Motor is a Virginia Speed built LS2 447ci Stroker. It made 583whp on a break in tune through my GTO with 3.91 gears and a 4000 stall. It went 6.29@107mph with a headwind the only time I took the setup to the track. Motor has about 300 miles on it. I bought a CTS-V and I'm parting out my GTO.
$5500.

They are about -3cc ( 2.8cc to be exact ). They are also domed, so they are really built for hogh compression setup. With 74cc heads, it is around 11.2:1 static compression ratio and 12.3:1 with 65cc heads.
