Is there a 1.6 ratio for a 2.8 V6?

Is there a 1.6 ratio for a 2.8 V6?

They come in 2 varieties. 1.6 and 1.5 ratio (stock). The 1.6 will give more lift and a little more power. If you do all of these stages, expect to spend close to $2K. I shopped on Ebay, Summit and Jeg’s, and IIRC this is approximately what I spent on my 3.4. The result will be a 2.8 that puts out approximately 155 to 165 horsepower.

Are there any performance mods for 2.8 V6?

All of this also applies to the 3.1 and 3.4 resulting in a little more power due to larger displacements. You can go completely wild and do internal mods, (pistons, balance, porting, bigger cam etc) but that is not the intent of this thread. This will give a healthy 2.8 that will pull up hills easily.

Is there a 60 * engine for a 2.8?

Since I have seen so many threads about wanting to improve power in the 60*, maybe I can offer some tips on helping these engines perform better. The first issue is the factory camshaft in all of the S10 2.8s is JUNK (as far as performance is concerned).

How much horsepower does a 2.8 liter V6 have?

The result will be a 2.8 that puts out approximately 155 to 165 horsepower. All of this also applies to the 3.1 and 3.4 resulting in a little more power due to larger displacements.

How do you adjust the intake valve on a Chevy?

The process is the same for stamped steel rockers (like the ones pictured) or roller tip rocker arms. When the exhaust valve just begins to open on the first cylinder in the firing order, adjust the intake valve by loosening the adjusting nut slightly while spinning the pushrod until you feel lash in the rocker arm.

How do you adjust the intake valve lash?

When all of the intake valves have been set to the proper valve lash, you can adjust the exhaust valves. Utilizing the same procedure as with the intake valves, you need to turn the engine over until the intake pushrod moves all the way up and rotates just past maximum lift.

What happens when a valve is adjusted too tight?

If adjusted too tight (the plunger fully compressed) the valves stay open slightly, and do not close all the way. This removes the important cooling time (lash) that removes heat from the valve stem.

When do you switch to an adjustable valvetrain?

If we switch to solid lifters it is mandatory that we convert to an adjustable valvetrain (I would also say that converting to adjustable valvetrain is mandatory in ALL racing applications as well as any application where we want to have accurate control of our valve lash setting). Not doing so is asking for serious problems!
