  • Quick Question Please

    I baught a engine with for my Grand Am its an 04 3400

    My question is.....Is 210 compression for this engine a good compression. An what is normal compression for this engine.
    Thanks

    210 on all cylinders? Basically anything over 170 is pretty good. But you want to have compression between all cylinders to be within 10-15%.
