Default LT-1 timing gear

Guys...does an LT-1 also have nylon on the original gear ? Nylon was for noise reduction purposes.....seems kind of silly on an LT-1 as noisy as they are.

If the valves are correctly adjusted they are not noisey.
Read the Hinckley paper on 30-30 and LT1 adjustment.

MelWff……...mine are adjusted to the specs called for in the 1971 Chevrolet Service Manual which is intake 24 and exhaust 30 hot engine and they sound perfect to me. I would love to read the Hinckley paper to see what it says but I have no idea where you are sending me to 30-30 ??

That's why you find them noisey.
Read the link below specifically the revised LT1 settings, runs great and not noisey.
