There is a way to disable two cylinders to make the 8 operate reasonably efficiently as a 6. You remove the push rods (or rocker arm), (or the cam follower on an overhead cam engine) to the two cylinders (NOT on the same crank journal) which are opposite in the firing order, (the journals will be 90 degrees apart in the 90 degree block)
If you just disconnect the spark plug, the unburned fuel would be pumped into the exhaust and cause back fires there. If you remove only the injector, the engine would not be just pumping air from the intake but ALSO some of the fuel spray from the other injectors.
In an injected engine, it makes sense to disconnect the injectors to the two cylinders.
By disabling the valves, the cylinders work as an "air springs" returning PART of the energy spent in compressing the air inside.
Sparking in the cylinder would have no effect and removing the wires would increase the chance cross-firing in the distributor, so leave the spark plug and wire in place.

Dragging along two cyls with out spark or fuel. Manufactures shut off cyls in rotation so the engine does not have cold cyls to get started back up. New electronic V-8 engine technology allows my 6.0 liter running on all eight cranking out 400 Hp to get 24 miles a gallon on the highway. The Pontiac GTO weighs 4,000 pounds and has two over drive gears 5th and 6th. So for better power and economy buy a new car.

NO! You cannot change a V-8 into a V-6 without changing the hardware. The two engines are physically different and cannot be converted with reasonable efforts.

"When you figure it out, tell chevrolet as they had a 4.3 v6 for years then decided to make a 4.3 v8 also.."
so why would they need to know? they obviously already do. and besides, if you take away two cylinders from a v8, is it still the same displacement? no....... the chevy 4.3 liter v6 is a 350 with the two front cylinders missing, but it's made to run w/ out them. sorry, i just like to point out answers that don't make any sense whatsoever.

Yes, Disconnect the rocker arms, remove the push rods & sparkplugs for the two cyclenders that share the same connecting rod journal. The engine will run ruff because the power cycle will be out of phase. However it will run.

Yes. Disconnect two spark plug wires.
Okay, seriously, why would you want to do this? The engine will run like crap and you will not save fuel. In fact, you will actually LOSE fuel mileage.

Just pull 2 plug wires off is the only way.
If you wanted to make a 2 dr. out of a 4 dr. car, you could weld the back doors shut, also.

Yes, but it would run like crap. Take two pistons that are opposite of each other out and unhook the injectors. It would miss like 2 cyl down. So why would you do this.

no, but i know what youre thinking. take two plugs and kill them you cannot do that either. the fuel going to those two dead cylinders if it isnt burnt it will seep into your oil pan and wash out your bearings causing you to blow the engine.
