My son has a 2002 Camaro Z28 (305 HP/LS1) Automatic. The ONLY mods are180 Stat,Early Hypertech Programmer, SLP Air Cleaner/Box 3.73 gears.

It runs 12.8 @110 at Sea Level in Summertime and is still under GM Extended Fact Warrantee.

It weighs around 3800 as raced ( 200 Lb. Kid/ 250 Lb. Dad)

Your Corvette is Several 100 Lbs. Lighter and has better Exhaust and some other Power Improvements ( I think).

My Stock 94 Vette ran 12.69 @ 111 at Sacramento in 1995 at Div 7Bracket Finals (Runner Up) Hypertech/160 Stat./KN/3.7 Gear.
At that time a 308 Lb. Driver and full tank of gas (Stock Goodyears). It was around 3500 with me in it I would guess and I understand
that the LT 1 is a bit slower than LS 1 Combo ( You GM guys could tell me ).

The gears in both Car made a HUGE Difference (Seven Tenths in Camaro with a 2.72 to 3.73 Ratio Change) but I think the gear
change is more difficult in the newer Vettes. My 2006 Ran 12.40s@ 113 at NHRA World Finals(2010) a couple years ago with a 2.59
gear and stock Goodyears, Gears and Drag Radials would make a Big Difference!!

If you change gears and engine is in decent shape you will be fast enough! E Mail me if you need more Info but Beware of my

GM Knowledge.................I am Mopar Guy and just bought my cars just to have the Extended Warrantees on my Bracket Cars.

HOPE this helps I do not Race Pure Stock (NHRA West Coast Boy).......The '94/'02 still get 22 MPH on road with 373 and OD auto!
