The front cylinder
The Chevy 250 Cubic Inch inline 6 cylinder are numbered from the front to the rear, 1-2-3-4-5-6. So # 1 is on the very front of the engine.
The base engine was a 250 inline 6 cylinder. Also could be ordered with: 292 Inline 6 307 V8 350 V8 396 V8
As far as I know, the 1987 Chevrolet G10 Van did not come with a 250 Inline 6 cylinder, and I have never seen one in this year model van. The only 6 installed was the 4.3 liter V6. The firing order of the 4.3 is 1-6-5-4-3-2. There was a 292 Inline 6 cylinder installed in the fullsize pickup that year and the firing order for it and the 250 inline 6 cylinder are the same at 1-5-3-6-2-4.
how do i set the timing on a 81 gmc 250 inline 6 cyclinder ?
It was originally rated at 155 but later model engines produced around 110 if it's an original 250 inline 6 it's probally around 150-155...
No, the cylinder head from a 292 Chevy six-cylinder engine will not fit on a Chevy 250 engine. Although both are part of the Chevrolet inline-six family, they have different head designs and mounting configurations. The 292 has a larger bore and different port sizes, making them incompatible for direct swapping. If you’re considering modifications, it’s essential to consult specific engine compatibility resources or experts.
I can only guess it is an inline six cylinder. The firing order would be 1-5-3-6-2-4.
Yes it will with no problems.
The 1963 Chevy Nova SS typically came with a 230 cubic inch (3.8 L) inline-six engine as the standard option. Some models could be equipped with a more powerful 250 cubic inch (4.1 L) inline-six engine as an upgrade. These engines were part of the Chevy inline-six family, known for their reliability and decent performance for the era.
No. You will have to get v-8 mounts.
The inline 6 cylinder 250 Ford firing order is 1-5-3-6-2-4 Rotor turns clockwise.
The coolant flow in a Chevy 250 inline 6-cylinder engine typically starts at the water pump, which draws coolant from the radiator through the lower radiator hose. The coolant is then pumped through the engine block and cylinder head, absorbing heat before it exits through the thermostat. Once it passes through the thermostat, it flows back to the upper radiator hose and into the radiator, where it cools down before returning to the water pump. This continuous cycle helps maintain optimal operating temperature for the engine.
