1989 IROC 408 T56 12 Bolt
Decided to post my car up to try and get into something different. Only trades I would consider are G-bodys in good shape, something with a big block or something with an LS.
I bought the car in 2007 with a bad motor and could probably dig up over 20k in receipts mostly for parts. Here is the run down:
Body in good shape with no rust and clear title - Garage kept.
-KTRE 12 bolt rear, 4.10 posi C clip eliminators 31 spline axles Moser girdle (all under 3000 miles)
-17x11 and 17x9.5 zr1 polished wheels with like new tires; nitto drag radials out back.
-spohn lower control arms with rod ends (adjustable)
-BMR adjustable panhard bar
-jegster adjustable torque arm
-aluminum driveshaft.
-bolt in subframe connectors (welded in as well)
-interior in good shape with new headliner, jegs beige buckets and mint dashpad.
-accel super stock coil
-aeromotive A340 in tank pump
-hooker 1 3/4 longtubes
-full 4" mufflex exhaust with spintech muffler
-skulte longtube crossmember for t56
-stock replacement radiator
-megasquirt 2 with msextra code
-MSII relay board and wiring harness.
-southwest speed power steering pump and braided AN plumbing
-holley stealth ram intake
-line lock
Poly bushings in stock A arms
all new steering linkage
new ball joints
lakewood 70/30 drag shocks
-408 2 bolt (less than 500 miles since assembled by burtonsville performance machine)
ARP main studs
ARP head, intake and water pump bolts
eagle cast crank
I beam eagle rods
probe forged dished pistons (10:1)
edelbrock performer rpm heads
howards hydraulic roller cam
proform 1.5 roller rockers
holley stealth ram powdercoated gloss black
30 lb accel injectors
Custom cold intake with K&N
msd pro billet distributor
msd 6al
Stewart warner aluminum water pump
chrome 1 wire alternator
billet alternator bracket
billet pulleys
-1996 T56 6 speed
Recent rebuild (less than 25k miles, shifts great)
spec stage 3 clutch (less than 500 miles)
centerforce flywheel for 400 engine and t56 (cost almost $500 new)
Quicktime blowproof bellhousing
pro 5.0 shifter
Car runs and drives really well, have not made any passes with the current setup but the old setup went bottom 12s, leaving soft (1.8 60 ft.) and granny shifting. Only difference was a little higher compression.

cold start:
Tune is currently very conservative (total timing under 30 degrees.)
Asking 9,000 OBO
Thanks!

Just installed a new Holley 58 mm billet throttle body and 89-92 style cable which makes the car very easy to drive. Line lock has also been wired to an existing switch in the console.
Will post motor and interior pics soon.
Drove an hour each way to the track on Sunday and it ran 11.98 at 115, using et street drag radials, granny shifting with the muffler on it.

ttt - willing to hear offers
-The mini starter grinds sometimes, but I have another powermaster that I can swap in.
-Window motors have gotten pretty slow over the past couple years.

Add 300 miles to the estimates above as it has been driven some since then, Nittos are just to the wear bars, fronts are still good.
I will be getting an alignment and tires balanced within a week or so.
