Re: [Amc-list] V8 Cylinder Head Questions - Follow up



I've got a follow-up to!!
Just found this note in PAS -- "Amount of milling required to reduce 
chamber volume 0.16cc - 0.001" (for any chamber size head).

The change on the 304 was from 9.0:1 to 8.4:1, a 0.6:1 compression 
change. Change was 0.5:1 on the 360. So you're looking at roughly a 
half-point change. As long as it stays around 8:1 you will be fine. The 
local machine shop can give you a rule-of-thumb about how much shaving 
it takes to get 0.5 points compression back, I forget!

*** ADDED FOLLOW UP ***
  How much would compression be raised if the 52.2 CC 70-71 304 heads were installed?  Just curious.  Stock 360 is 58 CC for my 1989 GW.
