Hey all.

The other day I noticed the butterflies were not opening all the way on my dad's FE 427 carburetor. This is the same motor that was bending push rods earlier, oil restrictors were installed and the problem seems to have gone away.

Which leads me to my question, what reasoning caused the speed shop to adjust the carburetor linkage to where at full throttle the primaries are 7/8 open and the secondaries under 3/4 open? (Barry Grant Claw Silver Series 750 mechanical secondaries, double pumper) did the mechanics do this to limit power to not bend the push rods? Sounds to me, if that's the case, they pulled a fast one on us.

Great now I am even more confused! I remember oil relief valves in the back of the block being mentioned. Could the idiots not utilized those valves to reduce the hydro lock on the push rods? Were the push rods bending because of the oil pressure? (100-110psi cold)
