Full exhaust (meaning LTs, ORY with good Y-merge, 3" catback/cutout or true duals) plus a lid should make around 400 flywheel horsepower with a tune, on a perfect running otherwise stock LS1.

Cool. I figured everyone would assume I was talking about rwh. Just asking because every time someone asks me how much power my car has I say 350hp. (rwh) and they say "thats it"? lol I think non car people are always assuming you are talking about power at the flywheel.

Same here, when I was telling people what my truck was making at the wheels they always have a dumbfounded look on their face, "Isn't that less than what they have stock?". Also love the people that don't believe cars are ever under or overrated.

Yep, they dont under rate them at all. Thats why my 325bhp ls1 car did 308rwhp stock. People arent the brightest bulbs in the box.

Yep, 243s and an LS6 cam are more than bolt-ons for a 4th gen F-body.
