I knew this would end up a pissing match. I tried out a new GTO some time ago, 6.0 6 speed. The manual was hard to shift, at least in a race mode shifting. It was as quick as any small block Chevy in it's class...and remember it is N/A. They aren't going to stay with an SRT6 out of the hole. I have driven both hard when stock... The Goat might, and I say might real back in...but I would doubt it. The only Chevy small blocks that have given me any trouble while T/Ting have been SC'd or TC'd...not counting any Nitrous cars... But, they all do seem to gain some ground after mid track. I hope I am taking care of that problem with the new mods to the coupe. These were all against my roadster....the coupe has yet to see any track time. You have to mod a small block Chevy, just like you have to mod an SRT6 to get any real power out of them. But I will give the nod to the SRT6 out of the hole....stock... 350 Chevys heavily modded...well, they have me mid to late track in most cases, depending on the driver.....
