Is the 4.3 v6 Chevy vortec engine a interface engine or a non interface engine in regards to the timing belt and the valves?

It does not have a timing belt, It has a chain and gears. And no it won't bend the valves if the chain fails. It has valve reliefs in the top of the pistons. New answer: I would run a fuel pressure test on the fuel pump. It should have
60 to 66 PSI NO lower and no higher.
I would first check the fuel filter, sounds like fuel filter stoped up. You did not say what year it was, But if its not newer then a 2005 the fuel filter will be in the drivers side frame rail close to were the transmission crossmember bolts to the frame. You will have to lay under the truck to see the fuel filter. You might want to check the air filter too. NEUTZ.

1999 zx2 timing belt breaks will the valves be bad?
the ZETEC engine used in the 1999 ZX2 is a non-interference engine. This means that the pistons will not contact the valves when the timing belt breaks. Because of this, the valves will not be bad if the timing belt breaks
What is injection timing?
operation of engine fuel valves as required by engine loads.
Does a 2007 Chrysler PT Cruiser have an interference engine?
Yes valves can bend if the timing belt breaks.Yes valves can bend if the timing belt breaks.
What does a ticking sound which increases in frequency with increase in speed coming from the engine mean?
It sounds like the engine timing. The sound is coming from your engine valves. They're not in synch with the rest of your engine. It could also be that the valves are worn out. I'd check the timing first, then the seating on the valves.
What is a interference engine?
an engine where, in the event that the timing is off or if the timing belt breaks, the pistons can collide with the valves and actually do damage.
What is variable injection timing?
operation of engine fuel valves as required by engine loads.
What is a zero tolerance engine?
Also known as a interference engine, A zero tolerance engine is an engine that would damage the valves and likely the pistons without correct timing. This would occur because the valves and piston have the ability to come into contact with each other. With correct timing, this is not an issue because the piston travels away from the valves as they travel into the cylinder. When timing is lost, the piston could travel toward the valves as the valves enter the cylinder, resulting in severe damage to both. This is not an issue in a non interference engine because the piston and valves will not contact each other if timing was lost.
Honda Civic valves interference?
do you mean is a Honda engine an interference engine? in which the valves will get bent by the pistons if the timing belt fails? then yes.
Will a Chevy 350 idling bend valves when timing jumps?
NO not that engine.
Does a broken timing belt ruin the engine?
When a timing belt breaks, the timing of the valves' movement is no longer synchronized with the crankshaft (and the movement of the pistons). On most engines, if the valves open when the piston moves upward, the valve and piston hit each other, which can break off the valve, allowing it to cause more damage to the engine. These types of engines are called 'interface' types. However, on some engines, the valves don't open far enough, and the pistons don't come up high enough for the two to come into contact. So when a timing belt breaks on these engines, the engine stops running, but no internal damage is done. These are called 'non-interface' engines.
Do you need to check my valves after your timing belt broke?
Maybe, it depends on if your engine is an interference engine.
Will an engine seize from jumped timing?
It could if the valves made contact with the pistons in an interference engine.
