Why is everyone so afraid of running a simple 2 hose GM dry sump set up? Tanks are readily available and you get lots of extra reliability from the system especially if your planning on pulling some LATERAL Gs with the finished build. I have a 09 Z06 Vette running it up to redline puts a big smile on my face. LS7s do have a reputation for some reliability problems, there were rocker arm failures in 2007 build motors and it seems there were some mis machined rocker mounting pads on some motors. GM has a warranty check for excessive valve guide clearances and my buddies machine shop has done 4 sets of LS7 heads in the past year and a half for the Chevy dealer. Nothing wrong with the output of a stock LS7! Check the C6 Z06 section of The Corvette Forum for LS7 technical information.
