Hmm looks like you got quite a nice list already. Personally i dont think you could go wrong with boost or nitrous. What compression are you at? If you do to much more i am going to have to step my game up just wish i would have went forged. Good luck with everything.

He is making 460 RWHP 418 RWTQ

C6ZO6's MAKE 435-445 so your car should be a beast... all that's really left is forced induction of some type ...turbo or supercharged if you just want a lot more power 600 to 800 at the wheels and no traction . Me personally i am happy with 491/428 nUmbers that i am making off the stock bottom LS-2

well i dont think id go with 3.73's but 3.91's do seem entertaining! Ive been up in the air over FI or Spray. with the cam that is in the car it kinda puts FI out of the question. I have a bit to much overlap. (<- Someone correct me on this if i am wrong) around a +5 on the overlap math.

The problem with the Gear swap is i have the GetRag rear and would have to have the car down for a few months to get the diff sent off for the proper gear to be installed.
But before i switched Rear Gears i would like to weigh all of my options first. If i went a Turbo route i wouldnt want a 3.91 gear. (do you understand what im getting at)

This is why I created the tread tho, to see weigh the different types of FI/Nitrous/NA setups from someone else's First Person perspective.

I didn't think the 3.73 would make a major difference either untill i made the change i destroyed the stock diff and wanted to upgrade but didn't want to go as short as a 3.91 .Go with a larger short block or stroke your on might be your cheapest option, you are likely to gain 40hp or more on the low side.
