timing chain.

A bad timing chain would cause all the cylinders to be about equally low. there is some other problem also, You can check the timing chain by pulling the dist cap, watching the rotor and turning the crank pully with a wrench, then seeing how much rotation in the opposite direction before the rotor moves. and you get a few more ponies by using a double roller chain and setting the gears dead on , the smog 460's ran retard on the cam as a cheap way of emission reduction.
