Hey guys,
I've done a search but can't seem to find the answer to my question. I've got a built RB30 short block that I bought off of somebody recently, it's never been used since being assembled and the engine has been balanced. However I noticed something, the crank still has the narrow oil drive gear and I want to have a crank collar installed.
My question is: will the engine need to be balanced again after installing the collar?
Cheers.
