Absolutely turn this into a project! More V6 and Straight-6 projects would be awesome to see!
Yes, hate to see the old inline 6's go by the wayside, they were the most foolproof & reliable.
I'm excited to see a 4.3 build!
Yes. Looks at my 02 xtreme blazer would like to build a 4.3 for it to make more power not looking for crazy numbers but would like 200-250ish range.. My old 92 s10 is eventually getting a 6.0 swap
Yea, if you google it its a bunch of nay sayers. I'm like Yes! Let's see it!
@@christophersmallwood3944 David Freiburger did a good write up on a 4.3 build. I wouldn't mind building a Vortec 262 for a S10..
I like the idea of turbos like a eco boost
@@Jihadbearzwithgunz nice car I love it. I have too camaro but I need also race track like this
I really hope you guys keep this trend of odd builds going. I’d love to see a 3800 supercharged build
Noooooo. Then our special cars will be more main stream and more expensive to buy lol
Richard Holdner channel has a recent 3800 build with different super chargers/turbos..
👀 3800!! Yesss
I would to see this as well. I've had 3 Oldsmobile 88 Royale, '92, '93, '97 They all had the bulletproof 3800
Love the 6 bangers no matter which way they point, yes please on the 4.3 build
Love that more than half the episode becomes a infomercial....
I thought the same thing. But, these builds are expensive. They gotta please the sponsors.
You guys should do a GM 3800 V6 build for a Pontiac Grand prix or something a long those lines would very much appreciate it
No aftermarket...
I agree
@@ComputerCapone There's an aftermarket, heads, cams, etc. Just nowhere near as big as some other engines
That would be awesome. Considering how reliable the 3800 series 2/3 blocks are. Richard Holdener is in process of doing a "Big Bang" test on the 3800. This is where he takes a junkyard motor, puts some ring gap in it, upgrades the springs and using different cams to see how much power the 3800 can handle. He'll also put head studs in. Subscribe to his channel. It would still be nice for these guys to do it, because they have a lot more resources and they could build the engine with forged pistons and rods. There is also a billet crank and main caps available for high rpm/boost applications. Along with aluminum heads.

I'd love to see it as a crazy NA build: methanol burning, tall intake, wicked cam
I would really love to see this turn into a higher compression (9.5:1-10.0:1), twin-turbo, higher displacement, fuel injected (without that asinine spider injection system that my Vortec 4.3 had) EcoBoost clone to see how much more power it is capable of making while still keeping it within safe levels. I really think that'd be a cool project to see. Then y'all can swap it into a cool S-10 Xtreme and make a road course truck.
Like your gonna find an extreme thoughs are rare.
Just while your dreaming, start with a GMC Cyclone!
Would be better in a 1st gen. They're a lot lighter, and all the zq8 suspension pieces will bolt right on.
Great idea all the way around.
@@arytonbreet7671 Thoughs?
Absolutely loved that you guys are going to feature this engine. Unfortunately in Brazil we don't have easy access to V8s of any make (at least not in my budget range) but the GM 4.3L Vortec V6 and the Ford Cologne 4.0 V6 are somewhat accessible. I know you Americans love your carburetors, after all they do look nice and sound great, but I would hope you guys make this a Fuel Injected engine, preferably port injected (there's a 2003 model version of the 4.3 that doesn't use the spider style injectors) and LS Style Coil on plug for that nice "modern" look. Maybe a Syclone/Typhoon tribute engine for all turbo Junkies out here? Or just an everyman affordable build?
I never thought I would see you all build that engine. I always thought the 4.3 had a ton of potential because of the similarities it has with the 350. My 2006 short bed chevy has that same motor in it. I have often considered building it. I can't wait to see what you all do. As I understand it those little things actually have a strong bottom end and with a few tweeks like splayed main caps and hardened crank it can handle some power. The only issue's i saw was getting the air and fuel to feed it with limited after market support for that particular motor. I caught you mention the rods were 5.7" i think. I always wondered if you could or should swap those out for some 6" rods? What would the result be? Anyways, can't wait to see where this goes!
You have what is known as the LU3 262 Vortec 4300, it is better than the L35 which was around during the L31 350 Vortec.
