You guys know of any good ones? I'm looking for performance oriented 4.3 sites, more than baggin/wheels/interior sort of sites.

 

Try this one: http://www.automotiveforums.com/vbulletin/index.php Click on the Chevy Blazer section. This is where most of the 4.3L stuff is posted. It is geared more toward maintenance, than performance. You should also check out the Syclone/Typhoon website for 4.3 tech.

 

I tried to get one going on here, but was told they dont have anything to do with our trucks, even though the 4.3 is standard equiptment. Instead we have forums for LT1's because they are "simular to the newer F-bodys", D-max's, 8.1's, even 67' to present F-bodys. And dont forget those awsomely powerful Northstar Caddys that have the fact there made by GM in common with LS1's.

Anyway, not to rag on the mods for whats still a great site. The only forum with any half assed performance info on 4.3's is S10Forum.com. Check out the "262 V6" portion. Its not great but its all we got.

 

Thanks Snake.

Would you mind if I throw you some pm's about the 4.3 from time to time? Doin a few things for a buddy w/ a blazer.

btw. is the 4.3 V6 not similar at all to the ls1. what is so different besides the lack of 2 cylinders? Not being a smart ***. I would just like to know.

 

Sure, ask away.

The 4.3 is just like the vortec 350 and 305 from 96' and up, just with 2 cylinders missing. It really isnt anything like the LS1, then again nothing is.

 

I have to say something to that note, there are a couple of different models of the 4.3. There is the odd fire, and the even fire - one has the balance shaft above the Cam, the other doesn't. Then there is the "baby" lt1 that is a 4.3 liter v8 that is found in Buick Roadmasters and Caprice cars. I've built a 4.3 for my brother's 94 Sonoma, I had to go through the pain of finding out alot of this stuff on my own. Yes in theory the V6 4.3 is a 350 minus 2 cylinders, but try to put an exhaust gasket from a 350 up to a 4.3. You'd think all you would have to do is chop off the end port, but it doesn't work, there is more seperation between the paired ports than on a V8. I kept telling my brother to put off on getting 4.3 headers because I would just modify a set of shorty V8 headers I had. It didn't take too long before I figured out it wasn't going to work. One good thing for the 4.3 is that it shares all of the accessories, you can use the V8 water pump, power steering brackets, alternator brackets, everything, and if you're wanting to delete the smog pump and AC - just find 350 brackets from something that didn't have it, it'll work.

Basically everything we did to this 4.3 came from Edelbrock, or at least is an Edelbrock product bought on Ebay. I picked up a mild Edelbrock roller cam, intake, carb, headers, and valve covers all off Ebay. The rebuild kit came from Ebay as well with the upgraded HyperEutectic pistons.

 

seriously i think its kind of a shitty deal that we cant have a 4.3 forum honestly why not

 

I think its really because the ones who decide that dont care. Its there LS1 site and there only going to add non LS1 stuff THERE interested in.

You can be mad at them for it, but either way the site belongs to them, not the members.

 

REVOLT!

I got ahold of a guy who has done a butt-load to his 01 s-10 4.3
-heads
-cam
-tuning
exc.

Anyways he pointed me out to a decent site. S-Series Forum

---btw, you have to register first. Well worth it if you are at all interested. A bunch of good info and exc.

 

i could understand if the 4.3 didnt come standard in a full size but they do
