98 S10 Vortec V6 4.3 Intake Gasket Replacement Part 1 of 5
Well I think I have a bad intake gasket on the drivers side. I had a small
coolant leak coming from the water pump but now I have a pretty bad leak
that is getting on the Exhaust
manifold on the drivers side. Going to take it off and have a look. From
what I have seen online intake gaskets are a pretty common thing on the 4.3
and 5.7 vortec engines. I will try to be as detailed as I can to help
others doing this same job.

4.3L/5.7L Vortec V6/V8 | Throttle Body Blade Mod | 262/350ci
Easy free way to gain some bottom end response. Does not gain horsepower like companies
claim. Please watch vid to end and read description. Thanks.
The mod is to remove the diffuser / restrictor off the bottom of the blade
to increase airflow into the engine. free alternative to a $40 cfm tech
Make sure you reset the computer (reset by disconnecting battery)
Took me about an hour from start to finish
please don't tell me that my front 2 cylinders will lean out, because that
is crap. there is no need to restrict the EGR due to this mod....

How To Clean Your Vortec 4.3L V6 Throttle Body
I show how to cheaply and quickly clean any throttle body, but specific to
my 1999 GMC Sierra 1500 Stepside with the 4.3L v6.
I created this video because I was having an issue with my truck starting
up rough. It turned out that the idle air hole on the blade was completely
clogged with carbon caused by back-spray when the engine is turned off.
All you need is a Flat Blade screwdriver for hose clamps, Carb Cleaner, and
a Toothbrush or rag.
Engine rebuild part 1
This series is available on DVD Here is the link
We are rebuilding a GM 350 5.7 engine. Now in this particular case we
are also going to upgrade the engine to a 383 6.0 This is called
building a "stroker" motor. In other words we are increasing the "stroke"
of the engine which increased the torq & horsepower.
If you are able & wanting to rebuild an engine, this video should give you
a good overview of what to do. If you are having someone else build an
engine for you, you will be able to see what's involved in the process
