Les, that seems like a lot of timing but I'm am sure I have forgotten what mine runs but will do a datalog with the somewhat slow E/C datalog software. It is in the upper 60* range here in SW Florida and the motor loves it. If I stay V6 I need to find a way to spray water onto the radiator/heat exchanger to cool them down. I still have my catback exhaust to do but from what I mhave read there will not be much gain and I was hoping for .2 in the 1/4 mile. Since I have the parts I might as well have them installed, just need to find a nice tip to fit the Borla's 3" exhaust. I love ther AMG tips. I am toying with the V8 swap, waiting for Jim to get back to me on what is involved. 507HP stock sounds nice but torque is what I am interested in and have yet to see what they made for torque.
I met a guy at the carwash today who had a 5th gen Vette. His car was running so I walked over and asked what his cam specs were, 244*/248* at .050", big cam! I asked what mufflers he had and he said none, just long tubes and high flow cats! Crazy.
