#48 head combustion chamber volume
Do all #48 heads have the same combustion chamber volume? If so, what is it?
I notice that these came on 350, 400 and 428 engines in '69, The advertised compression ratio was 10.5 on the 350 and 10.75 on the 400 and 428. Did the 428 use dished pistons, lower compression height, or a larger chamber in the head to get the same CR as the 400?
The reason I ask is that I have one #48 head that came to me with a '69 400 HO (code WT) engine in pieces 40 years ago and I am sort of watching for a mate for it. I want to know that I am getting one with the same size chamber. If they are different, is there any easy way to tell which is which without actually cc'ing them?
