F-body 450rwhp lq9 build ideas?? 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.

Its really going to depend on the dyno, but no I think 450 rwhp is very doable with the mods you listed. Instead of porting the LS6 intake though I'd just buy a Fast instead.

i was thinking of doing a fast 92/92 later on down the road with 225 or more cc heads to give it a great big bump, since i already had the ls6 from my 01 i was going to do a little porting and swap it over. thanks for your insight very appreciated.

Is you "stuck" on using 243 heads ?

Not stuck permanently just working with a budget since all of the build is going to be done at once. I was thinking some trick flow 230s later on with a fast 102/102.....
Somone mention boring .30 over and keeping the stock crank and rods but bigger pistons.
