Combustion Chamber Volume
The few things I can find are telling me 56.7cc's. Is that correct for a '98 4.0L?

Re: Combustion Chamber Volume
My '00 FSM says 49.9 - 52.9??? I belive the heads changed from '98 to '00 so that may not be accurate for my volume

Re: Combustion Chamber Volume
No. According to the FSM, 4.0 heads of all years have a combustion chamber volume of 55.2-58.2cc. I've cc'd two 4.0 heads (7120 casting); one was 56.5cc and the other was 57.0cc.
