Default 1991 Corvette M6 - No longer for sale.

I've decided to sell my 1991 Corvette M6. This is going to be a little long, but here's the scoop...

I had a 1992 Z28 autocross car and I decided I wanted a street car. I pulled the engine out of the Z28 (approximately 1,200 miles on it since it was built) and bought a Corvette. I put a set of Trick Flow 175 heads on it and a TPIS Miniram II as well as a TPIS throttle body and did a complete teardown and refresh before putting it in the Corvette (rod/main bearings, had the crank polished, new cam bearings, all gaskets and seals, new heads, new intake, new throttle body). I bought a Canton road race pan for it, stainless works long tube headers and a Dewitt radiator and started putting it together. The transmission was converted to crash through and a Hurst shifter was installed. I also ordered all the weather stripping for it and changed some (the rest is in a box) as I had time. It also has a new center console lid and new sun visors. The heads, intake, clutch, flywheel and distributor have about 40 miles on them, the throttle body and injectors are less than that and I installed the Borla kit last weekend....it's brand new). I've paid for two proms from two reputable places and I've been working on cleaning up the tune and some driveablility issues and I'm finally tired of spending my time and money tuning it and not driving it. So...I'm listing it for sale. I have a pile of money in this car, I'm asking far less than I have in it and I'm not looking to go much lower on it. I don't have to get rid of it, but I think I'm going to go C6 shopping and send this to a good home. I'm selling the car and the collection of parts I have for it as a lot.

It's red with black leather and has 117 k miles on the chassis and a 6 speed with 3.45 gears (dual power seats, electronic climate controls).

I'll save time and just start a parts list:

350 bored .020 over with splayed main caps and two bolt studs (and a billet front bearing cap on the #1 main)
Forged crank (ZZ3 crank)
Lunati Street Race rods (5.7") with floating pins.
KB Signature Series 12cc dished pistons
Speed Pro plasma moly file fit rings
zero decked, torque plate honed and line bored.
Clevite bearings
Melling oil pump
Cloyes double roller chain
Comp cams 220/230 .510/.510 cam (114 lobe separation)
Comp roller lifters
Comp pushrods
Comp Cams chromoly 1.52 roller rockers (7/16" studs)
Moroso aluminum valve covers with a screw on cap TIG welded on
Trick flow 175 heads (10.49:1 counting decking, head gaskets and all)
ARP 7/16" rocker studs
ARP head bolts
ARP header studs
ARP oil pan, timing cover, etc bolts
ARP Pro series flywheel bolts
ARP harmonic balancer bolt
Jegs billet aluminum distributor hold down
TPIS Miniram II (1205 gasket)
Accell 36 lb/hr injectors
TPIS 58mm throttle body
Davis Unified ignition HEI distributor
MSD gear reduction starter
MSD plug wires
ATI lightweight aluminum Superdamper (3 ring, road race version with aluminum shell)
Aluminum adjustable timing pointer
Stainless works long tube headers (with air system removed and the holes TIG welded closed)
Cat delete pipe (bolt in using a band clamp on the front and the stock ball and socket rear flange)
Borla cat back (installed last weekend)
DeWitt 1.5" fabricated aluminum radiator
Hurst shifter (gearbox was converted to crash through)
Walboro 255 lph fuel pump (Racetronix kit)
Goodyear hoses
New power steering hoses and remanufactured pump
Alternator was replaced last month (reman from a parts store)
2 piece under drive pulley set
Edelbrock water pump
Fidanza aluminum flywheel
Centerforce dual friction clutch
New 275/40-17 Sumitomo summer tires (40 miles on them)
2 total sets of sawblades (3 painted)
J55 brakes (on the car)
Spare ECM
Spare drive axles (rear, aluminum)
4 U joints for the rear axles (still in boxes)
New U joints in the driveshaft
Non crash through shift shaft from the ZF gearbox
Brembo "Sport" brake pads (on the car, and a set new in the box)
Metal Master brake pads (in a box)
New strap kit for mounting the rear axle U joints (still in a box)
Dana 44 clutch rebuild kit (new in the box)
Monroe Sensatrac shocks (40 miles on those, the shocks on the car had lost their oil and these were put on as a temporary improvement until I got it tuned)
Hypertech chip (came with the car, included with this package)
Accell 36 lb injectors
A box of weather stripping (the stuff I haven't installed)
Both tops (tinted and body color)
JVC in dash DVD player with hands free/bluetooth and Rockford rear speakers (fronts are in a box, I never got time to install those)
Hurst shift ****
AC has been converted to R134 (but I was planning to change it back to R12).

I'm sure there's more and I'll go through the garage and update this. I'd rather find someone who wants to finish the tune and enjoy it instead of parting it out.

So, in a nutshell, if you like tuning these cars and want a car with a lot of nice stuff in it and a bonus shortblock as well as 3 sets of wheels....look me up.

Pics on request. And I own the F-body road race autocross forums (www.frrax.com), there is a thread on there about the Camaro (that I had this engine in) and a thread about building the Corvette with some pics where you can see what's where and what's in the car, etc.

Located on the west side of Columbus, OH.

I wanted to update this to say that it's no longer for sale, I have a complete FAST XFI 2.0 kit for it and I'm going to convert it over to a FAST system and go from there. That should fix the tuning issues. I'm going to rewire the engine and try to adapt the rest.
