Compression Ratio? Gen iV L76, 799 heads I purchased an aluminum 6.0 from a guy who worked for a chevy plant. He said he pulled it out of a wrecked Trailblazer SS.
The block is an L76, heads are 799 casting. Pistons have valve reliefs.
DOD and VVT were there but we deleted them.
I converted to Vette acessories for a D1SC Procharger in my swap.
Just trying to figure out my compression ratio now.. Can anyone help?

With the valve reliefs and the heads not milled, then ~ 10.6:1 on stock gaskets. Chances are if its the stock Pistons that were flycut, then the reliefs are probably only 1-1.5cc.
