Well...I am hard on cars I went through 3 factory trannies and 1 built one. Preston has busted a built one also. As for F-Bodys having more power yes they do does that mean they are faster? No. Every LS-1 I raced with the Mach I was giving up 50+rwhp from a roll and would stiill win. A dig would have been ugly. Should that happen? No. 4:10's does wonders in a 4 valve. I am not hating on LS-1's I like them a alot my girl has one I drive it everyday its an 01 SS M6. Stock for stock its a drivers race but like I said before who in the hell has a stock car? AJ- I seen some of those links you posted I love Z06's I almost bought one instead of my Cobra those times are good. But those are the guys that LIVE at the track for example Ranger is a good driver and runs his cars like 3 days a week as many times as he can. lol. Which is what you have to do to pull those times. Perfect everything air,da,etc. For instance Cody had LT's and no cats on his Z06 made 370rwhp and he was going 12.50's at 115 and when he sold it to Garret he was going the same and they are good drivers thats on street tires. I could post link after link of 03 Cobras pulling crazy time but I'm not crazy about track times.....there is Pullied only Cobras running 10's and Ported ones running mid 10's at 130+ not bad for a "Tank" and very cheap mods.
