Re: Bronze or Aluminum timing gear
FWIW:
One (1) experience & one (1) opinion:
After speaking to Mr. McEachern, & his solving my noisy fiber/steel timing gear problem with a higher lift "new" cam, I would trust whatever he recommends for your particular needs.
I bought his recommended aluminum timing gear which matched my McEachern made crankshaft gear installed by Mr. Ron Kelley & it is "not" noisy ......... even when listening with an Amazon.com mechanic's stethoscope.
I had one fiber timing gear fail years ago on a modern car where the car had to be towed to a shop; however, it appears it would take a head on collision to make the aluminum timing gear fail.
Hope this helps.
