I found a camera video of my Blazer getting the last Dyno session . Sound quality is a little off , this is the 3rd or 4th run after sorting out a lean condition. Nitrous is installed but we didn't use it until we were sure that we had fuel. Now I have fuel !! With the supercharger A 50 shot gave me over a 130 hp! But the torque went through the roof! With out nitrous my torque curve is almost flat, I have since replaced all of my shock absorbers with Belltech Street Peformance shocks. Made a world of difference from the superlift shocks that were on it. I also cleaned my suspension after seeing the pictures that I posted. I will update my Photo album with the latest pictures of what it looks like now. including the nitrous switch panel install and where the progressive controller is mounted.

Thats a really good looking Blazer. What kind of Body kits do you have?
Back on topic, I wanna get mine truely dyno'd I have had the horsepower measured on a handheld thing that plugs into the OBD. That said I had 210bhp @ 3500rpms, but I'm not sure if its accurate. Something made by superchips.

The real problem is that that was a old video. and it was shot on a camera with a video option . The really bad part is that all of the sound of the motor was muffled by the hose on the tailpipe that went out the back of the building. We didn't go for the 6500 rpm that it is capable of but ran it on the dyno only up to 4000 rpm . The great thing about keeping the V6 is that the torque stayed almost flat from about 2500 to 4000rpm. I will find a video that is a lot better that shows how it really sounds with the nitrous on. Music! The HP on the V6 climbs steadily and does'nt leval off but keeps on climbing !! Keep the V6 you can make just about the same HP as the V8. Don't be misled by the people that tell you to put in a V8, look up the HP numbers for the V8 it just might surprise you to see the actual low HP numbers. the V8 in the Blazer SS and the SS Silverado is about 371 HP, I have more. They can get you on the torque but you can have more HP. That is where the nitrous come in. Torque out of a bottle! Nothing is better than a 4000lb 4 door 4x4 Blazer with people in it smoking the best that Ford Gm and the imports have to offer . The nitrous also helps me with the supercharger . Just by using a 50 shot I get much more than 50 HP because it actually cools my intake charge. The supercharger loves it ! My wallet does'nt!!

You have a nice truck, no doubt, but you will never convince me that a blown v6 is better than a n/a v8. I will give you that it is easier (work wise) to put a centrifugal blower or a rear mount turbo on these trucks than it is to drop in a v8, but a v8 has more potential and a much larger aftermarket. You are comparing your modified v6 with a stock v8. Those TBSS trucks are nasty in stock form and rediculously nasty when modified. There are some of the Trailblazer SS trucks that contended for the LSX title this year that were well into 10 sec 1/4 mile runs.
HP is for bragging rights, but torque is what wins races.

How would you feel if you found out that your factory effort V8 SS over 35.000$, was beaten by a homebuilt V6 5,000$ Blazer with about 6,000$ in it ! I think you kind of would be humiliated. What do you think? Any engine can be made to run, all you need is money and time. You are correct that a V8 is a great starting point and can make very good numbers, but a v6 has less rotating mass. And to me was much more satisfying in making it run. There are plenty of 4.3 v6 engines doing way over 500hp and some well above 1000hp . Don't sell the v6 short. they have been talked down about long enough. Most of the bad press comes from the big muffler and air cleaner generation. If i invest an additional 3000$ in my engine I would be a force to be reconned with. V8 Blazers are nice, I am building one. But just how many 2nd gen Blazers v8 are out there ? We have very little room in our newer engine bays ! 1st gen yes ! They have room. we don't. I also want a 6 speed tremec, Might happen might not. It is great to want and wish. But sometimes you just have to face reality. And realize that some things are just that . A wish.

There's quite a few 2nd gen V8's, actually...
A built V6 is nice, but so is a built V8...
It's all personal preference, really...
Cost vs. Gain, depends on what kind of numbers your shooting for.

