2004 gto m6 408 stroker

Price: $18000
Mileage: 69000
Private or Dealer Listing: Private Listing
Location (State): IN
Color: Black
Transmission: Manual
Drivetrain: Rear Wheel Drive
LS Engine?: Car has LS engine
The car has 69k (just turned it over) on it. Interior is 9.5/10. It is red leather and red gauges. I dont even think the car has been smoked in before! Exterior is about a 7/10 but ill explain that later. The engine only has 600 miles on it. Compression is 12.26:1 and the car runs on e85. Has ALOT of torque and was built for alot of nitrous!
Bottom end was build at Precision Engine and Machine out of Sleepy Hollow, IL
by Richard Sliwinksi... Upper 700s was originally my goal on spray..and would make that pretty easy
Lq4 cast iron 408 4.030 bore. 4.000 stroke
K1 4340 forged crank
K1 H beam lightwight rods
Wiseco pistons (-5)
Steel nitrited Wiseco top rings (0.22" sml nitros) and cast napier 2nd ring
(0.24" sml nitros)
FM comp main and rod bearing and Durabond camshaft bearing
ARP 2000 rod bolts
ARP Main studs
ARP Head studs
Manton push rods oil restricting 5/16" -.095" wall
ARP balancer bolt
Pro Gear timing set
Victor gaskets
Cometic Head gaskets
LS2 lifter guides
LS7 lifters
Mellings oil pump
SLP underdrive pulley
NGK Nitro plugs
All bearings coated with polydyn
I have every spec on this engine all on paper. If you want to know more detials let me know!
Top end work was done by Brett Land at Landspeed Development out of Indianpolis, In (former Katech employee)
L92 heads with Bretts stage 3 port job
Ferrea hollow stem 2.165 int. valves with flow modified angles (nitrous finish on chambers)
Ferrea 1.600 exhaust valves
Stock l92 rockers (would be a good idea to have the trunions upgraded)
Bullet custom grinded cam 238/250 .643/.620 on a 114 LSA
Patriot double springs (good to .675 lift)
Titanium retainers, locks, locators, and seals
These heads flowed over 370 CFM's!
LS3 intake with Bretts stage 3 port job as well (custom throttle cable holder since the ls3 is originally made for a drive by wire setup)
FAST big mouth 92mm throttle body
K&N fipk CAI
Fuel Support:
72lb injectors from Fasterproms
FAST ev6-ev1 injector adapters
Walbro 255lph fuel pump
This car has been on e85 for almost 2 years now. Stock fuel lines are still fine with no leaks and support this big engine nicely. If you wanted to spray the car you would most like need to upgrade the fuel system to support the e85
Drivetrain:
2006 GTO Differential
Spec 3 clutch and flywheel just installed with engine 600 miles ago
Difftechnics 3.91 gears
BMR drag bags
Peddars urethane differential mount bushing
Exhaust:
1 3/4 Stainless Works longtubes
3" Stainless Works midpipes with high flow cats
Flowmaster catback
Brakes:
Slotted and Drilled rotors
Front bads are still good, just changed the rear pads less than 500 miles ago and have an extra set to go with the car
Visual:
17x 8.5 ADR M Classic's in black (10lbs lighter than stock)
06 black tail lights
Foglights and headlights have blue colored bulbs, not sure of what they are they were in there when I got it
15% window tint
Nitto 555r2 radials out back that need to be changed (spinning at 60 is a little dangerous)
Im sure there is some things im forgetting, there is alot to remember! Like I said before it runs on e85 and it will be sold that way. If you want to change it back to 93 octane you should find a really good tuner since the compression is so high for a street car. The car weighs 3720 even with the cast iron block that everyone thinks weighs your car down so much!
The car made 500/473 at 5000 rpms..from there up it wasnt getting enough air. If it doesnt sell within the next couple weeks it will be getting a 4in harcore intake setup, taking the cats off, and removing the flowmaster muffers. It also needs a catch can due to it being ringed for alot of nitrous. After these changes it should make around 550 or so
Now on to the bad..
The drivers side front fender has a small dent by the headlight. I was told it could be removed using the paintless dent removal but I havnt lookeded into it. Or you can get another fender and bolt it on for a couple hundred bucks
The pinion seal has a leak. I check the fluid every day. I havnt had to put any fluid in it for probably 5,000 miles. A new seal is like $40 dollars tops.
Some scuffs on the back bumper. This car has been a daily driver its whole life, it has the normal wear a 69k mile car should have. The things that need replaced that I listed are easy swaps.
I have 150+ pictures of the engine build and of the car. I have over 12k in the engine alone that is brand new. I realize I wont be getting all of my money back so I think 18k is a reasonable asking price. If you want additional pictures let me know!

Well the car is really restricted right now. It has way too much compression to still have cats and not be running a 4in intake setup. If you opened the exhaust and intake tract up it will still make over 500 on 93. A guy running a similar setup to mine with almost the same heads made 532 and he has less compression than I do. I dont have the dyno sheet or I would post it up.