Your cam lift and duration needs to be monitored. This is a 75% 350.
Rods are not the same as a 350. The pistons are. The 4.3 rods have a bigger big end, and the rods are narrower. All of this is because of the split pin crank in the 4.3.
To feed the air/fuel I'm using an Edelbrock intake modified with 42# injectors and a Holley Terminator X ECU.
I'd love to see a project of this engine, I'm currently working on the same engine myself!
Mild street engine on a budget is a popular build style for a 4.3. Something an average workin' man can afford, then donate some rubber on the weekend.
L35 or LU3?
It's a 350 minus 2 easy to find parts for everywhere..
Awesome
Matco tools
Great video
Lots of info for the hobbyists to the pros
So cute to see Frankie mopping the floor. It gives him a human side one can relate to, and his response is really cool. Thank you kindly for leaving that in.
Nice I just bought a 95 v6 5peed manual. my idea was to put a 350 with the fitech fuel injection and put a automatic transmission but with this I might just fix the v6 and I will done faster keep up the good and very informative job 👏
It’s about time! There are a lot of 4.3’s out there. They are a compact powerhouse.
My boss built an adapter to mount a small roots supercharger plus modified the supercharger snout (shortened it) in order to use the supplied drive system from a SBC kit on a 4.3 Vortec. Made around 380 HP on pump gas, went into a ski boat.
Very happy you are doing this engine and can't wait to see what you do
Take a note from the guys of Roadkill! Turbo it and stuff it in an old Datsun. Just do it well enough so nothing breaks!!
Ring gap, mls gaskets are key
Thank you for this Episode 👍🤗
Id love to see the 4.3 rebuild.
I LOVE IT!!!! GREAT 4.3 REBUILD!!!! THANKS FOR SHARING!!!! SO MUCH FUN!!!!
The guys work great together!
Guys - when are you going to get back on this build? This is by far the most interesting ones!
I think this is going to be interesting for me because I did a stock rebuild of this exact engine for my 1997 s10. Can’t wait to see what you guys do with it, it’ll give me ideas for the future!
This is soo awesome I’ve been looking for a good 4.3 video makes me keep that engine
I've heard that song before; "39.5 in the hole!" 😆 🤣 😂
wow. great timing here. my 87 elco has a 200,000 + mile V6 that needs a rebuild.. this is PERFECT!
I had this engine in a work truck and I loved it. At 110,000 the water pump let loose and I decided to change the timing chain while I was at it. Dumb move because till that date I had never timed it. I use Restore in all my oil changes and the result for this engine was that I did a compression test at the same time and the lowest psi was 185. When the truck went back on the road it had more power than when new. A month later the lower end let loose and I had to rebuild. Long story short, the same shop that services the Gator Nationals boys, right there in Gainesville FL, bored it out 30 over and put stock parts back in, that engine found crazy torque and a lot more HP. Great motor and BTW the shop said you could bore it out to 90. Have fun boys!!!
This build is right up there with the 300 Ford six. Looking forward to see which direction you take. I’ve seen a couple of these used in rear engine dragsters, they were very impressive. I’ve always wanted to put one of these in a Older Jeep or mid engine sand rail.
You guys should do a 2.8 v6 out of an s10 one time, I would love to see that
Dual overhead cams, 4/71 blower, rollers, injected, a mini LS engine in the back of a VW! ZOOOOOOOMMMMM!
Great video, must be having lots of great coincidences because we just recently bought an old hyster forklift which runs a 4.3 GM v6 and now there is this video.
Great video...lots of very useful info!
I really like Matco tools I got a 1/4 ratchet and I’ve put all my weight into it to break a bolt lose and it holds up nicely love the quality tools
Made by AJ Manufacturing for Matco,this is with the Matco ratchets
I'm glad I found this video. Th 4.3 V6 is a reliable engine. I want to see this engine build
YESS I’ve been needing a video like this. Edit: never mind half the video is a commercial
Thanks! For this. Would yall consider a comparison of the various 4.3 v6? Also aftermarket items for these engines?
Project with the Atlas 4.2L inline 6...please. Especially if you are going to start showing off more historically underrated domestic six cylinder engines.
