Hey guys, the fun continues......I had my BBC 454 crank balanced
along w/ the rods & pistons. I added a internal balance damper/
flywheel combo & the thing vibrates like hell?? At idle it's not
noticeable, but at the rpm's go up it's felt throughout the boat,
thru the steering wheel and the floor. I first thought it was the
pump. I disconnected it from the motor & it's still there. What
the hell?? Can I put the external balance damper/flywheel back
on, or will that not work since the cranks had mallory added to it?
If, since the crank has been (supposedly) internal balanced, will
the external balanced combo cancel each other out? What else
could cause this or has anyone had this scenario before??
