    6.5 mechanical hackjob won't run smoothly

    So as the title implies I have a bit of a weird monster here. I pulled a 6.2 outta my k30 that decided it didn't want cylinder 2 anymore, and was given a good deal on a 1997+ 6.5 that had a dead DS4 but low miles and good compression, plus I wanted the turbo for a turbo 6.2 idea. However I saw...

    6.2 symptom confirmation

    As the title states I'm looking for confirmation or direction towards the issue in this diesel put of a truck I just bought. It's an 88 k30, 660 code 6.2 diesel non-egr. The truck has 70k on it and as far as I or the previous owner know it's the original engine. They sold it because it started...

    How to tell cabs apart

    I know variants of this question have been asked before but I can't seem to find the the answer I need. I'm looking at swapping the cab off my truck, an 85 K20 Silverado, with a spotless, but totally stripped out cab a friend of mine has for really cheap. Thing is, I don't know if it's a 73-80...

    6.2 diesel exhaust system

    So my truck needs an exhaust. Badly. I see they have full kits on lmc and such, but they only have them for the SB and bb engines, none for the 6.2. Would one of those kits for a SBC fit a 6.2? Or if not dido anybody know a place that has exhaust kits for these engines? Because I've been looking...

    TBI exhaust

    What's the best exhaust for a 350 TBI. It's git long tube headers with twin 2 1/2 pipes down to two raptor mufflers. I was looking into new mufflers since the raptors not only sound pretty bad but they're kinda shot. What do you guys recommend for a more agressive sound? I would just run...

    Intakes

    Are the intakes for a TBI and a carb interchangable? There's a good deal on an intake, but it's for a carb. Will my tbi bolt onto it? I can't find anything about bolt patterns and fitment, and I don't wanna waste my money if I can't put my tbi on it

    High beam issue

    All four of my headlights do work. However, the top two headlights are low beams. When the highs are turned on, the bottom two are supposed to come on as well. However, when I flip on the high beams, the driver's side has an issue. The top headlight turns off, and the bottom turns on. Anybody...

    454 vs 350 injector bowl

    I found that my injector bowl was cracked on my 87 TBI 350. A friend had a TBI off an 88 454 TBI. The injector bowls were the same size and my injectors fit into it, but it needed a taller gasket/spacer between the base of the bowls and the throttle body. It now leaks gas profusely from...

    Random idle stumble

    One issue to the next. After sorting out my fuel issue, the truck ran fine for a week. I replaced the fuel pump relay, and rebuilt the TB. Now I've noticed that once it heats up enough to get to low idle, it will randomly stumble/almost die before reving back up to idle speed. I don't have the...

Anyway, after my fuel pump finally went yesterday, I replaced the fuel pump relay and the pump. Now the truck idles like it's running on alcohol, but once I get on the gas and start driving it...

    Can anyone here find or know of any diagrams that show which wires on the fuse box plug in the engine bay go to which fuse? I have looked and looked and cannot find any. I need to know because I want to check the ignition wires, and my injectors have to be hooked back up, but I don't know which...

    Kick panels

    My 87 v10 silverado has kickpanels, or at lat one on the passenger side. My issue is that they're vacuum operated, and i have no idea how the hoses run or where they go to, as my engine bay is missing some vacuum lines and I have no diagrams. Id like for them to work, as the AC is not in working...

    Ecm

    Do the ecms differ in the 87 v10 for the 305 engine and the 350? My truck was originally a 305 according to vin (HXHF) but the previous owner claims the engine that was swapped into it is a 350. Is there any difference in the ecms used for each engine or are they the same?

    ISO TBI vacuum digrams

    I have an 87 v10 Silverado. It's missing many vacuum lines, as well as has some it doesn't need for egr ECT. While I'm rewiring it, I'd like to get the vacuum lines straightened out, and was wondering if anyone on here has any diagrams for the lines, as I cannot find them

    Vortec heads

    I have an 87 k10, so it's got the TBI. However, the block in it is older, meant for a carburator. The TBI top end bolted right up to it apparently though, since it runs with no issues. However, what needs to be done for a vortec head swap, or would it even be possible with this block? And how...

    Popping/backfiring

    I recently bought a 1987 chevy k10 with the 350 tbi. I just got it registered yesterday, and drove it more than ten feet for the first time today. It had run fine in my driveway every time i ran it over the past two weeks. I bought a few gallons of gas before I tried to drive it because the...
