Capable of 12s?

Is it possible to get into the 12s without any internal engine work.

Mods are gonna be the following

4.10s or 3.90s whichever ratio works best
Pacesetter Coated LTs
CAI
Cutout
Madz28 Tune
315 Drag Radials
TB Bypass
Weight Reductions

maybe i'll add some Roller Rockers, but i'd like to stay away from a cam on my 110K mile engine.

Is it possible?

Maybe with some suspension work?

Car is a 6spd also.

with suspension work and gears, I would say yes. My car ran a 13.7 in stock form, so w/ drag radials, prolly 13.5

with bolt ons, prolly a 13 flat, idk.

Id say u can get extremely close, and some1 will mention it
there have been bolt-on cars run low 12s/high 11's i believe

With those mods, is it possible? Definitely. It will take some good driving though.

Definitely can, It all depends on the weight reduction... The bolt-on LT1 record is 11.805 @ 113.96, and that is currently held by Shon Herron...

I am hoping to loose a few pounds in my pig over the next few years, and try for it myself, but I may get bored and up the power with H/C before then though if it doesn't look like I am getting close...

Of course that was half bolt on and half bolt off. LOL

4.10s for sure
LT with 3" duals
CAI
Tune
Sticky tires
52mm TB and bypass
Some skinnes and salad shooters out back to lighten the load
Roller rockers and new valve springs are a good idea
A little weight reduction and 12s should be easy

12's with no internal mods is very possiable. My car when it had just a CAI, 2800 stall converter, 3.73's and DR's went a consistant 13.2xx @ 104.xx. I could have very easily gotten in to the 12's with no internal mods, but I had heads/cam sitting in the back of the car so I had to throw them on the car.
