NO. It should start at about 150 LBS. PER cylinder. And you can't have anymore then a 15 Lb. difference in any cylinder, are the engine will idle rough.
around 80 ft.llbs. or higher is usually good.
A good 454 will have at least 150 PSI per cylinder.
That engine FRESH / NEW should have 150 LBS. compression per cylinder. If you have more then 20 LBS. difference in any cylinder then it is not in good shape and a good VALVE JOB is probley in the furture.
You will have to do a compression test yourself to know that. A engine that is in good shape should have at least 150 LBS. per cylinder. There can not be more then 20 LBS. difference in any cylinders. It has to have at least 100 LBS. for the cylinder to fire at an Idle.
Run a compression test before you spend too much time checking out other potential problems. If the compression tests good, try swapping the fuel injector with a good cylinder and see if the dead cylinder moves.
Do a compression test on all the cylinders. You may find a mechanical problem with that dead cylinder.
i'd like to see 130-140 psi. gotta have 90 to fire.
Good compression, good heads, good cam.
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.
good pump, 66 psi , key on engine off, less than 60psi, hard starting, I know , its crazy...
Yes very well
