my buddy(not mine i retired my 4.3 almost a decade ago lol) has a 4.3 in a ECSB and its sort of a dog(obviously) and i'm trying to research some cheap ways to get a little extra out of it, its not a long term truck and not wanting to throw thousands at it..

A 4.3 is never going to make enough power for a fullsize truck.

 

The only thing you can really do, is give it a better mechanical advantage. What gears are in the truck now?

buy a 5.3. I never understood the 4.3. A friend has a 4.3 and always rags on me for having a bigger motor and says there is no need for it. All I have to say is its a truck and I bought it because its a truck, I need a truck for work, and Im going to use it like a truck. He works in a cubicle and has never hauled a single thing in the bed.

+1

Gears are where its at for the 4.3L. Get a set of 4.10's in there and watch the gas gauge fly.

 

Tune and gears man...That's all I would do to it....everything else is a waste of money on that motor.

 

 

Although.....probably the cheapest thing he can do is trade it in for a V8 truck, If you haven't noticed, GMT-800's are not exactly expensive.

Try adding a B&M Torque Converter, Traveler Series to your truck. I added one of those to my V-6 C1500 and it made a noticeable difference. However, if your looking for your V6 truck to put you in a head lock, you'll need to go well beyond that. My suggestion, use the truck as a truck, and purchase another vehicle for the speed. That is what I did. :dunno:

Our company truck ecsb has the 4.3 in it. Does its job for use, hauls more than its fair share in the bed but never tows. We have had 5000# in the bed! So far the leak link has been the 4L60, not the 4.3, however its a dog.

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, the key seems to be with the half tons that if it has the Z71, then it definitely has the two speed. What got me was that the two speed AND the lower geared towing package option could not be chosen together the last few years unless it was mated up to the 6.2. Want the 3.0 duramax and 3.73 tow gears ... nope, can't get the two speed transfer case ( neighbor son realized that after he had bought his used 3.0 half ton .. where the frick is the low range ? ! ).    I am still unsure which truck series, the half ton or the HD truck that the original poster is referring to for sure other than yes his question is in the HD section of this forum but that doesn't guarantee the question got asked in the right section.
