Here's my 2014 L77 6.0 Harrop Supercharged V8. Built with forged pistons and rods, mild cam, roller rockers, Higgins heads, and running 11.5 psi boost. Down the quartermile, she runs 11.27secs@129.5mph. Also has built trans, 2500rpm stall and 3.45 ratio diff. Drives great, smooth and quiet. Calais looks stock and a sleeper.
