Compression ratio
I have a set of SRP 150723 flat top pistons. They list the compression numbers as follows: 72 cc/11.7 80cc/11.0 84cc/10.1
Anybody have any idea what CR they would make with 95cc heads?
Thinking of using these with Edelbrock 95cc heads for a street build to replace the one I damaged today.

Re: Compression ratio
Just got an email back from SRP tech and they said with 95cc heads CR would be 9.8 to 1.
That doesn't sound right to me?
72 cc/11.7 80cc/11.0 84cc/10.1 95cc/9.8
From 80 to 84 drops compression .9 but from 84 to 95 only drops it .3?
I think he may have meant 8.9.
I guess I'll have to do some cypherin' myself. It makes my head hurt when I have to use Pi.

How did the engine perform? I am thinking of using the above with an RPM Airgap and their Performer RPM juice cam.