First Trailblazer we sold at the dealership I worked at came back a week later with a dropped piston sleeve. We all thought, great this is going to be a piece of crap. Well, we got the one bad one. Those were great engines! The 4 cylinder was great too. For some reason, the 5 cylinders had problems with rusty camshafts and valve seats were too soft. I don't understand how the 6 and 4 were so good and the 5 was bad.
Soooooo stoked for this. Race truck is getting an all aluminum gen I bowtie 4.3 and the street truck is getting an LV1/LV3 gen V 4.3, always have and always will love GMs big V6
Back in the early 90's I had a LTD 2 with the first of the 3.8 Ford V6. The heads on that engine looked just like Cleveland heads, other than being cast in aluminum. I cleaned up the casting on the 2bbl intake and heads put a 500 Holley 2bbl carb on it and that little sedan would give mustangs and camaros fits. That was a very fun car.
That "entry level" Matco 2s toolbox is $4,200 💀
The color options are worth it 😁😁😁
Really not much more from 25yrs ago..
Please do this as a full build. I've been waiting for a v6 for so long
On that 4.3 you could do cam, Springs, rockers, coil on plug conversion, and custom intake, then send it to me😜👍.
Who makes a coil on plug conversion for this engine?
@@kevinhornbuckle look for a sbc v8 24x efi conversion. Then get 6 ls style coils and a 411 pcm. It works.
@@kevinhornbuckle also I think 2001 and up s10 use 411 pcm so the harness for the v6 is perfect. No need to repin...😜👍
Cool motors and they are everywhere!!!
I have 4.0 mustang daily driver, thinking about doing minor upgrades . Cool to learn from this video and all videos
Always enjoy!!!!!!!!!!!!!!!!!
One of the best power plants made. I had a GMC 1500 WT with the 4.6l and sold it with 380k miles on it. The truck was falling apart (literally) and the new owner bought it just for the motor. He put it in his boat after rebuilding. He told me that the cylinder bores still had the factory cross hatch. Strong motor.
Thanks again for all your work!! I think that the engine community would love to see a supercharged 650 Hp 6 Cyl engine for road racing!! A engine that would fit in many platforms and be affordable!!!!!!!!!
A pro charger ,or a vortec supercharger for a 350 small block will bolt right on. That's what they should do with it. I think you should be able to run about 9 to 10 pounds of boost with out o-ringing the block or heads. Put a bigger cam, and a set of long tube headers. I'm just offering some ideas for you guys.
very very nice!
My guy selling the ratchets is a Tier 1 Seller lmao
I love my two 4.3 s the 90 manual gets 20 mph on highway and has 400000 m on her and starts first spin and is a great truck my 04 my grandpas old truck has 100000 and runs great too both were familys previous the 90 was my uncle’s great to keep all the old classics of the family
I love the V6 platform. I'd like to see one built out with a blower
The one in my 94 S-10 standard cab long bed is still running strong .
It’s crazy to say it took this long to do a build like this on tv. It would be nice to see the cylinder bore to a 350 made into a echo boost motor.
Me too! I have a 99 S10 with the V6 in it! I can do a few improvements to it if I want.
I’m still Waitn for the nxt episode for this v6 build 😂
I can tell you the biggest thing to being a successful Matco dealer - showing up!! My Matco dealer has been a no-show for years now .
4.3 build I'm all in!!! Build that beast, so I can build mine. My 92' Sonoma GT, that I've for 30yrs. Old GM never die they just run faster!!!!! I wish I know you guys were building one you could have used mine!!!
Richard Holdener here on TH-cam stuck a Torquestorm supercharger on a balance shaft 4.3 and it made stupid power. Granted he put a carb setup on it to make it work on the dyno.
Thanks for all the great content guys, how about an engine build for slow technical trail driving or rock crawling, very low rpm torque, smooth delivery with power when you need it, I'm sure there is an audience for this type of build
I have a 96 S-10 blazer 4x4 and this has me inspired, thank you. 5.7L pistons huh? Obviously gonna need a different cam.
