Exclamation vacuum diagram 1985 S10 Blazer

Ok guys I know it's been a while but....
I need a vacuum line diagram for my POS and I can't find one.
It a 1985 S-10 V6 2.8 with the rodchester carb and about 40 million vacuum lines.
There is a small picture under the hood that looked good - I'm thinking 20 or so years ago but now it's all scrached up and useless.
Anyone help me out here?

Thanks.

Federal or California emissions?
Automatic or manual?
High Altitude setup?
Optional fuel tank?

Aside from federal or California emissions and auto vs. manual trans, I really do not know how to tell you if you have either of the other two... I just know that there are 10 different vacuum diagrams...

It's never been to CA. so I would assume it's Federal.
Automatic, 2 wheel drive, in Texas so I'm thinking no to high anything (except gas prices) and it has only one tank. It also has a fancy rochester 2SE carb which I hear is only done this year and was not one of chevys best idea.

What I'd really like to do is junk the whole intake and carb and put a new one and a carb with only a few vacuum lines like maybe to the vacuum advance. Next year it doesn't have to pass emissions testing cause it's frickin old!

Anyone make any aftermarket high performance parts for a 6 banger chevy?

Not the 2.8L. I will look for that diagram when I get home from work tonight. It will look like the pile of spaghetti that is the top of your motor!... I should know, I had an 85 S10 pickup with the 2.8L.

Default do you have the 2SE or the E2SE

I have the California 5 spd version with the E2SE carb, (it has the Throttle Position Sensor, TPS in it) and I guess it's part electronic, and man my truck has no power, I wonder if yours being only 2WD is more powerful than mine. Let me know what you replace your intake and carb with I may do the same.

If you want any close up pictures of what I got in terms of the vacuum lines lemme know.

Don't really think a picture of your spagetta will help me sort out my spagetta :-)

I now have it almost right, I had a bad lag when I hit the gas and it wouldn't pass the state inspection. I replaced some lines on the back of the carb and the EGR which was total trash. The NOx which has to be 2750ppm was over 3300ppm and now it's 1375ppm so it was the EGR causing it to fail. It runs better now and I don't have the lag but the idle is rough. My 12 year old say he get a massage ever time we stop at a red light.

Good news is it's now 25 years old and never has to pass Texas emissions test again.
Bad news is the lines still arent right and I hate to keep messing with them.

The saga goes on!
