Although it's something I probably wouldn't do(unless I experience an engine meltdown!), I have to admit that I'm loving the creative nature of this build! I wanted to bring up one thing that I don't think has been mentioned or discussed yet. Although this engine swap has dropped some weight out of the rear end, It probably has moved what weight is back there much higher up in the car. Going from a flat 6 to a V8 has got to raise the polar moment of inertia, and there for increase the possiblility of drop throttle oversteer, which our 996's are prone to in the 1st place!...not saying that this couldn't prove to be an entertaining by product of the build
, but would be interested to hear your thoughts on how the car has changed on the handling dynamics front White Out. I can't recall if PSM was an option in my99(I have it on my00), but if yours did have it, are you still able to run it?
Congrats, and great job on the build!

Thanks!
I don't have PSM. As an ex-Viper owner, it's a plus to me.
It may have raised the center of gravity, but I suspect that it wouldn't be noticeable. The heads are aluminum and the intake is plastic, and there isn't much in the heads for a SBC. Also, I had to remove the sound deading at the top of the engine bay to fit the LS1; cut the trunk, and remove the adjustable wing motor and engine bay fan. Realistically, it's probably a toss up.
As far as widowmaker characteristics, the low-end torque will easily spin the 295 tires where the G96 wouldn't break the 265 loose. So yes, at the track I am going to be very aware of snap oversteer. My torque figures are in the same range as a GT3RS4.0.

Here are some updated pics.
For some reason the exhaust looks angled down, don't worry, it's not. I still have to remove the residue from a sticker that was on the decklid.

Well not for failure, just poor quality:

There is a class action for everything!
This was an awesome science project and super impressive build work. Congrats and thanks for sharing it! Extremely interesting

Some recent updates:
1. Changed the coolant system layout a little:
- removed thermostat from electric water pump
- created a T so the coolant overflow directly feeds the coolant system by gravity vs. feeding off pressure.
It looks like crap, but will work for now:
2. New tires came in!
3. Created a new switch panel for engine control, starter, and coolant control. Replace the factory CD holder.

when is the next YouTube clip...
if my engine ever goes down 1 of 2 things will happen.
A) I make a b-line for the GM dealer for a new Stingray (red with gun metal wheels and GT3 seats).
B) I put one of these Chevy engines in it.
I'm not sinking big bucks into another Porsche engine. Or I'll buy an air-cooled Carrera for very light driving..

nice build.
Most of you guys don't relieve that the lsx will shift above 8500 with not to much done to it. I use to shift at 7100 on my stock ls1 and now shift at 7600. I could/would spin it harder if i wasn't already over spinning my blower. I also make 1270hp on a 5.3 lsx truck block with blower on 87 octane.. So i guess we could do the match per liter on that.
If i ever have an issue with my motor, there are no questions what ill be putting in there. They are simply to cheap and to reliable not to do.
