Default Do you think 400rwhp is possible?

I am going to be running a 91 RS Vert with the following

2002 LS1 block
TR 224/230 112 LSA (610 Lift)
TSP ported oil pump
stock 243's with partiot dual golds
comp push rods
LS6 intake (duh)
LS2 timing chain
Long Tubes/cutouts
4l60e with a circle-D 3000 stall
stock 2002 ss rear end (3.23s)?
Custom tune and exhaust


What kind of numbers do you think it will make?
Thanks

borderline 400, maybe 405 if you have a top notch tune.

typical cookie cutter tune....390

Pat G can get you 400 with one of his tunes on that setup.

I've seen M6 cars put down just over 400rwhp with that cam and similar, but through a stalled auto it's going to be difficult. I would guess you'll see in the 380-390 range, but it's not impossible that you might see 400 or so.

M6 would be 400, auto probably 380 or so.

depends on the dyno too. if you WANT 400 hp get to a dynojet. if you want a more TRUE hp rating get to a mustang dyno.

with this setup do I need to upgrade injectors? should I use a ported TB, MAF?
Also what kind of times are possible with some wide DR's?
I've never been to the track in any vehicle so I have no idea...
Just curios. Thanx

I guess the only reason I'm set on getting the cam is because I already have it in the engine... When I ordered it I told thunder racing what it was going in and how much I'd be driving it and the guy recommended this one to me.
Those numbers are def impressive with the bigger cams... Hmmm, well maybe I'll go big in the future, just didn't want to go too big because its a vert and its gonna be driven often, but I've never been in a cammed LS1 car before.

But it seems the tune is very important, I am going to be getting the tune/exhaust done at CMS so we'll see

Doesnt matter who tunes it, a 224/230 cam only, stock manifold/TB car is not laying down 400HP through an auto.

this guy hit real close to 400 on a mustang dyno:

Ryne's dynoDyamic has been dynoeing low but should be real close with a auto
