Default 400rwhp/tq from LS6/LS2
What bolt ons does it take to make 400rwhp/tq corrected with stock longblock through an automatic trans with an LS6/LS2 based motor in an F-body or Vette?

Thanks

Nitrous. It's a bolt-on, right?

Can it be done with stock H/C/I using just bolt ons like full exhaust, UD pulley, CAI/filter, TB & tune or do you have to use a cam?

Thanks

Mods in my sig through an M12 manual Transmission.

The aluminum flywheel is what put me over 400rwhp (or at least is what makes it show 400 rwhp due to less mass).

You are not going to get 400rwhp out of an LS2 with bolt-ons only. The strongest LS1 bolt ons are making around 350rwhp, you are not going to see 50 more rwhp out of 18 more cubic inches. You will at minimum need a cam.

220 to 230ish cam + headers + tune and you should be fine.

What's the max HP/TQ you see with bolt ons only (stock longblock and intake) with a LS2/Auto?
