Hi
I did a cylinder compression test on my 68 big block.
This to ensure that the broken exhaust valve rocker did not leave any damage, like U/S valve seat, piston rings.
Looks like if all cylinders pull right over 11 Bar ( 160 PSI ).
I hope the difference between the piston pressure comes due to the old , original untouched L71 heads solid lifters.
What do you think ?
Thanks Gunther
