I'll agree with all the folks saying it'll be a drivers race. Come on folks,,, how many times have you seen a crappy driver pull 14s in a LS1 or even a new Cobra??? I've seen plenty. There is only going to be 2-4 tenths between them at most if both cars are driven well. IF,,, {and a big if} both drivers are good and it's on the strip,,,, maybe the nod goes to the LS1,,,,maybe just by a smidge.
Most LS1s run low to mid 13s with a decent driver {I ran a 12.96@108mph with only a lid}. So far, the average for Mach1s around here seems to be pretty much the same, just a smidge slower. Figure mid to high 13s on average with a great driver getting low 13s. I've seen around 20-25 passes from Mach1s this year, most were upper 13s.
Pecking order right now goes- new Cobras coming in at around mid to high 12s,,,, LS1s coming in at low to mid 13s,,, Mach1s are running mid to high 13s and GTS are turning low 14s for the most part. JMO,,, sound bout right?
00Z28 {or whatever your name was},,,, how bout shutting up? You are making it hard for the rest of us that like all cars. Automatic LS1s had 3.23s for the most part, manuals had 3.42s.
