  1. great info! Keep it coming, I really appreciate y'all putting in the time to respond. I'm taking it all in and learning. The more info the better.
  2. I think I may have found info relating to my trucks issues with cold starts and the starter staying engaged. Bulletin No.: 16-NA-383 Date: May-2017 https://static.nhtsa.gov/odi/tsbs/2017/MC-10137635-9999.pdf Hopefully I can do a intake service and fix the problem. Just thought It may help someone else that may be having similar issues. Anyone tried AT-100 intake blast? or should I go with Seafoam fogger? https://www.amazon.com/ATP-Automotive-AT-100-Complete-Fluid_Ounces/dp/B01FFRYF6M/ref=asc_df_B01FFRYF6M/?tag=hyprod-20&linkCode=df0&hvadid=241961652672&hvpos=&hvnetw=g&hvrand=11924419964896152434&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9010894&hvtargid=pla-583835246288&psc=1
  3. Thanks for all the info. This is what I need to know. If I find a 6.0 I need to make sure I get the intake too, correct. \ All other acc from my motor will bolt up. Would I leave my trans as it is. Same torque converter? a I dont want a race car. I just this truck to commute and family vacations But If I'm coming up on time to do timing chain, water pump. may be worth upgrading if its not too much more work.
  4. Thanks for all the info you have provided thus far. I need to start looking at what makes the most since cost wise and what is available. Is the best way to find used motors to just call local junk yards and ask for the specific year model 6.0 that I'm looking for? I'm glad you informed me about the intake manifold being different. I was under the impression that it was all interchangeable.
  5. What would it take to upgrade the trans also? I dislike the 4 speed but that may be more to do with the lack of power in the 4.8L and prob gearing in the crew cab.
  6. So If I were to source a LY6 or L96 to I go for a re-maned block lower end and move over all my top end or junkyard a complete engine? What kind of of gains do think my truck would see going to a 6.0? Is the 4L60e likely to trans I currently have? If it will bolt up to the 6.0 options? If I'm not running big tires or a lift or towing a bunch wouldn't I see a gain or maybe a balance in the current MPG being tht the engine has additional HP and torque
  7. Okay, guys I'm new to all this but after searching the inner webs I'm now really confused. I have a 2010 Sierra Crew Cab SL 2WD 4.8L with about 170,000 miles. I'm the original owner. I know I'm getting up there in miles and will likely need to start doing major maintenance in the near future to keep this truck reliable. It has recently started having terrible cold starts, the starter sticks and the engine misses for like 10-15 set the all is good and the problem is gone on the next startup. (not sure whats going on) I plan to keep this truck running till the wheels fall off. Its paid for and does the job (and looks good). Due to the recent issues I'v been thinking of what my best options are to keep her going long into the future. I mentioned to a buddy what I was thinking about and he brought up replacing the engine with a 6.0L when major issues arise. I like the idea of the additional ponies ans the 4.8 has always been weak, especially paired with the 4 speed trans. My truck is basically bone stock and a daily driver / commuter. I want reliability but some more power would be great too. What are my options for engine swaps? There are so many engine codes and different year models that I'm lost as to what fits with minimal mods. I know I will need to get my ecu tuned to a different size engine but some say the 4.8, 5.3, and 6.0 are interchangeable. but year models and engine codes year models come into play ( then I'm lost). I also have questions about my trans and gearing. Can I keep them ? Will they work? Will an upgrade kill my MPG? I need some info from guys that have experience with this stuff. I'm not trying to build a hot rod just a strong reliable truck.. Thanks for any info you can provide.
