906 Heads CC's

[nivvy]

How many CC's is the 906 head??? Im thinking 88

[Chryco Psycho]

88-90cc , they are supposed to be 88 but do vary

Edelbrock has an aftermarket setup with 84cc's...  What's the advantage/disadvantage/idea to this?

84ccs will give you a little higher compression. The Indy 440EZ heads are available with 78cc chambers.

[Chryco Psycho]

the reality is the Eddy head at 84 cc will raise static compression But the heat loss to alum is equal to 1 point of compression Loss so net gain is -.6 compression , to clarify you will lose approx 6/10 of a point of compression in effective cylinder heat so it will act as though you dropped not raised compression

I knew I shouldn't have posted an answer before Chryco. I wish I had half his knowledge and experience.
