Because when a customer hands you a check for 12K to build his engine you don't check spring pressure???? Thanks for the response but...... everything and then some was checked on this engine. Keep in mind this 440 had been running fine since 2014. A single tie bar out of 8 failed 3 months ago. We sent the bad roller pair to Comp, they said sorry and fixed the galled two lobes on the cam for free and assured us that they have corrected what may have been a quality issues with that production run on their roller lifters. All is good however, I now use Johnson lifters on all of my builds. They truly are the best hydraulic roller lifter money can buy. Check them out!!!