GM Vortec 3000/ 181ci high performance build. Love to see a buildup of this forklift and marine industrial engine based on the Nova 4 cylinder of the 60s. Great engine for a lightweight rod
Can some explain why on top of the exhaust valve spring is a bigger ring and on top of the intake valve spring there is not? I recently bought a set of heads (3890462) and and 1 head has that an 1 does'nt
Nice!!
I've seriously been thinking about putting a 4.3 in my '48 Willys CJ2a and shelving the L134 it currently has in it.
👀 I'm still waiting to see the rest of this build!!!
Love it. Slap a couple of turbos on this puppy. Too bad Chevy didn't follow the design of the Buick 3800 and design the block with a deeper skirt and have cross-bolted main caps.
3800 came after the 4.3
@@bepbep7418 So. Chevy could've still followed what the 3800 series 2 didn't in 95 as the 4.3L was in production for years after 95. With the latest 4.3L, it is designed after the latest LT.
@@bepbep7418 When did the 4.3L get a balance shaft? What year? 88 was first year for the pre-series 1 3800.
@@charleslowe522 92 is when GM redesigned the 4.3 to take a balance shaft. They're both 90° V6's. Both have their pro's and cons. A BIG con (IMO) of the 3800 isn't the motor, but the trans that it's bolted to. The 4T65E is a pig of a trans.
4.3 v6 are monsters!even in stock form
These engines are capable of a lot
Nice start. Love your show. Be waiting for this for a life time. My 1987 S10 Blazer bought new always garage kept has always cryed out for an upgrade to a 4.3 super charged. Whipple Auto rotor Opcon supercharger kits from late 90 are to rare but would be very cool. Twin turbo would be cool as well. Don't for get about manual trans behind. Love to row the gears. Here is my shameless plug, if you need a platform to put it in..... Cant wait to see what you guys come up with.
Please do this as a twin turbo set up. I've been wanting to do a twin turbo 4.3 in my S10 for a while and would love to know just how well the stock block can survive the abuse. Otherwise I'm stuck looking for a bowtie block, an aftermarket one from a machine shop near me, or an old Nascar 4.3...
Would really like to see what intakes and heads are out there for this. From what I've researched, it's pretty much either crazy expensive heads (circle track by Brodix, I think) or hog out the stockers which flow way better than stock but are still weak. I'm not sure if anyone even makes and intake for it other than sheet metal ones. I thought Eldebrock made a carb intake for it at one time. Maybe they still do.
I'm actually getting ready to do a 4.3 build . Would be nice to see how much power you can make n/a
Man, I would ship my truck to these guys if it means I'll get the same care.
An awesome turbo blow threw carb build would be sick and do some extensive internal break down on the carb setup
Go crazy with it: lysholm supercharger, twin turbos and agressive cam for crazy power!
Where can I get the 350 bore plate? Who sells it?
I have the perfect project for this engine. A 81’ AMC Eagle SX/4 Sport Limited. It now has the Pontiac 2.5. I am pretty sure it will bolt up to the 4-speed trans
Great idea. I had a new 82 Eagle Sport with an automatic. The car was a blast but not enough power to spin a wheel even in snow, it would just GO. I have also had several of the 4.3's and loved them and always wanted to build one of them up but never thought of putting one in an Eagle. It would be interesting combo if the drive train will handle it. I had a pretty dark blue Eagle with gold stripes. It would go anywhere in rocker deep snow and also in the loose sand at Daytona, never had it off road in any deep mud, it was too nice to take a chance of messing up the body. The only 4X4 that I know of that came from the factory with white side wall tires! I think of that car every time we get a deep snow. Like many other cars I wish I still had it. I do still have a couple stock 4.3's, the best one being the 95 model vortex with the spider injection. The only trouble I've had with them is distributor caps and rotors.
Crazy, I was just thinking yesterday they should do a 4.3,,,lol
Did they ever do a update on this ?
With 1M subscribers must be time to pay the guys for commenting back on Friday afternoons lolz
Im only 29! Haha cheers guys
I would love to see this become some high rpm screamer twin turbo project
A 4.3 v6 would be very hard pressed to reliably spin past 7k more than once... but with an unlimited budget anything is possible.
