What should the compression ratio be? Can anyone tell me what the compression ratio should be on a 408 with -12cc reverse dome pistons and 70cc (L92) head chambers? and what the compression gauge should read with a VTC-3 cam set up at a 105 ICL, with that compression?

With a GM MLS gasket and assuming your pistons are 4.030" bore and zero deck you'll be right about 9.9:1 static.

Yea, with the .051" gasket it's a tad closer to 10.0:1, but no big deal
