I just raced my buddy in his really quick mustang like 7 times in a row, all high speed races (145+)On the last race I thought I was in drive and when it was time to shift to OD, i shifted, but hit nuetral because i had mistakenly already been in OD, and smacked the rev-limiter a few times. After I slowed back down I realized i had a REAL loud tapping noise coming from the motor. Almost sounded like a really loud lifter tick. Also, was thinking it might be a bent pushrod or two. I'll pull the pushrods out tomorrow and check them out. The car drives and idles fine, no smoke, no leakin oil or coolant. Just the noise....what do you guys think I could have done???? I hope its nothing major. Also, do you think hooking it up to Auto-tap could help diagnose it? My buddy has it and I thought we would hook it up and see whats going on. Any help would be GREATLY appreciated.
