    Aftermarket trip computer for OBD1???

    It showed current fuel mpg. Injectors are rated in lbs. per hour but don't remember what the Vettes are. Injector Flow Rate Naturally Aspirated Engine Engine w/ Power Adder 24 lbs./hr. 280-360 hp 240-300 hp 30 lbs./hr. 350-450 hp 300-375 hp 36 lbs./hr. 425-540 hp 350-450 hp 42...

    Aftermarket trip computer for OBD1???

    Well, the Vette (1987) uses a TPI system. I don't know if it uses a flow meter to calculate fuel use, or if it uses injector open times. I personally don't know if the factories offered trip computers on TBI or not. I don't understand how it could be problematic... Functionally, for what we...

    Synchro NP205 Transfer Twin Stick Mod???

    I may be mixing up some of what I am stating with the 1976 Blazer I also had. It's a 69 year old memory to deal with here. The truck is stored 6 hours away at the moment. So, here's what I know for certain: 1980 GMC Jimmy with 350 V8 and 205 transfer case. Turbo 350 Locking hubs. (I thought...

    Synchro NP205 Transfer Twin Stick Mod???

    By looking at bearing cover. Plus, it used to be "full time 4wd" and I added the locking hubs. Vettepilot

    Synchro NP205 Transfer Twin Stick Mod???

    I don't need lower gearing at all for my use. I just want twin stick operation, and the ability to switch to front wheel drive only when needed. Thanks, Vettepilot

    Synchro NP205 Transfer Twin Stick Mod???

    Hiya, I bet this has been well covered, but I can't find anything definitive and/or recent. 1980 Blazer with synchro NP205. I want to twin stick it, and I want to have 2 wheel front only capability for various reasons. This is all well covered for non-synchro 205's. But what about synchro...

    Whining alternator on my ‘94

    I will add this. I seriously doubt the "250 amp" claim in that Amazon ad. These alternators are capable of that with mods, but I doubt this one would put out that much. It should however, put out a solid 145 amps, and do so at low rpms. Vettepilot

    Whining alternator on my ‘94

    Here's the one I got. The bolt spacing is close to correct, and will fit with some grinding to one of the mounting holes, as others have reported: If you buy the incorrect one, for a car, you will see what this picture shows. The diagram shows the two different mounting hole schemes; narrow...

    Whining alternator on my ‘94

    Thanks. I believe I've got it figured out. I'm converting my truck to an AD244 heavy duty, high amp alternator. Caution to all doing this: The AD244 alternators for cars have a bolt pattern that is about 3/4" wider apart than the AD244's for trucks, and they will not fit. When converting...

    Headers, headers, HEADERS??

    I have GREAT luck with cheap headers. Last set on a Blazer did not need touched until the Mexico salt air rusted them clean through after nearly 20 years. I saw cut the flanges in two between each cylinder. Then I used TWO gaskets coated with silicone. Re-tighten twice after warm up-->...

    Headers, headers, HEADERS??

    I don't know why, but the factory OEM's were the last one to get the "memo" about how much a good exhaust boosts performance, if they ever got it at all. Someone will say "longevity". My last set of headers was the very cheapest I could find that I put on my 1980 big block Blazer. It was my...

    High output alternator

    Ok guys, I think I finally got the scoop on this, after hours of research. I am somewhat at a loss as to why this info was difficult to find. The TBI trucks sometimes seem like they're the "red-headed stepchild" and quite neglected regarding available info. Not all of us have Vortecs, even if...
