Can I beat LS1's or LT1's yet?

LT1 is way slower then a LS1

LT1 ran from 93-97
LS1 ran from 98-02

LS1 has way more power up top compared to both and has alot more power!

Stock vs Stock?

Most Stock LT1 ran 13.8 to 14.5 and traps around 98-102 Depending on drivers

LS1 Usally Run low 13s all day and have been known to run a 12.7 straight from the factory! Been done but didnt happen much... and trap at about 105-107 if i remeber correctly?
 
There was an F-body with at least an aftermarket exhaust at the 1/8th last thursday only running 9.4 - 9.3 @ around 77 (that was several runs)... Thats what I run with just basic bolt ons... You should be raping the LT1's with a blower...
