The intake gaskets will fail quick. Mine didn't last 1500 miles before having to be replaced.

The truck runs so much better after the delete. I took my time to make sure everything was cleaned and correctly torqued and used plenty of assembly lube. I did however decide to go with a standard oil pump rather than keeping the high volume. This is to keep the fuel economy and to prevent bearing and seal failure from unused extra pressure. I used a predator 2 tuner to delete the dod in the computer and added a mild 87 octane performance tune. Everything is butter smooth and better than new! Overall I enjoyed doing the work with my sons and AMS delivered with their product and will highly recommend it!!!

Everything worked good. Except the lower intake gaskets (intake to heads) were not the clip on style. Very hard to work with.

One roller lifter out of the pack found to be extremely miss machined due to quality attention, disrupted deadline over a week.

I had issues in my 08 Tahoe with the 5.3, misfire on cylinder 7 to be exact. A shop said 99% a stuck lifter. They suggested this kit so I did it myself. I deliver boxes for a living but have 17 years of construction background and do all my mechanic work myself. I also went ahead and upgraded the oil pump. For starters it's a lot of work and by far the most in depth repair I've ever attempted. It took me about a month of a little time here and there. I suggest watching lots of YouTube and trying to figure out everything else you'll need in advance. I bought this, a tuner, and some miscellaneous tools I didn't already have. I'm in for about $1200 total vs 4k to 5k the shop told me. They said they typically just replace the engine. This kit send like very high quality parts and everything is packaged very well. The only complaint I have is nothing is labeled. Most of it is self explanatory but there could be some type of description on the small things, specifically o-rings. The only thing I wish I would have done differently is order from the company's website because they offer different cam setups, too late now. I got it all back together and had to replace the plugs a second time because apparently by engine doesn't like NGK plugs. After that is running great and no check engine light. Keep in mind you will have to tune it after installing this.

Lasted 1400 miles. Now I have a bad lifter. Shop says it damaged the new cam. Metal through out engine now needs a total rebuild. Save your money for quality parts

Kit had everything I needed to complete my AFM deletion. Not being a mechanic, I was unaware that I needed to tune my ECM afterwards due to the new non-afm cam shaft being installed which makes sense afterwards. Locally it cost an additional $300 due to buying license and an hour reprogramming the computer. When I had completed the mechanical side, I fired the engine and ran like a charm, but when I drove it, it had no power. I ended up having tuner turn off the AFM and tune to the new cam. Doing this brought life back into my truck. If you don't have an issue and want to turn off the AFM just buy the plug in OBD-II connector, but if you have a collapsed lifter and want to delete the afm altogether then buy this kit with new cam and expect to need to tune your ECM. We ended up replacing the oil pump, cam sprocket, crank sprocket, timing chain, timing chain dampener, and oil pan gasket which weren't included in kit (pick up tube seal was) but should be replaced since you are that deep into the engine removing the cam. We had to have the heads redone due to what we found while when tearing apart which was cylinder 6 valves not sealing (Cylinder 6 was the original issue). Kit includes valve stem seals. Highly recommended doing that as well since you already have it apart. The heads being rebuilt was an additional cost, locally it was 500 for both heads being rebuilt and compression tested. Altogether with additional parts, heads rebuilt, new fluids and tuned it was about $1600 and 30 hours worth of work, but again I would not say I am a mechanic but mechanically inclined. Local shop said they could do it for $2500, but didn't include heads being rebuilt and extra parts. So I was looking at $3000 plus. I hope this helps someone else who is trying to decide which route to go and how much it will cost. The work was completed on a 2008 Chevy Suburban 5.3L
