Longer push rods ?

[danny waters sr]

I started this topic and have made the changes and at first i saw a gain..

Since then ,i had alifter come apart and found every part of it in lifter tray (lifter come un-locked)...

I have since ordered a new set of lifters (not shubeck type).

I kept the long push rod when i changed the lifters.

Now i am knocking off the rocker arm in high gear in the 1/4 only.(not rollers )

Is it possible the old lifters were worn out and that is in fact why the longer push rod picked up the performance ?

Is it possible now with new lifters that i have this problem because of the longer push rods?

I have never had this problem til i installed the new lifters....Any suggestions or answers please ?

Thanks in advance......
