382ci dyno #s - 505rwhp/478rwtq I finally got around to rebuilding the motor in the black car (2000 black WS6). After 135k miles, it was burning a TON of oil. Since it was out of the car, why not put some nice pistons, rods, and crank in?? Always upgrade.. never replace!
Specs on the new motor:
- LS1 block
- Mahle -6cc 3.905" pistons
- Mahle rings (1.5/1.5/3mm, std tension)
- Eagle LS1 specific 6.125" connecting rods (ARP 2000 bolts)
- King rod and main bearings; Durabond cam bearings
- Callies 4.00" crankshaft
- PRC stage 2.5 5.3l heads (2.04/1.57 valves)
* coated Comp 921 valvesprings
- Thunder Racing 7.350" pushrods
- Thunder Racing 235/248 .653/.618 112lsa (110* intake centerline)
- ARP head and main studs
- Melling high-volume oil pump (ported)
- Comp adjustable timing set
- Comp OEM replacement lifters
Mods on the rest of the car:
- Whisper lid
- LS6 85mm MAF
- Thunder Racing 1 3/4" headers
- Mufflex 3" y-pipe
- ASP pulley
- Hooker catback
- FAST 90mm intake (ported)
- Nick Williams 90mm throttle body
- Delphi 37lb injectors
- Racetronix 255lph fuel pump w/ voltage booster
- GM Motive 4:10s, stock rear
- Spec stage 3 clutch, steel flywheel
- Full road race suspension (Koni shocks, Suspension Techniques springs, BMR LCA, PHR, 1LE sway bars,etc...)
The car put down 505rwhp/478rwtq with the cutout open. The car needs a ton of tuning (A/F was 14:0:1), so I think it will make an easy 515+ is possible after the tune is done. I was very pleased with the setup considering how mild the cam is (at least in this size motor)! You can really feel the extra torque on the street over a 346ci setup!
Here is a TON of pics of the motor assembly and install:

BTW, stock rear, 4:10s and this kind of power = KABOOM!! I'll post some pics later of the damage! They didn't even last one evening with the new motor. I put some new 4:10s in on Sunday night (midnight) so I could make class at 8:30am!
Geoff@Thunder has his new emulator which makes tuning driveability, idle,etc. much easier! It is really cool to see changes happen in real-time and not having to re-flash the computer everytime a change is made.
So, finally, I have my car back on the road again!
While I had the motor out, I had Allan@FMS go through my T56. It shifts awesome now. It's like I have a whole new car with the new motor, new tranny, and new gears!
HUGE thanks to everyone who helped along the way - Natalie, John, Jonathan, etc... the car wouldn't be on the road without them!

Glad to be the first one to Congrat ya Jason 
This kind of power definitely put ya in 408's high CR N/A territory & considering the A/F ratio there's much more power for that stock rearend to handle hah
if ya have the time post the graph , oh just a few things to ask how much the heads milled & what is the CR ?!
looking forward for track #'s man..good luck !!
peace

Badass Jason. That's some tremendous power for such a streetable package. You've got 427 power at a 383 price! Can't wait to get a ride!

Congrats on the numbers. I'm not trying to steal your thread but I keep seeing great numbers from these type setups. I find these setups more appealing than a 408 setup but the cost is almost the same, why? The cranks I find for a setup like this are so damn expensive. Do they make a budget 4 inch crank?

I went with the 382 because I didn't want to add the ~100lbs to the front of my car with the iron block. Plus, I have built a ton of LS1 based motors for the past 6 years, but only 1 other 382. I just really wanted to try something different and see what I could get out of it.

I'm also curious as to why you had to use 7.350" pushrods. was it due to milling a certain amount off of the heads, if so how much did you take off.
