Dropped a valve
Dropped a valve on my fresh built 540.The exh. valve on #2 cyl. broke about 3/4 of a inch down the stem.?Wtf.Ferrea 6000 series valves,4.5 bore with 4.250 stroke,rhs heads,lun cam 740 exh 758 int lift.Put a new radiator in the car and was in the shop checking the car fired it up and ran it for 8-10 minutes only got to 150,so got out of the car and started checking for leaks,bliped the gas by hand a couple of times to help put a little more heat in it,sounded funny so jumped back in the car to check oil psi it was 55,hit the gas one more time(dumb ass)to clear it up when it came back to idle,it locked up.!!
Never seen one break at the stem like that,zero passes on the motor,only shop time may be an hour and half of run time.one pass down the local road in front of the house,it saw 6000 rpm on that pass,but lots of run time after that.Roller cam and howards roller rockers crower roller lifters all brand new.pulled the heads and the others 7 cylinders are happy,No contacts marks on any other valves or the pistons.WTF??
