Hello all, Good to be a part of the community.

As the thread says I'm going with an Lq9 iron block for my Fbody Camaro.
Looking to do mid-max effort n/a and a 100-150 shot of nitrous as a cherry on top later on. Searching for some experienced advice/suggestions as to what i can make/build that won't be overkill on the wallet. My initial idea was big cam full bolt on supporting mods. rundown below:

6.0L lq9 iron block
ported ls6 intake/tb-port matched to heads
mild ported 243 heads dual springs -maybe bigger valves? Full Cnc?
1 7/8 headers-cutouts and 3inch straight dual exhaust
244/242 612/610 112LSA camshaft
underdrive pulley

Am i heading in the right direction looking to get 450-460ish on a dynojet though a fbody m6.

All ideas and recomendations welcome, as well as constructive criticism this is the second engine I've modded the first was a h/c/i ls1 i made 429.9 on a dyno jet with the 6.0 being a better platform hoping for an extra 30rwhp. Thanks all in advance.

Why the reverse split on the cam? Especially with N2O down the
Road, I would go +8* Minimum on the exhaust.
Actually that cam is very large for 360" and is just starting to
Come on as the intake and heads are just about tapped out!
236*/244* would run Much Better on the street, Definitely
Have 243s CNC Ported!
Mamo Ported Fast 92, worth 18-20 over ported LS6, Ported 102
25+, will be tough to get 450 with LS6 intake IMO.

So you wouldnt do a cam that big on a 6.0.....was thinking perhaps .30 over and make it a stroker build stock rods and crank opinions on this?

Bore .030 to 370" great idea!
Stock crank & rods is not a Stroker.
4.00 Crank with aftermarket rods & pistons is a 418" Stroker!
Then you need better heads and bigger cam.
You could keep stock crank & rods bore .030 = 370"
Sell 243's & LS6 Intake.
Buy MMS 220's out of the box have Tony port a FAST 102
put a small CAMMOTION 231*/235* .620"/.600 cam
With LSA determined by Tony, Kip, Pat, or Martin and
Make 500+ RWHP with fantastic street manners and rip your
Head off throttle response and pull to 6500+ RPM.
THE "HAVE YOUR CAKE AND EAT IT TOO SCENARIO"!!
Would outrun a 418 with CNC 243's and a big cam.

370 sounds like the plan.....lets say i keep the ls6 and 243s with some port work what kinda number would u say thats good for?

NAVYBLUE210

Quality CNC Heads AI, ETC will help allot, LS6 will really choke it down,
You will need a pretty good size cam at least 236* intake duration
With at least 8* more exhaust especially with N2O, you might get
450, I would guess 440 depending on all the details.

Some trick flows are on the bill later with a fast 102/102 this is th e beggining

TEA does a nice 243 2.5 with lightweight turned down LS3 valves
With good springs that made 470 RWHP in a LS2 with 227*/234*
cam, FAST 92, all the details in the Dyno results section.
