Took the 3A out last Sat. Everything running beautifully. Decided to push her a little harder than normal.(still kept it below 4500 revs) All of a sudden, a noise I was not familiar with and didn't like. Make a long story short, broken pushrod, intake #3 cylinder. The good news, was already thinking about pulling the motor and doing a major rebuild. Going to 87MM, different cam, port and polish the head,new rear mail seal and more. Any ideas would be gratefully appreciated. Motor is out of car, now is the time to do it properly.