@@Kstang09 I mean I saw this guy build a pushrod v8 that reved to 10k for his camaro. Surely for a v6 it has to be possible
@@maximebeaudoin4013 Do you know why these v6's come with a balance shaft? Look into harmonics + resonance and how that affects RPM capabilities. Ditto valve train stability + intake design. (short summary, this particular engine is very hampered in that department).
Also, curious what makes you think that because a pushrod V8 can be built to rev a V6 inherently can as well... does fewer pistons amount to more RPM in your mind? Like I said, with unlimited budget anything is possible. Just best not to use a 4.3 v6 as your starting point.
@@Kstang09 nah man just got to source some a.r.c.a series parts they ran 550hp 4.3 naturally aspirated engines that were built to run up high around 7500rpm
vortec 2700,2900,3500 and 3700 are also great cheap GM drivetrains with tons of potential. the inline 4 and inline 5 design makes them quite capable especially with boost. or the SAAB B207R or ecotec LNF or LDK.
I would love to see what a 4.3 can make I have a 1991 GMC Jimmy that I'm planning on popping up
I have seen motor builds on different engines lately. I have a Buick Regal T-type Limited, it has 200,000 miles and going to do a build for it. You have done a 455, a 350 buick. AMC, chevy and ford 6 cylinder engines. This is a Chevy v6. Being that a Buick Grand National is iconic Muscle car, it seems that a Buick Turbo V6 would be a interesting project.
I need that thread chasing kit.
About time some one did these builds. Same old V8s every time gets old
It's going to be extremely lame if y'all don't do a 4.3 build
What exactly is this engine out of?
It's alot like the aussie/gm l36 3.8 ecotec
I think an S10
They came in the chevy s10 and gmc Sonoma as the upgrade from the base 4 cylinder. They also came in full size base model pickups that were work truck designated. Really versatile engine.
They were base engine in full-size 1/2-ton pick-ups and vans, only engine in compact rear-/all-wheel drive vans and top engine in compact rear- & 4-wheel drive pick-ups. Older versions were available/standard in various GM rear drive passenger cars.
Down here in Australia we have the Buick Ecotec v6 engines. They look very similar to this bullet, other than they have cross bolted mains, and rockers on a needle rollers.
L35 Vortec 4300 262

Been looking at a 4.3 for my 81 Honda Civic wagon
I would like to put a turbo blower in a 3900 and a Chevy Impala about an 0509 or whatever but figuring out where to put it different but I would love to see you guys try to do that
I have a1987 Chevrolet Custom Deluxe truck that came with a 4.3 V6 TBI ! Would like to rebuild it! Think you guys could do a video to rebuild it! Would really help me out! Love the info you provide for everyone! Hail to the gearheads! Rock on!
Wow; that’s a lot of explanation points.
I recently did the head gasket on my Datsun Bluebird engine. It's a 1.8 gasoline engine, known as an L18. I put two head gaskets would that change the displacement?
How would it?
@@Icutmetal I was thinking the extra thickness of the second gasket?
@@MerlinOpeth Right, but how is that going to change displacement, which is tied to the bore & stroke?
@@Icutmetal I'm not a mechanic so obviously I'm wrong from your reaction. I'm just thinking that would be extra cc's in the combustion chamber.
I always liked the 4.3 and glad to see it get some attention. More please! Guys, I really like this show and the hosts... but for god sakes calling an engine a 'bullet' so friggin stupid.
Along with this engine I wanna see some V10s come into the shop for some big power mods
More 4.3 content!!!
I recently bought a 1997 C1500 SWB pickup with a 4.3/5 speed. I'd like to get a bit more power out of it for little money. I understand that replacing the mechanical fan with electric ones can free up about 20 HP.
Nice I just bought a 95 v6 5peed manual. my idea was to put a 350 with the fitech fuel injection and put a automatic transmission but with this I might just fix the v6 and I will done faster
@@ferberb9662 Keep the 5-speed!
@@ferberb9662 A Fitech EFI system would be ideal for this platform, especially if you modify the engine for more power.
Yes it would be awesome a good daily drivable and reliable truck to put miles on it. it would be excellent now if you put a turbo you might scare some eco boost not to win but to just stay behind
