98 GMC k3500 454 (7.4L) Distributor Install 

Good ole wobble socket for distributor hold down bolt. Well let me keep crawling in there for what size it is. 😂 think I saw 9/16 basically 14mm as socket was spun around .

Crazy. We have same truck. Same problems and also love FSJs. I'm about to replace the fuel pressure regulator and injectors so figured I might as well do the dizzy while I have the intake off.

Done that job on my 96 454 suburban biggest pain in the ass distributer ever and I've replaced many.i found it was a great time for new plenum gaskets and injector seals etc.it is much easier to get at that distributer with the intake out of the way

If you pull the #1 plug and put your finger over the hole while turning the motor over you can feel when youre on the compression stroke. Takes the guessing out of finding TDC

As the longtime owner of a Chevy Silverado I think GM’s decision to stick with the design that placed the distributor in the rear of the engine to be an excellent example of the Big Three’s refusal to improve upon their designs even if it means copying someone else’s design. The Japanese automaker’s explosive growth came from taking many American designed products and implementing improvements where needed. I like my Chevy truck but IMO the best thing GM ever did was ditch the 305, 350 platform and replace them with the LS based platform.

Finally a video I have the same isue

I bought a 99 k3500 crew cab with the 7.4 and I'm chasing my tail with trying to solve issues with this engine. The previous owner did replace the distributor and it still would run worth a crap. So I got the truck and I pulled the distributor to inspect it and it looked fine. I have another distributor just in case but I did re time the truck and it ran half way decent for a little bit but then started to run rough and I think I messed it up when I tightened down the hold down bolt for the distributor. so I re adjusted it and I even pulled the driver side valve cover to make sure I'm at TDC, everything was spot on. Now I did remove the mass airflow sensor and clean it. I've replaced all the plugs and regapped them because they were gapped to .060 and some were at .070 so now they're at .050. it still ran a bit rough and I replaced the idle air control sensor and TPS because everything was factory. It did run better and I checked the timing with my timing light and I'm running at 26* of timing. I know a lot of people are saying to be running at about 4* but I don't see that being possible on the vortec but then again this is my first. I did purchase a new ignition coil today that I'll install tomorrow and also I'm pulling the oil pan to check the rod bearings. Now I did notice the passenger side knock sensor was broken and not even hooked up so I'm wondering if that is messing with the engine running and idling smoothly but I just read about 14 pages on a forum of a guy chasing a issue on his k3500 and it ended up being the o2 sensors jacking up his readings into the computer that completely messed up his fuel table on it. Once he changed them out the truck ran great. I'm just not sure what else to check. Also I know it seems like I'm throwing parts at it but in all honesty nothing on this truck has been changed under the hood and it has 164k on it so I figured well I'd be changing all this even if it were running fine just as a precaution. If you have any ideas what else I might check please let me know. It runs rough at idle and seems to not want to stay running for long. thanks

Thanks man, your video helped me out a lot! Awesome to find somebody with the exact same engine as myself.

Monster engine

I have 96 Chevy like yours. Green but mechanical wise the same pretty much. It’s down. I’ve replaced fuel regulator, the coil, ignition module, crank sensor, fuel pump assembly, fuel tank, fuel filter, and now throwing codes for distributor and cam sensor so I’m going to swap those but I’m not to mechanically inclined. Lost me on lineing up before taking distributor off. If you could help me there I’d appreciate the knowledge

So my 99 c2500 Burban just died and had the same issues and symptoms. I’m waiting for my new distributor to ship. I’m thinking my distributor probably wore out at the gear ⚙️ or has loosened up like yours and has lost timing. Once I find TDC Comp stroke, can you adjust timing to 0 degrees by using a TIMING GUNE and the marks on the balancer? Any good advise is greatly appreciated. Thanks

Hey man got a question. Got same year and everything but had to replace lifters. Can't figure out the last plug on the wiring harness. Think you can help me out?

I'm currently chasing a miss on #3 and #4 on my 99 big block in my Suburban. Put in new injectors, new plugs wires cap and rotor and it still didn't fix it. Pulled the upper intake, tested 3 and 4 injectors and they're fine. Now I've got to replace the flexplate and when it gets put back together I'm going to replace the cap with an all brass contact cap, the aluminum contacts in some of the caps can cause cross fire and I'm hoping this fixes my miss. Thanks for the video.

Good video thank you.. I have a 2000 K3500 with the steel rims, tough yes...but I saw your aluminum wheel...very nice...where would you suggest I get a set? Dually in rear..i live in northern California thanks Mike

How do you adjust the timing on these damn things

Trying to get my stupid rotor out and there is a giant bundle of wires or hoses or both, right behind the intake and completely covering the distributor. You don't have that so much but I cant find anything to tell me how delicately I need to treat that particular mess/wall of plastic. Any ideas or suggestions?

Hey I have a 98 3500 n I've put everything new but someone took the colors on my plugs for the engine ECU can u help me I need to know were they go back

Hey ive put everything everything but I have no power on my coil 3 wires 1 only has power the other 2 dont
