What CC do I need?

[Rickyfin]

Hey all, I've got a 383 bored .030 with KB silvolite pistons in my Charger. Right now, I've got stock 452 heads. According to the pistons, with an 88 CC chamber, I'll have around 9:1 compression. I'm thinking about getting the new Edelbrock heads, but I plan on milling them. I was just curious what CC I'll need to get my compression up to around 10:1? How about 10.5? I read on here that .006 milled = 1 CC, so I can figure it out from there. Anyone know how much the new Edelbrocks can be milled? Thanks all.

you can run 11 to1 with aluminum heads on 93 octane.if you go to prestage.com it was calculators to do the figuring.you will need to know your deck hieght,gasket thickness,and valve relief cc's and add cc's for around ring area(i had 4cc reliefs and added about 3-4 more cc's for ring area) stroke,and bore size.mine is set at 10.8 to1 to be safe.ive got indy s/r not sure on milling edelbrocks.

to get 10.0:1 from a .030 over 383 you need to have a total combustion volume of 88.5 ccs. you will need to measure deck, valve relief, & gasket volume.
