Helo all i am new to the board.

I might be buying a lt-1 f-body this spring and would like to know what parts are needed to make an lt-1 car run low 13's high 12's all motor. Also a rough guess on how much this would cost. Would 1500-2000 be enough?


Thanks,
Nick

 

Well, assuming you do all the labor yourself, yes it can be done. One of my friends on the board ran a 13.2 with just intake, headers off road pipe, shifter and exhaust. $2000 is plenty enough money to buy those mods. Figure ~$175 for ithe intake, ~700 for coated headers, ~400 for catback (or 40 for cut out if you're cheap) and you've got over $700 left for various things such as a shifter maybe, slicks, a stall converter if its an automatic, even gears.

So in conclusion, yes it can be done.

 

If you have an automatic, get a TC w/shift kit, Drag Radials, CAI, Headers and full exhaust should net you mid to high 12's.

Cost around ~1500

If you have a Manual get gears, DR, CAI, headers, full exhaust, and lots of practice.

Cost around ~1200

These are just estimations though.

whatever you do, plan on buying at least a decent set of drag radials...it is very difficult to launch these cars without spinning too much...

as stated the first steps are the same:
intake, headers and full exhaust and dr

second step depends on auto or M6:
auto -
torque converter and tranny cooler (keep the tranny happy), and probably gears (unless you get the performance 3.23 ratio)

M6 -
shifter and shift light so that you aren't missing gears and are consistent with your shifts.

 

i got it done for a grand

gears $300
exhuast and headers $700



13.2@106...
had the mph for a 12 run too

 

before my gears I ran a terrible et but the mph were a tad over 107. memphis air is good for racing most of the time but our track conditions during testntune suck!!!! with good traction 107mph is good for 12's.

 

What gears would you recomend for a m6? i know the 6 th gear is a major overdrive on these cars so what would you be turning(rpms) at 70 with 3.73's?

 

Maybe a right at 1900-2000.

 

probably about 23-2500 rpms at 70. i am rarely ever going that slow so i couldnt tell you. at 75 i am at like 2700 i think. all i know is mileage didnt change at all surprisingly enough.

 

so the car turnsaround 2700 at 75 with 4.10 gears,not bad. I have a 79' z-28 with 4.10 gears and the m-21 4-speed and i turn 3k at around 55-60 not too much highway driving for me

 

been there to with my old 69 that i had. 4.10's, m21 4 speed, and 255-60-15's meant 55mph 3000rpm and the best sounding drone from a flow that you could imagine. off the subject but that car had a sound that is rivaled by no other, man i miss it.

 

it cost me about $80.00 to run low 13's, Free hooker LT's and y pipe, just had to pay for wires and new plugs, also heat tape.
that is just so cool to brag about !!! Sorry!

 

One word, nitrous , and tires ofcourse.

So for less than $1k, used nitrous setup, low 13s for sure.

 

My friend ran 12.34 (12.42 to win the GM Hi Tech LT1 shootout) with basically this set up:

Shortys/Y-pipe $350ish
GM 4.10s $175ish
CAI $200
1.6 Roller Rockers $300
Hurst shifter $180
ET Streets $300
Moser 12 Bolt $2000

Now, the Moser was a safety precaution as he likes to launch at 5500 RPMs. Don't bother with the 12 bolt, and ease her out at 2500 and you should see high 12s with some practice all for $1500 new (but do like we do and buy stuff used).
