Friday nite,I was doin my burnout in my 67 barracuda racecar,440,when halfway through it started missing bad ,i pull it up to the line and its missing hard ,like its running on 6 or something.Well ,i back it up ,drive to the pit,pull a couple plugs ,they are fine.Pull a valve cover,and the number one intake pushrod is laying in the hole,looked down to see yhe lifter also out of its bore.came home ,pulled the intake,and number 8 pushrod(intake also) is laying out to.There is no wear at all on anything,the adjusters on the rockers are still tight and where they were set,lifters are not collapseed or worn,pushrods are not bent.no nothing.What could have happened?This has all my friends/experts stumped,any thoughts guys????
thanks craig
