If you’re getting some vibrations to go along with the noise like I am getting with my new reman 4500 then that is a different story.
What type of vibrations are you getting. I do have a light occasional vibe I notice in 3rd & 4th gear at a certain RPM. Mostly a high RPM like 25-2800. Which is past my normal shift RPMs for a 454. If I push the RPMs closer to 3000 them my vibration goes aways. My flywheel is new along with my clutch and pilot bushing.
