    Gen 4 engine builders out there...walk me though me first build.

    Questions for you guys that have done DOD deletes. This motor is an L9H going into a 2007 l92 that has the DOD equipment but not tuned into the ECM. The camshaft part number for the l92 has been superseded by the l9h and my understanding they have the same specs. However when I look up the cam...

    Gen 4 engine builders out there...walk me though me first build.

    Yep I feel very lucky I happened to watch that video. The machine shop said, according to the Dura bond tech, the GM gen 4 and gen 5 aluminum blocks are the only family of motors they offer undersized cam bearings from .001 to .003. So this issue is specific to these aluminum block LS motos so...

    Gen 4 engine builders out there...walk me though me first build.

    Yep had a little hiccup. This is a big deal and something to know if your building one of these engines When I tore this thing down the cam was in there nice and tight. When I installed the same cam into the new Durabond HP bearings, I thought "well that seemed a little too easy. I have built...

    Gen 4 engine builders out there...walk me though me first build.

    Sounds like you have a guy like my old machinist. I called him up after 20 years and he has retired and only does head porting for the racinb guys now, I'm in California, land of Tesla's and government that hates small businesses so our machine shops are drying up fast..... This guy was young...

    Gen 4 engine builders out there...walk me though me first build.

    Hi thanks for the reply. Mine is alum block and I did not specify but this is stock rebuild. I can see from my post that could be confusing. Looking at your profile pic, are these clearances that you use for race stuff? Everything I have, from mulitple sources show factory specs at .0008-.021...

    Gen 4 engine builders out there...walk me though me first build.

    So now lets talk main bearings.....Of all the low oil pressure posts, threads, and videos i've looked at this video is the one that made the most sense in my engine builder brain.... . If you don't want to watch the video, he mixes standard and .001 over bearings to get oil clearance of .001...

    Gen 4 engine builders out there...walk me though me first build.

    This is the continuation of my "life is like a box of chocolates" thread from back in June. Got sidetracked with a pasture fencing project and the overall business of having a newborn son. But I have to get this done and on the road before it starts snowing so the engine is back at the top of...

    Transmission issues... lots of questions

    If your towing with a 6l80 big cooler is a must IMHO. I know the earlier trucks (I have a 2000 Silverado) had a driveline clunk that was quite common. Mine has it have not done anything to it 215K and I abuse the shit out of it. 2007 Yukon Denali the D/s front diff mount went out. I felt it by...

    2007 Yukon 6.2 stalls/won’t start when hot

    Sorry I havn't had time to read this whole thread. But are you sure its fuel and not ignition? Our truck did the exact same thing you are describing. After two tows and starting up the next day, throwing some parts at it, and wanting to blow it up, it turned out to be the ignition switch...

    Life is like a box of chocolates....L9h engine

    Could be......well never know though. Affirmative on Fel=pro they have always done me right and when I did the oil pump on my rig, I immediately saw the improvments fel-pro made on the oil pan gasket. I got a set of head gaskets from Brian Tooley and Mahle exhaust gaskets but everything else is...

    Life is like a box of chocolates....L9h engine

    Went to the machine shop Friday. Never used them before but my machinist retired and only does head porting for racing guys now. Young guy spent about 45 minutes listening to the history of the motor from CARFAX what I intended to do with it and budget concerns. He did say the dots and paint...

    Life is like a box of chocolates....L9h engine

    I would do that if I was doing the install. But I’m paying a shop to do it. It’s going to the machine shop because I have never installed cam bearings let alone in an aluminum block. I have heard these can be difficult so not gonna make this my first attempt. I may home the block cuz I’ve done...

    Life is like a box of chocolates....L9h engine

    So I have it completely torn down to bare block. Three or four pistons have scoring you can catch with a fingernail with number one being the worst. The one/two rod journals have a small line you can catch and same with number one main. Visible cross hatches in all cylinders but number one is a...

    Life is like a box of chocolates....L9h engine

    It looks good to me. Lifters look good only one has a slight suspicious wear mark on the very outside of the roller. I’ll see what the machine shop says. As far as I know the only way to know for sure is to assemble and put a degree wheel on it?

    Life is like a box of chocolates....L9h engine

    Ok thanks good to know. Out of curiosity how can you tell is it the 7373? Why don’t they just stamp the full part number?

    Life is like a box of chocolates....L9h engine

    Yeah what a nightmare that would have been if I had installed it and its not the right cam. That would have been the absolute last thing I would have thought of.

    Life is like a box of chocolates....L9h engine

    Life is like a box of chocolates....L9h engine

    So now that this engine is suspect of being a Frankenstein how do I ID this cam? If it’s been changed or different from the factory installed, I don’t want to have to deal with tuning issues.