SS, you have a fundamental flaw in the logic used. You are comparing a 9 year old vehicle with one that is brand new. You are also comparing a top of the line fully loaded machine to your truck. A better comparison would be a '98 or so v8 pickup or Tahoe with the same amount of money into it that you spent (~$11k total if I remember how to add right). I know for a fact that I could pick up a '99 Tahoe 4wd for $6k tomorrow (there's one for sale just down the street). $5k into the drive train (not just engine)! Trust me when I say that $5k into a 5.7L v8 & associated drive train upgrades gets you MUCH further ahead. It is just simple HP gain for your money. Add to the fact that I can do most of the work myself and I could build a blown 5.7L capable of 500+HP motor HP (i.e. no bottle) and upgrade the transmission and diff for that $5k. But then again, you have never stated what your truck is producing only that you've had it dyno'd.
I'm not cutting down the v6 by any means. I used to own a L67 Bonneville (3800 supercharged) and that was one fun car with A LOT of potential. Quite a bit more potential than the 4.3L v6, again simply due to the following & after market. I know what they can do as I have ridden in a 9 second Grand Prix. Dollar for dollar, any v8 will far out perform a v6 simply due to the plethora & cost of after market performance parts.
If your comparison point is on rotating mass... well...
*EDIT*
In looking back through all of the posts that we've had on this topic, I found one thing interesting. You show your blazer up on a dyno, but yet we have seen no numbers as to what it actually put down. You state that you gained 130HP from the spray, but 130HP added to what? What does the motor do after all of the work that you have done to it??? So again, I'll ask what HP/torque is the thing putting to the ground (graph would be nice)? I don't like repeating myself.

Very very nice. I agree with swartlkk on the v8 potential. But I also agree with your viewpoint of the 4300. I've been thinking about either puting a 5300 Vortec in mine, or beefing up the 4300. I think it would be wicked to put down some mad numbers with the 4300, I think it's more unique. But like swartlkk said, v8 has a larger aftermarket and such. But anyways, parts listed maybe? I've been very curious in putting together something like this, especially the blower. My buddy has a '98 Buick Regal GS, blown 3800 V6 and that thing is sick. I would love to have one of those new Trailblazer SS's, 0-60 in less than 6? That's just impressive from such a heavy vehicle. But yeah, very nice truck.

Thanks to all that actually like the v6. I just wonder about the few that bash it. I wonder if they have ever built a engine, or if they have ever even built up a performance engine themselves. I'm talking about building a engine from scratch . Not just changing a head or putting on a muffler or even a air cleaner.
I also wonder just how much first hand knowledge that they actually have about the V6 4.3 motor. Dyno numbers to me are a great starting point. Just numbers to use in your build up. I have disclosed some HP numbers. I do use the dyno as a tool , Just like a wrench is a tool. What really counts is how a motor performs in a vehicle. The Dyno doesn't tell me that I can spin my wheels at 60 mph just by stomping on the gas. Also the feeling of going sideways at highway speeds when you let her rip. Then having everything blur out the side windows and passing cars as if they were standing still, from 60 mph.
I will say that I have more than the 371 hp at the rear wheels. That HP of 371 is measured at the flywheel for the SS Blazer V8 and Seirra. Mine is at the rear wheels after going through the trans, transfer case, diff, and drag of the front wheel diff from the front driveshaft. Not to mention that the Supercharger uses 30 hp just to run. See. Still want dyno sheets to gauge my truck? Or would you like to go for a ride ?

It's not so much bashing the V6...
It's unique to build it up, but for pretty much the same price, you can drop in a V8 with less mods and have more power...
Personally, I'll be dropping in a V8, but part of it is, I don't like the 90 degree V6 sound as much as I do the 60, or a V8

