I find that very hard to beleive. There are plenty of posts on here that would refute this. Also plenty where lower powered Ts out gunned HSVs. With the Ts putting out so much low down grunt, they can usually shame many more fancied competition off the line. Which LS1 is it. If a GTS then 235 wouldn't be far over stock, while we know that 250rwkw Ts are threatening the 12s bracket. Also a 250rwkw T should be over the 600nm mark. As already stated, different dynos on different days, add in driver skills, etc. Too many variables. ← The LS1 was a VX SS with exhaust + extractors and EDIT, possibly an air filter. whereas the T only had an edit with possibly air filter (K&N, etc.) the race was also conducted whilst rolling. vx manual, xrT was auto. This is how I saw the race, but others may have performed otherwise.
