Re: balance

The 4-5 grams of oil is what is figured that is inside the oil passages in the crank. The 427 FE steel crank is figured with 15 grams because the rod journal is hollow, I guess you have to do balance work to know that. If you are so much of a expert, how many balance jobs have you done personnaly? Don't criticize some one if you don't know yourself. It is according to the rpm range of the motor on what you do on over-under balance of the crank.
