What's my compression ratio going to be?
 

If I use .028 gaskets over the stock .050, and mill the stock LT1 aluminum heads down .020.

I used an online calculator and got 11.8:1, but thought that was off.


Thanks for the help.

You'll need to know head CC's, piston CC's, deck height, bore, stroke, and head gasket thickness to know for sure. Using stock specs and your .028 gasket I get 11.2:1, but without knowing your engines exact specs I'm just guessing.
