Alright, i have a '96 burban, and wanting to tweak her out a bit.  It is the ck1500 series.  I have the base 350 with the 4l60e tranny.  That's pretty much it on what she has.  This is what i am wanting to do, and need to know what might be the best route, cause i also need this to be emissions friendly since it is my daily driver.  I want her to scream down the road.  I was thinking of going one of two ways, buying alot of little parts over a period of time, or just buy one or two major items at once.  The small items are,

Airaid throttle body spacer
Airaid intake set up
Small pully kit
Hypertech low temp thermostat
Hypertech Performance Programmer
Electric fan setup
Limited slip posi rear end
and i might go ahead and add one large item cause i know i will never get all the power i want out of those items.  Now the large items, and these are the ones i need help with, i can put them on, just dont know how to tell what i need.  Supercharger kit, turbo kit, or Fuel rail injection intake and all the fun stuff that goes with it.  Or could i do this, buy a built already 383 stroker block, and put on my intake, or maybe the fuel rail intake. Cause i know that i can get all the horsepower i need the engine by itself, but i dont know what i need to know about setting it up with what so it doesn't send my computer into a meltdown.  Also i was thinking of mounting an aftermarket elctric fuel pump and replumbing the one that is in the tank.  Can i do what ever i want to the truck and then just buy a programmer and recalibrate everything to my new setup and let the computer take over.  Or am i totalling screwed cause of the computer.  Any help would be greatly appreciated and in general, i would just love to know.  Knowledge is the most wonderful thing in the world.  

The good news is you have a '96, which is OBD II equipped so you've got more computer tuning possibilities, and you also have the Vortec heads and injection system.

My advice, forget the electric fan system, stick with the clutch fan. I'd say to get the most out of your ngine, upgrade the cam and valvetrain. The factory cam in those motors is pretty weak, a better cam profile that'll make the most of the Vortec heads will give you the most gains.  

So you suggest changing out my cam?  How much more will that give me?  I have heard that my year model engine is an awesome motor, and alot of people do swaps with them in older cars and they use the heads on them.  I guess after that i could probabley put on the supercharger, then buy the computer programmer and set to all the new parts i have on it.  

why do you want to supercharge so bad?, on the street they do impress but are troublesome and hard to live with... i would keep the stock fans and fule pump along with the stock fule injection, it is good enough from the factory to make all of the power your 4L60E can handle... as stated above you would get the best bang for the money by upgrading the cam and heads, machining the heads are very important because the springs can't handle much lift and the heads need to be worked to accept new ones; you sould also consider screw in studs because the stock press-in ones will tend to pull out with a performance cam, especially once they have been tanked... call around to the cam companies and they will steer you to one that will perform like you want, no larger than .500 lift(something in the mid .400's would be better), any larger and you will reach the limits of your intake and injectors and it wont idle right and you will have surge problems at stoplights with the stock torque converter... a comp cam part 08-412-8, grind number XR264HR, would be my choice but it pushes the limits of the rest of your set up; you will defintally need to have your computer recalibrated  

Alright, yeah i guess i keep forgetting about all the other stuff.  That does make sence, since i am not messing with the tranny, i have to base what i do on what it can handle.  I will think about replacing the fuel injectors just because they have over a 100,000 miles on them.  The tranny has 30,000 after a rebuild.  And the rear end is all original. So i know i need to address that first off.  How much would i be looking at increasing my hp if i do the cam and the heads?  And once i get the programmer it should help to make everything work together?  I hate computers.  HA  

Do you know if there is an entire kit i can buy with everything i might need in it?  

for cam, heads, and upgraded computer i think you can expect 30-40 at wheels along with a good bit more torque especially if you do a little porting on the heads, also consider roller rockers(make sure you get self-guiding ones, they will have little rails on the side that index off the valve) which will be good for about 10 ponies... i cant tell you right off hand but i am sure comp or any other valve train company will be more than glad to tell you of a reputable company that can help you with the computer aspect of your build  

How about this one, someone told me to replace the block with a GM zz383.  I was readin up on it, and it says it is not for fuel injection.  Would i be able to do something like that.  Get a long block and go from there?
