That sounds mean. Any details on the motor other than displacement?

Here is his exact response he gave me on Instagram a while ago. "Building the ls4 383 high compression E85 and nitrous forged internals."

Obviously a cam, worked 799?? heads, headers, custom true dual x-pipe exhaust.

As badass as that is, i just cant justify any more money into a FWD v8 application. Traction is already a big enough issue with these cars, and dont get me wrong I love my car, but sooner or later you gotta face facts about whether its worth it to throw money at a dead platform.

Yeah I hear ya. As awesome as that car is, I could never justify throwing that much money into my gxp. Ive debated finding a low mileage used ls4 to replace mine which I am having lifer tick and possible beginnings of rod knock not to sure though, and since Im going to need a new trans anyway I would pull the motor apart, dod delete and cam swap since it would be out of the car.... But that would just make no sense seeing as Im looking at getting a ws6 in a year or a bit more. Shaun's car is a huge sleeper though and will likely hurt many more feelings than it already has

any 5.3 LS crank stroker kit will work you just have to machine the ends to the LS4 10mm fronand 3mm end. and notch the required portions in the block.
