Default Is 400rwhp and 400rwtq possible w/ stock heads?

What cam to acheive this?

2002 WS6
6 speed
long tubes
true duals
ls6 intake
SLP air lid

Would a 228/232 110 LSA or a 227/233 111 LSA get me there? Also, what about the "El Torro" cam. Anyone have any numbers with it?

it's definitely possible, but to achieve it you might need to go with a bigger cam. throw an UD pulley in there and pick up an extra 8-10 rwhp easy.

I would like to see if anyone just achieved 400rwtq with stock heads, gaskets, and compression.

Milling the heads and using thinner gaskets would make 400rwtq cheep and easy but is a lot more work than a simple cam swap.

You're running a 227/233 cam, right? How do you think it would be on a 110 or 111 LSA?

those are impressive numbers to be cam-only with only some of the bolt-on goodies. my cam just went in this weekend and is getting tuned tomorrow, so i'll find out exactly what i'm making. i think 400 may be a long shot with my mod list but who knows

I made 400/400 with stock 241 heads, LS6 intake, P&P TB, 1 3/4 LT, 6spd on a 10 bolt.
Cam was a TR224 224/224 .561 .561 on a 112 LSA.

So it is very possible.

'02 Trans am with Hooker LT's, TD's, stalled auto, 4.10's, UD pulley, K&N & TB, 230/230 .612/.604 110+4 LSA. Made 390 rwhp and 380 tq on a mustang dyno. Through a 6 speed I think it would have hit your goals.

EDIT: I don't think it makes a difference but my T/A was one of the f-bodies that got a LS6 block
