Depends on the year, cam, compression ratio. engine warm, 130-165psi, long duration lowers psi, overlap increases psi., solid cam with same duration would be higher than hyd. due to increased valve rate. All reading should be +/- 10%
the 440 engine had 375 horse.
compression ratio is 6:5.1 the compression test should read 120 pounds give or take. hope this helps.
440 engine or the model 440 dodge?
9:1+
125 p s i
All GTX's produced had the 440 engine.
All the cylinders should be within 10% from the lowest reading to the highest reading for a healthy engine.
Should be 110 PSI
It should have a minimum of 70 psi.
Cylinders compression pressure Sentra 1.8 : 192 psi
480 psi minimum
Normal compression on a gasoline engine is about 125 psi.
