well i only have 1/8 mile here but i got a wild hair to try and go 6's on motor, cam only.
stock 6.0 longblock with E-water pump, headers, and pulley.
waiting on my tranny to get here and the track to open up in january.

 

all my buddies are in the 10s cam only on Ls1s and LS2's in the chicago area, but they have weight reduction, etc as well. 10.80s seems to be the norm on these engines.

 

for an LS1, i have heard upwards of 450whp with the T rex cam and weight reduction (3200lbs or less) will go easy 10's.

a 6 liter and the Trex is a proven combo for 450whp or so with LS1 top end intake

capable of 10's yes in a light car

 

I think it should be no problem in a 3rdgen. Arent you close tho?

For me bolt-ons are too expensive, N20 is cheap.

 

i did the 125 shot to get some mid 6's, but im gonna put some real gear in the car. 430>350 and im changing a few things on the car.
ive been 7.17 in the heat one time, and it will run 7.23-7.24 all night in the heat.
prolly too much to ask for, but i know it will go some 7.05-7.09 in cool with the gear swap, but i wanna hope for more.
