    Solving gauge mysteries

    I'm in a middle of what I though will be a quick gauge bulb change that ended up being dashboard disassembled, checking gauges, cleaning and troubleshooting. All thanks to those odd (for me) bulbs that look like regular W5W or W3W, but are integrated into plastic sockets that need to be pulled...

    Another oil pressure gauge thread

    Okay I figured it out, the pinout on that MS Paint drawing was incorrect! However I traced the wires visible on the actial picture and found that the sender unit is to be connected on the other side I happen to have couple of 47 resistors on hand. My 0-60 gauge shows 0 when "sensor" is...

    Another oil pressure gauge thread

    Thank you, I have something that looks like a thick film ceramic resistor screwed to the back of the gauge, so I'll check it. My gauge reads 0 - 30 - 60, however with voltage between two posts it went way past the 60. Based on your diagram I've applied the voltage on just one of the coils which...

    Another oil pressure gauge thread

    Bumpong an old thread, but I just now happen to have the gauge cluster to change bulbs and inspect gauges. My oil gauge is showing something, shows pressure with engine off, shows some different pressure with engine on, does not react to throttle. I want to bench test it while I have it out...

    Welcome from Poland!

    After reading so much about 305's I passed on couple of cars, including a rusty Blazer for a good price that would be probably even more fun to tinker with (definitely would fit into the garage better! :) ) due to them having 305 and not 350.

    Barn doors and door questions

    I took some pictures: that's how the barn door opening looks in my burb, you can see daylight from the inside with the doors fully closed

    Barn doors and door questions

    Hi again, My barn doors are rattling, they seem to latch correctly (can be latched either on one "click" or deeper on a 2nd "click"), however after closing they have still some play, can be pushed in compressing the gasket. Those latch ears are adjusted as far in as possible while the latches in...

    Automatic transmission newbie asking basic questions

    Valve float limiter :) What's the max safe rpm for a stock 350 TBI? 4000 - 4500 ?

    Automatic transmission newbie asking basic questions

    Thanks a lot, however the fact that a computer controlled engine could have no rev limiter is also a new thing to me! I'm considering adding a tachometer and learning what's the no-go zone for a stock truck 350 TBI. I've read a lot about the TV cable and based on the overall feel vs it appears...

    Automatic transmission newbie asking basic questions

    I'm new to automatic transmission, especially of a mechanically controlled type. I have a 700R4 and I wonder how idiot-proof it is. While I was cruising in OD at I think around 35 mph and passed a tiny hill the trans downshifted to 3rd, then it did what if felt like couple of times shifting...

    power window relay mod

    I'm also fighting slow power windows. Greasing the guides helped, however windows are still too slow. Windows go noticeably faster when controlled from the door switch than from the master switches on drivers door, so the issue is related to lenghth of wires and the fact that both ground and...

    Adding a headrest to a bench seat

    I wonder do you have something like this available in the US? It is a slide-on headrest, an accessory from a 70's Fiat 126p. These slid onto factory low back seat and added some whiplash protection. When matched with the factory upholstery it looked like a seat with integrated headrest.

    Ideas for missing headliner

    That's an interesting option, thank you for the idea, I've searched how does it look and it's not bad! Once the fabric is tensioned it is hard to tell that it is not glued to something rigid. And the shipping would be way easier than a giant flat box. that's way over my woodworking skill level...

    Ideas for missing headliner

    Not sure what kind of headliner it is... Interesting idea, would probably work like a butyl sound deadening mat. However I can't imagine how to apply ot on a roof w/o removing whole interior to get it do.e

    Options for tuning of Gen1 TBI in 2023

    For the price of a Haltech one can get a Sniper EFI, so that doesn't seem to be a cost effective. Good thing that GM TBI is not a forgotten tech and there is still some aftermarket supporting it :)

    Options for tuning of Gen1 TBI in 2023

    Is it like a pre-programmed chip that you cannot reprogram? That also sounds good and I don't mean the name ;) Will google around.

    Options for tuning of Gen1 TBI in 2023

    That Dynamic EFI looks like something I was looking for! I've been on that page but by looking how it looks like it was last updated in the 90's I judged that this product is probably no longer available :) And I agree that unless I'm doing some major changes then a tuning won't be needed, a...

    Options for tuning of Gen1 TBI in 2023

    Hi, I'm trying to find out what are the options for tuning of the 1990 TBI system these days. From what I've learned the ECU has a PROM memory, a one-time programmable chip that stores the base tune and adjustments are done on the go using inputs mostly from O2 sensors. That's similar to what...

    Can you add a dome light to a truck

    Speaking of a dome light, or more a dome light wiring: Is there a way to turn it off? So far I've found that a light switch doubles as a dimmer dimmer and a dash dimmer doubles as a dome light ON switch, but I have not found how to permanently turn the lights off. It's bit annoying to disconnect...

    Ideas for missing headliner

    Availability of building materials is also slightly different than in US, like I've never seen plastic wallboards in bathrooms, however there are some PVC boards available at our DIY/construction shops. Luan board seems also like a good choice, thanks for ideas!

    Ideas for missing headliner

    Hi, In the Suburban I bought there is no headliner, not even the moldings, I have just bare metal roof. I know that $529.95 can get me a headliner from LMC, however shipping is an issue as I'm in Poland. I've searched the forums and I coudn't find if anyone has ever made a headliner from...

    Welcome from Poland!

    I don't want to go crazy with anything, however this thing could have a little bit more power out of that 350 cubic inches.
