4.3L question

TXGREEK · October 22, 2020

Was that motor the Ecotec3 Gen 5 or an earlier 'iron' 4.3? My father has run those iron motors to over 3/4 million miles.

Early nineties motor. Always seemed to me the motor wanted to jump out of the truck lol. Today’s motors, with all the stringent EPA crap is a much different truck.

Damn his dad must be 150 years old or drives 100K miles a year. All the vehicles he’s driven a million miles.

All they really share is being the same displacement and bore spacing. Guys use to run 7 pounds of turbo boost the get the same power as the Gen 5 4.3. They were durable however in any configuration. I love that motor. Later models had balance shafts that helped with that odd idle twitch they had.

For me, jury is still out on the EPA crap and reliability. These motors would not be about to make the power they do without that crap. GDI first and foremost. VVT keeps the torque flat and useful. Together they make it economical to run. I, personally, like AFM. Ever see a Gen 3 4.3 get 30 mpg? Low 20's maybe and then, only if I'm driving

The strong survive and shall inherit the road, the weak shall run its time. Some of those older models were passed down, a lot lol. Though today’s motors are much more advanced, more so to appease the EPA, you couldn’t and wouldn’t say that with today’s motors.
I’ve witnessed Large recalls, seems to be happening throughout all the manufacturers as their rush to beat each other only seals their fate. New vehicles are coming out, EV tech, Ford Bronco is about to unveil their new 0-100 in low 3’s. I’ve seriously been thinking of getting into an EV and shipping it overseas as they’re not very expensive but being fuel is close to $10 a gallon lol. Funny thing, imagine running low battery, how would you fill up, wait 3 hours on a road trip, switch battery packs like my EGO Lawn equipment lol!

I’m still amazed, each and every time I’m overseas as to just how reliable some of those older 4 cylinders really are. New cars, disposable. I’m debating at buying an EV for overseas but reluctant due to servicing as I shipped a new 4Runner to my brother and it took him a month to have something replaced. Petrol is VERY slowly being phased out, especially if Biden wins (never going to happen) as California has said next 10 years only EV’s will be allowed to be sold in California LMAO! I’m thinking of getting into that racket, just outside their jurisdiction, sell anything and everything fuel related.

Well ain't he all that. I've made no secret about these vehicles. Two were Uncle Garry's. One Uncle Bob. Two my father. Three or four my step-sister and her husband who dad buys and maintains cars for as they are sign language translators for the church and travel the entire Western world in that work and do not get paid to do it. He is 93 now and yes, he's been known to knock off 100K in a year. He's a generous guy. Been know to buy cars for people who have nothing and pay their insurance and do their maintenance with the expectation he gets the car back when they are done with it.

As many times as I've made this note he insist dad drove all the miles.

What sort of guy would attack such a man?

Well you decide.

One thing is for certain with the six shooter....They are tougher than a $3.00 steak.

I’ve read the 4.3 is becoming the go to most reliable along with the reputation of the 6.0 and 5.7. We’ll see if cylinder deactivation effects that. Electric vehicles have been on my radar for awhile as a second vehicle. I’ve been converting my lawn equipment to electric for years. Weed eaters and hedge trimmers first. A mini push mower. The next riding mower if the price isn’t too outrageous.

I don't have an EV (yet) but there is definitely a different level of planning required for long journeys. My new cell phone and "newish" Milwaukee power tools remind me of how rapidly battery technology changes. With minimal planning, I haven't t missed a call because of a dead phone or grabbed an uncharged drill out of my tool chest for many years Most appreciate that range/charge considerations will only continue to get better. The length of charge time I believe is an argument that has lost momentum. I know the speed of our progression to EV's can be partially influenced locally by voting but it will happen. I'm quite excited about reducing and eliminating my need for gas station fill ups.

My, my. I attack no one. That’s your territory. That was kidding with some fact to it. I thought I was in your box. Funny though you have mention many times different vehicles he’s put a million miles on. I just was pointing that out. I’m sure he’s a wonderful person. He’s not the one who made such claims.

The TBI 4.3 in my S10 was bulletproof. The CPI 4.3s are the only ones I consider total junk. We couldn’t keep our Blazer on the road once the “spider” started acting up. And that nice balance shaft does nothing when the thing is misfiring like crazy. Sort of ruined the image of the 4.3 for me, although I know the current one has nothing in common and has been a great engine.

Donstar · October 22, 2020

I am glad to see that it is still available and wish GM would continue to enhance this engine and offer it in all models. Ford had an inline 4.9 6 cyl that was popular in all of their trucks for decades. I owned several. It was also found in their 1 tons! Op's engine has two and a half times the horsepower of the old ford and gets double the mpg's. (guessing) I currently own a truck with a 4.3 Ecotec and wouldn't hesitate to get it again!

I’m somewhat retired at 50[emoji6], have excellent vehicles with zero issues (excluding warranty work) and to this day I’ve never driven a straight path to anyone of my road trip destinations. I’m not one that follows, I lead my own way. That said, planning ahead makes all the difference except, hauling an extra two 5 gallon jugs is a “no can do” when in an EV and it’s a lot easier to find a gas station than it is to find a plug out in the middle of nowhere. As for gas stations, We’ve got 3 in the shell stations family, all with open bays (repairs) and I can guarantee you that there’s ZERO changes going on and if so, the oil companies would be responsible to fork over the funds for renovating which I don’t see that happening AT ALL especially considering the enormous loss for them. Oil will NEVER not be used, the US military has been stocking up trillions of gallons, EV is not a reliable source for military transportation as they’ve all failed under their stringent testing.

I think inner cities should get into them but reality is that it’s just the beginning and in the long run, it’s going to cost the American tax payer much more building an EV than it would our current vehicles all due to lead, acids, proper disposal and everything else it takes to build, maintain battery operated machines which I’ve seen nothing but video introduction and major problems with EV’s, so far from, even the leading innovator “Tesla” has had serious electronic malfunctions to even fires [emoji91] and deaths.

Recent trip to an island in the Mediterranean, I was amazed at the lack of care for technology, people were living way beyond the standards, enjoying the simple things in life. I sure miss those large sweet red figs that I’d stop on the side of the road, pick a couple and be full. It’s something I hope everyone can one day experience as it’s the simple things in life that bring out the best of us.

Ok, sorry to go off track....

Boys boys boys, I’ll leave you all with this, “life is short” make the best of it. When served lemons, make great “real” lemonade.
