i havent taken mine to the track yet, (its a long drive).

I was just wondering what you ppl are running after the swap, any idea what i should be running?

84 trans am
3250lbs 3440with driver
02 ls1/t56
slp loudmouth exhaust
k&n
crank pulley
power trax locker with 3.73 gears
subframe connects, edlebrock torque arm and panhard bar
tubular lower control arms
toyo ra1 255 tires

im just getting ready to do a buildup with poprted dart 225 heads, cam, ported fast 90 intake with nick williams 90mm throttle body, hawks headers, a cutout, fast fuel rails....ill have to upgrade my rear end.

 

If you can get it hooking I'd say you'd run 12.7 ish at around 107mph with your current set up. If you can really get it launching HARD your not very heavy so you might do even better. With the package your thinking about ( make sure you cam it accurately ) I'd guess 440 rwhp is within reach and that should net you some deep 11's at 120ish MPH

 

yea, thats what i was thinking, high to mid 12's, but the trap speed seems low, also the buildup im doing should be higher than 440rwhp, the dart heads are ported, and im having my fast intake ported, the previous owner of the heads made 505rwhp, my set up will be differant but im still hoping to get at least 460

 

505 N/A out of a 346 cid LS1??? thats damn impressive post up what you make I'm curious

 

same time as befor the swap (central)




















just kidding I never got it to the track. only raced a few cars so I can't say what it runs. low low 13's and high 12's seem to be the common ground with the basic swaps and or gears
