Another Conversion

[53 Catalina 292]

Did you try replacing the oil pressure switch with one calibrated , if that's the fancy word I want, for a light instead of a gauge? And I'm thinking that you will need the temp gauge sender calibrated for a light, too. Is there a reason you don't want to use the original location in the cylinder head for the temp sender? Maybe you want one location for the light and one for a switch for an electric cooling fan? (Good plan, in my view.)
Other than the manifold adapter and the distributor, which you've posted about, what were the other issues you ran into before getting the TBI system running? I'm hoping to find an Astro/Safari or other 4.3 donor for the PCM, or maybe just the PROM, to run my Caprice system for my conversion. Johnny Cash would be so proud. But 4.3s of that vintage are few and far between hereabouts. There's one I see nearby, but it's still in service, so if I were to appropriate the PCM, I figure the guy would miss it sooner or later. (Comedians everywhere looking for work, and I'm trying to be funny. Shame on me.)

Okay, so as to what one of the guys said before. Its about time I upgrade the gauges any rate, so. I'm gonnna order a new bezel when I save up for it. But first thing is replacing my lower thermostat housing so I can relocate the coolant temp switch to the housing and install a coolant temp probe for the gauge in the head. Its up and running right now but I need to wire in the c.e.l. To a place on my dash somewhere before I start driving it. And I need to tune the chip as well.

as for your question for original location. Its right over the exhaust manifold currently. And I think it would be better suited at the front of the engine.

There was a balloon in one of your posts, from Fast 355, saying you need the 4.3 injectors, PROM chip and netres pack. You didn't know what he meant, (wish I did), but you already had the 4.3 injectors and PROM chip. I don't know if the reason you need the 4.3 PROM is because of number of cylinders or engine size, or both. Did you ever find out what netres pack means?
I just saw the pictures you posted - late 60s Chevy pickup? Them was purty thangs. Or maybe I just think so because they were new when I was young.

I believe i do have the 4.3 injectors(size of engine/injectors closest match i believe) same for the p-rom. But i still dont know whatthe netres pack is... And yes 69 chevy c10 my dad handed down to me. I helped him rebuild that engine a few times. I also remember the choke fouling up many o camping trips. And he would find a way to make it work lol. But when i got it. I found plenty of things he did that were no good and i had to repair n replace. Lol. This truck is fond memories for me. Its never gonna go anywhere till i die and hopefully it will go to my kids.

After a short search i found on this site netres is the limp home mode for the engine.. This p-rom and netres pack and wire harness and sensors all came off a 91 astro van v6 4.3l. Now i just need to program the p-rom for the right 4.1l engine.

Nice to have a vehicle with happy family memories - who'd guess that the nuisance of having choke trouble on a camping trip would trigger good memories decades later? Kind of shows to go ya not to sweat the small stuff. I have a 91 Cutlass Cruiser handed down to me by my folks, now gone to be with the Lord, that I'm occasionally working at getting back in shape. Thanks for the research and info about netres pack. Is that built into the PCM, do you think, or a separate module? The need for programming surprises me, the size of the engine fed by your donor system and your engine size being so close. In my ignorance, I wonder if substituting one injector from a 2.8 or 2.5 TBI would lean the idle mix, and still give you enough at wide open throttle. If the computer just regulates pulse width, and the injector nozzle flows less, hmmm. Nah, too simple - couldn't possibly work. Or could it?

I think the netres pack is the soldered chip next to the p-rom. As for the smaller injector i kinda like the idea of programming it better. But i will go look at the tbi units at the yard. But most of them have 1 bbl for the smaller units with same size injector
