GM performance links with a lot of Surburban information:

Here is a start to some links for you guys with Surburbans. I hope these will get you started and save you some gas $$.

Anyway, like I said, it is a start. There seems to be a general consensus that everything I previously mentioned: better intake, better exhaust, a chip, etc., works to some degree. People have also had varying luck with throttle body spacers, too. There is also a product out called a 'Tornado' which breaks down the fuel more before it reaches the combustion chamber. I have heard good things about this product. It is a simple fit into the intake hose and is relatively cheap. Keep in mind that the manufacturer's claims for gas mileage increases, no matter the product, are usually lower than 'real world' results.

You also might find some really good stuff in the tech (or bulletin board) section on pirate4x4.com. There are a huge number of folks on that site that are all about GMs. Here is that link:

Chevy - Pirate4x4.Com (http://pirate4x4.com/forum/forumdisplay.php?f=17)

And here is the link to pirate's GM FAQ:

If I find other stuff or links, I will post them up. Hope this helps....

This is from Larry (Warlord) and is relating to adjusting valves:

Re: Need help adjusting valves


This is out of the GM service manual

Valve Clearance Adjustment




Turn the valve rocker arm nuts clockwise until all of the valve lash is removed.
Turn the crankshaft clockwise until the alignment mark on the crankshaft balancer is aligned with the notch in the engine front cover tab.
Look at the number 1 cylinder valves as the crankshaft balancer alignment mark approaches the notch in the engine front cover tab. If a valve moves as the alignment mark moves into position, the engine is in the number 6 firing position. If this happens, turn the crankshaft clockwise 1 revolution in order to reach the number 1 cylinder firing position.



With the engine in the number 1 firing position, adjust the exhaust valves for cylinders number 1, 3, 4, and 8 and the intake valves for cylinders number 1, 2, 5, and 7.
4.1. Turn the valve rocker arm nut counter clockwise until the valve lash is felt in the valve pushrod.

4.2. Turn the valve rocker arm nut clockwise until all the valve lash is removed.

Zero valve lash can be felt by moving the valve pushrod up and down between your thumb and forefinger until there is no more up and down movement of the valve push rod.

4.3. When all the valve lash is removed, then turn the valve rocker arm nut clockwise 1 additional turn (360 degrees).

i dont have a link but information ..... on chevy blazers from the 80s style the rear driveshafts vary from auto transmissions to manual transmissions ..... the U joints are 1/16 inch bigger in the manuals and have outside clips......auto are smaller and have inside clips...... so this also means the rear yolk differs from auto to manual ....the driveshaft my dad got is from an auto so it will not fit in my truck and we learned the hard way so heads up to those of you with blazers :) (suburbans might be the same way) also i would check the front shaft for this same thing since i did not work on my front :thumb:

Just to name a few. And remember that you can mix and match some stuff. And some of these links are good for other rigs as well. I need to get the wife '94 S-10 Blazer going so I ca do a real build thread.
