I'd like to know if I will (or should depending on the driver) be into the 12's in the 1/4 with my combo. If not, what else do I need ?
Also, I'd like a guess to my FWHP and RWHP.

 

Oh yeh, youll definitely hit 12s if you get some traction, and you should have over 330rwhp id say, getting some long tube headers would help, definitely rear gears if you dont have them, good luck and let us know how it goes!

 

I currently have 3.42 rear gears; 4.10's are not an option for me as I drive 120mi+ round trip to work every day with this car !
I could go with 3.73's, but I have heard they are not worth the cost over the 3.42's as the gains would be minimal.
I can't go with a full long-tube header because I need the stock ground clearance (once again the 120+miles per weekday over typical lousy Michigan road condtions)

 

well if you have 3.42s it wont make that much of a noticible difference, just alittle in the times, lts arent that bad for clearance but whatever you want to do man--good luck just get some good tires/wheels

 

If ground clearance is all thats holding you back on Lt's I wouldn't sweat it. I too live in MI with the mods in my sig and have yet to bottom out my exhaust.

 

I agree with all above you should easily be there maybe even 12s on crappy street tires depending on driver...

 

You'll be in the 12's for sure, I managed a 12.55 with a 1.97 sixty with stock shortblock, stock heads and a cam.

 

12.97 with current mods in sig.