You STILL HAVE NOT ANSWERED THE DAMN QUESTION! This is SIMPLE!! What is so damn secretive that you cannot answer a simple question? You had your truck dyno'd and the video to "prove" it and all I am asking for is the numbers. The numbers would have sufficed a while ago, but this was asked MONTHS ago in the other thread where you went on your self righteous rant about how none of us has ever built an engine. Seems people always try to shift a discussion onto the qualifications of the ones asking the questions instead of just answering the damn questions in the first place.
You also are quite confused on the intent of my questions. I am not "hating" on the V6. As I have said, I have messed with v6 before and I know what they are capable of. But whatever deters the focus of this thread away from you actually proving your claims, right?... I have a responsibility to the members of this forum to maintain the integrity of the information found here.
Well, I'll answer some questions for you seeing as how my knowledge and experience has come into question. I think that everyone here knows and respects my experience and knowledge. Well, that is except you. So I'll give a run down for you of what I have done (deja-vu?), not that I have anything to prove to anyone...
You doubt the fact that I have ever built an engine. You assume that I am just some kind of computer jocky right? I rebuilt my first multi-cylinder engine when I was 9 (single cylinder at 8). It was a Chevy 350 from my dad's '71 3/4 ton farm truck. I did all of the work myself with the supervision of my father. I helped to rebuild a Detroit Diesel when I was 12. I installed pistons, filed rings, installed the fuel supply lines, dropped on the supercharger, etc. I have rebuilt a D8 dozer engine as well as a Cummin's turbo diesel from one of my dad's road tractors (tractor trailer for the lay-man). I raced go-carts from age 9 until age 11 and built the engines that I used (5HP B&S on alcohol).
You question if I have ever built a performance engine. I have, in my possession NOW, a 386HP / 425ftlb 355 Chevrolet v8 (350 w/ 0.030 overbore) that was in my Chevelle and is now on the engine stand in my dad's shop while I am restoring it. The engine was dyno'd on an engine dyno in Canandaigua, NY back in '94 when I, yes, I built it at the age of 15. I lapped the valves in the 2.02 cast iron heads. I polished the crank. I filed the rings. I plasti-gauged the crank journals. I clay'd the pistons to ensure that the 1.6 ratio rockers would not cause piston clearance issues due to the 10.5:1 compression that was expected. I degree'd the cam as well as took rough specs as to lobe separation angles, base circle, and lift. I'm not sure of the cam because it was what was in the engine when I purchased it, but I determined that it was going to be big enough for my purposes. I assembled it MYSELF. Oh and if memory serves me, I built this engine for under $500 and it is solid as a rock!
Call me a liar, I don't really give a damn. I have nothing to prove to anyone, but for the sake of getting past this impediment that you seem to have, I have answered your questions. Now, please, do the same. Scan in that dyno sheet for all to see what $5000 worth of parts into a 4.3L v6 is capable of. No more redirection of questions. Better yet, take that 'ss' of yours to the track and give us some 1/4 mile times instead of being dumb and racing on the street (I mean you did illude to the fact that you could run 8's right? - source). NO MORE FREAKIN' EXCUSES!!!

You're gonna need a lot more than 380 HP to get 8s... Unless maybe, that's the 1/8th mile... Unless you've managed to drop the weight a LOT from the stock 3500lbs or so...

Hell for that you could buy a create v8 from jegs that will put out those numbers.

This is funny. I hear a lot of "I have " , and I will. Not any, My engine. 380 hp big number !! at the crank , What would that be at the wheels? For a 4 wheel drive v6? Then remember that you also have nitrous and that 383hp is before the nitrous is on.
Sometimes people don't believe what they can't see or touch . Why does it matter so much ? I have seen differences of as much as 30 hp from dyno to dyno just because the base numbers and temps were inputed diffrently. I can give you some great numbers by telling the comp that it is 90 deg out. or -14 deg. The dyno is a tool ! Not a fact ! do one test today and the numbers will change for tommorows session . Time slips count not dyno's. there are so many teams that have never dynoed their engines or cars. Do you believe them when they tell you their HP numbers? Weight x time x distance can give you a rough HP # . Without a dyno.
And by the way some shops and dyno guys thought that I had a v8 when I pulled into their shop and looked mighty surprised to see a v6 on the valve covers. Sound can be made to be just how you like it. That is what the major car manufactur do, they have whole sections of people devoted to just making cars and trucks sound good. Jba ceramic shorties, 2 1/2 inch stainles y pipe, High flow stainless cat, Jba 3 inch stainles exhaust system. It does sound good, the important thing is that it sounds good to me.
And i am not questioning any ones ability to build engines what i am questioning is what they know about the 4.3 v6. My engine is in my car and running. Not on a wish list or sitting in a corner. Go back to some of my past threads this has all been dealt with before. You can see outright some of the things that have been done to my Blazer. along with modifying parts to make them work on the v6, and tracking down this and that. Me and my Dremel are on a first name basis. the fun and headaches are worth it. Just want to share what I have done so far and to not start arguments or make foes. This is a fun project.
And where the heck did I say that I ran 8's? I wish, Not with a 4000lb Blazer . Where is this 8's thing ? And street racing is not what I do, I have raced on the street , But it is not a practice. That post is not from me!!
