Compression ratio?

Post  XC460Coupe on December 12th 2014, 7:39 pm

I'm trying to get a rough idea of what comp my combo might have, 460 + 30th speed pro forged pop ups milled flat with single eyebrow relief, D20E-A heads but not sure on finished deck height. Comp test shows 180 psi in all pots. I realise I won't get an exact figure just a ball park. Any input appreciated. Cheers Tim.
