Assembly on the 4.3L engine begins with a solid bottom end, including a set of forged pistons and a bigger cam shaft. Once we install ported cylinder heads, upgraded valve train, and induction…the 4.3L engine shows what it can do in the dyno cell!

Chevy was like hey let’s chop 2 cylinders off and make a kick ass V6
my 4,3 Vortec has almost Reached 250,000Thousand Miles and still Kicking!!
That part where the head studs go into the water jacket. That’s one of the old small blocks weak points. Great engine overall though.
Normally I enjoy the Power Nation vids but this is truly ridiculous. There never was an "old school" way to build a 4.3 because nobody ever built one in the "old days". There's no reason to build one as no race organizations use them and nobody uses them in their cars.
SO THERES A KIT WITH BELL HOUSING YOU PUT THESE SIMPLE 4.3'S IN YOUR 80-90'S TOYOTA 4-RUNNERS AND THE TOYOTA FANS ALL SWEAR THEY ARE SIMPLER CHEAPER ON PARTS AND MAINTENANCE AND HAVE WAY MORE POWER ………..CRAZY COOL!!!
They eventually boosted this engine and got over 500 ft lbs. 😂
I need to rebuild a 03 4.3 vortec.
No need for. V8.
It just burns lots of oil
❤ That you made this video! 👍🇺🇸
Im a ford guy for many reasons, but i dont argue with a sbc ever, solid platforms. This v6 is the best ive ever worked on. Which means i dont work on them, they are that reliable.
More power than my stock 89 C4 on that second pull.
Nice work gentlemen!😅
Wholly Crap! 😮
That torque curve jumps right up and stays flat all the way to 4300!!
Is it old school or is it fuel injected? The two don’t “coexist”.
Fun fact: the 4.3 is just a 350 with the two back cylinders cut off😂
Even the stock 4.3s would incinerate tires on the old S10s. Couldn't imagine what kind of hell you could raise with this. Tires would stand no chance!
There was no disrespect to 3.8l v6, but I never understood why they never used a 4.3l in the Camaro and went 3.8l.
I can tell u my favorite tool 2 use at home sure as crap don't come outta my tool box😱😱😘
The “Great Success” part is so underrated. At 10:05, I laughed so hard I accidentally hit the subscribe button.
how much for the 4.3 yall build
I really enjoyed watching this video on the V6 engine. Looking forward to seeing more content on the V6😊
Well done 👍
The Chrysler 3.6 v6 is already 300hp
I was expecting closer to 300
These sound just like the water ski boats on the lake that I am used to.
I just removed one of these from a 1999 GMC jimmy and but new engine doesn't have a trimming tensioner and the old one does
Any more pens in those pockets people will start to ask questions. You look like dork
Are the engine mounts the position as the 283
Will a 700r bolt up to it.
Does HP just disappear in the US? How do you only get 244 HP from 4.3l ??
I got a 98 Chevy S10 2.2l 2wd 5spd w/ 47k on her y’all can put that in.
Excellent episode 😊
I'm buying a Chevrolet blazer 2002 4 door with the 4.3. I have plans of driving from Connecticut to New Mexico and the engine is knocking and don't trust it that long of a drive. Is there any way you guys could donate a refurbished 4.3 liter so I can go out west for work found a job out there. Keep me in my you guys do tremendous work. I'm buying it for only 900 dollars because that's all I can afford.
