I just had a 350 rebuilt and will be running it Saturday. It sounds like a top end ting-ting-ting almost like out of adjustment lifters. I adjusted the hyd lifters 2 times and the noise is still there. Do anti-pump up lifters sound like mechanical lifters? Otherwise, the motor seems fine.
any ideas......

have you tried checking the valve springs. with covers of and engine running put your hand on each rocker arm and push. you should determine which it is.

We have checked each valvespring/pushrod with a stethoscope with no clear indication of which one is causing it...
Putting it on the trailer in 4 hours. Any other ideas?

pull plugs make sure pistons arent hitting them. without actually hearing the noise it will be hard for anyone to determine what it is..

We just did a compression check. All cylinders right around 140psi. I have the engine builder coming over soon to take a listen.
I figure I will either win or blow up trying....

I blew up trying.....Car temp went over 240 after 60 or 70 laps. Very low on power. Now I need to tear it down to find out what happened.

Check to make sure the timing gears are correct. If they are off you will have this problem. Just a thought, since you gotta take it apart anyways.
