It's between 9.5:1 and 10:1.
A compression test with stock cams came out with 225-230 across the board.

Here's the numbers I used.
Bore: 3.426
Stoke: 3.937
Head: 46
Gasket: .045
*Deck Height: .0001
Dish: -13
Num Cyl: 4
CR=9.9:1
*Deck height needs to be negative since the pistons slightly come out of the bore, but the ROSS calculator doesn't support that.
I'd like to get the static CR down to around 8:1 (8.5:1 max) so I can run more boost on pump gas.
