I am looking to improve low end torque and overall power to my '79 blazer, it has the 5.7L 350 as far as I can tell. I am thinking new intake manifold and 4 barrell carb?

Improving Low End Torque and Overall Power to my '79 Blazer?

yea, a new cam would help a lot as well, but they are kind of a pain to swap in truck, imho...
You have to give us a budget. How much are you looking to do?

Playing with ignition timing might help a lot too

Could swap out gears too for some slightly lower. But you would reduce topend speed and gas milage at high speed.
Have you checked out edelbrocks power packages?

get you a edelbrock performer package (cam, air intagake and 500/650 carb), put on some long tube headers and a true dual exhaust system with at least 2 1/4". You can also add new power sparks, ignition cables and maybe a new H.E.I ignition. This should push it up to a little over 200 hp and good for 400 nm. I did these modifications to my '79 Blazer and it runs great. The next weeks I'm going to swap my diff gears from 3.73's to 4.56's. I hope that will be okay with my 35's Baja Belted.
I think the biggest change you can make it to regear. Even with a built motor if it is out of the power band it will be a dog. In my 84 I went from a 305 with 3.08s and 235 75s to 4.11s and 33s and it made a huge difference. Sure it won't do 150 mph ( hey with the 700 it had a final drive of 2.15), but who needs to ever go faster than a 100 in a truck. Plus the mpg actually went up because it doesn't lug the engine. Now it has a mild 350 and really has good power.

before i add or swap parts, i examine what i already have to work with. is the carb setup, timing, fuel pressure, plug gap, etc. most of that stuff won't give you real power gains, but can help drivability issues, like improving throttle response.
be careful if you regear. you still need to be able to hit 88mph for the flux capacitor to work.

Lol. I am going to do the work in parts, I was looking at the Edlebrock power kit thingy, its like 1700, I planned on doing it in pieces, so I am going to hold off on that, plus my heads are pretty new already, the engine was rebuild 2 years ago, and new heads were put on at that time.
headers will be your best bet... performance begins with the exhaust... Be aware, you'll get what you pay for...

So headers first? Then RV Cam? Then...? I want decent MPG cause I have to drive about an hour to get to where we take our quads too. I need to get my gas gauge fixed, it says "e" all the time 
yup, exhaust first.. I'd go over the topend all at once, do the cam, intake and carb at the same time..
Don't forget, a proper tune is the most critical factor..
What are your plans for tire size? it matters...

Allright lighten up Francis.....
you need to have a sense of humor.
Anyhow unless you plan on running 6 grand go with some 1.5 diameter primaries into about a 2.5 to 3" collector, the longer the tube the better for torque. Then run 2.5 duals through some turbo mufflers of some kind.
Then work on the cam.....CALL a cam manufacturer and tell them exactly what you would like to do with the vehicle, have your tire size, gear ratio, trans type, heads, C.R., carb size, etc. They can tell you what will work best.
Good luck, and WELCOME

Haha I was just ****in' around. I like to pretend to be all serious.
Can you just reccomend some Headers? I am not sure what to look for..
And what are soem CAM manufacters I should call?
