What makes a 2 liter?

[jdbubb@ix.netcom.com (Dan Bubb)]

1st. Are you guys talking about an 8V or 16V. If it's an 8V then the
compression doesn't change by sticking a 2.0L block under a 1.8 head.
2nd. The comment about squish area doesn't make any sense. Please define
squish area so we all know what you think you're talking about.
