervous about that part of it.Seeping? To the outside and dribbling down the front of the engine?
By what I've read of your mechanicing efforts HWB, I can't see the manifold gasket defeating you. I think I may be doing mine this summer and the sticky 'how to' on this thread gives the low down on how to. Nothing too scary there - I'l wager you could do it.
