factory recomeded compression ratio in foot pounds for a 1993 Chevrolet s10 truck with a 2.8 engine?
Compression ratio in a vehicle usually refers to the difference of cylinder displacement at top dead center versus bottom dead center. For example: if the volume is 1 cubic inch at the top of the piston stroke and 10 cubic inches at the bottom of the piston stroke, 1/10=10:1 compression ratio (or is it 9:1? Close enough for government work.)
Foot pounds is a measurement of torque. The two most common measurements of torque on a vehicle is either the twisting force exerted by a vehicle's engine (torque/hp engine specs) or how tight a bolt is supposed to be turned (lb/ft of torque specs for a bolt).
Other than the fact that compression ratio and foot pounds may be used to describe a vehicle's engine attributes, they have nothing else in common.
Need to know what size engine it has to answer correctly.
8.5 to 1 compression is factory stock.
10.5-1
Compression ratio on a 1974 Chevy 350 in a Nova was 8.5:1.
8.3:1 is stock
The compression ratio of a 350 Chevy engine usually ranges from 8.0 and 9.0 to 1. This provides a good balance of fuel economy and power.
You can refer to your user manual to ID the rear end gear ration in 80 Chevy pickup.
9:1.
Supply the vehicle identification number to the nearest dealer and he/she can tell you what ratio you have.
with higher compression pistons
YES. That is a direct bolt on with no problems. The heads will bolt on, but the compression ratio will be different. Depending on which heads and which pistons, the compression ratio could be a lot different.
It depends on the gear ratio of the rear ends. You can find this out in the glove compartment of your truck. It should tell you there. Hope this helps you out.
