It could be:
A. worn rod or main bearings. If that's the case you'll have low oil pressure.
B. a faulty "knock sensor" that's supposed to retard the engine timing when it detects early ignition detonation.
50
No it will not. There is something wrong.
By running the vins and serial numbers on the VORTEC engine its self and going to the DMV you might have to pay them $50 but it will give you basically all the information on it! (:
Vortec
The difference in horsepower between stock heads and Vortec heads on a 350 Chevy can vary, but typically, upgrading to Vortec heads can yield an increase of around 30 to 50 horsepower. Vortec heads are designed for better airflow and combustion efficiency, which contributes to this gain. The actual increase can depend on the overall engine setup and tuning.
i believe is from 50 to 60 psi
You just don't mix them.
Regardless of the block, you have to use Vortec heads to use a Vortec intake.
There are 4 different Vortec engines for that year. Stock horsepower at the crank are: The 4.3L (262ci) Vortec V6 has 190hp The 5.0L (305ci) Vortec V8 has 230hp The 5.7L (350ci) Vortec V8 has 255hp The 7.4L (454ci) Vortec V8 has 290hp
when did Chevy vortec come out
will a 4.3l vortec starter fit a 305 vortec?
A vehicle can be shaking and knocking when the speed gets over 50 mph if there is something wrong with the suspension. There might be a tie rod loose, a wheel that is out of balance, or the ball joints could be bad. This is a very dangerous situation that needs to be taken care of before an accident happens.
