engine plus heads
 
Hi, anyone know what the cc are on the engine plus heads.

Not exactly, but why is this so important? Anything can be made bigger or smaller right?

Stock its pretty large (65cc or more iirc) as they are meant for 103-105 bore (stroker) engines with the resulting bigger then usual capacity.

I need to start having the cylinders cut, I want zero deck height. I will be going for 8 compression

Just do it! Actual measuring of the heads themselves (the ones YOU will use) is always neccessary to set the exact CR you want though.
On a high end engine you cannot use generic values, but thats obvious right ;-)

I now have measurements that I can set thing in motion. I have been jogging between wanting a EZ-36D, only if I could have installed it under the deck lid. I don't see where it possible. So, I am having my cylinder shortened in height by .125. I went to CB's site and used their calculator. Everyone says to keep static compression around 7. However I also have heard that at 7, the engine can be gutless. Even though my I had my cylinders made, I chose I believe 6075, with a heat treatment.

I need to have these cylinders cryo treated and Nikisil treated. Given that I tried to add as many fins and lower my fan pulley ratio, I hope the 8 compression will hold up under one atmosphere of boost. I unless I here more on the 3.6 Subaru, I'm back on my 3 liter type IV.
