Twin Turbo 99 Camaro with all the amenities Well after 2 long years of work and $$ my car is finally on the road. My previous setup was a 383 with a Hi-flo single T76GTS kit. When I had motor problems I decided to do a setup I've always wanted that would make power. The specs of my new setup are below. We dyno'd it on 4.5# and made 550 and on 9.5# and made 675 so we should be able to make some good power once I turn it up to 15 and 20#.
GMPP LSX block 408"
Lunati Pro-mod crank
Lunati Pro-mod rods
Wiseco 8:1 pistons
TFS 245 heads with 72cc chambers
All ARP hardware
Speed Inc TU3 cam
Mcleod twin disk clutch
Stock T56 with steel shift forks
Moser 12-bolt w/ 3.42 gears
Twin TC67 turbos
Twin JGS400 wastegates
Procharger twin 4.5" intercoolers
Custom Mayhem Motorsports turbo kit keeping all accessories
Twin bosch 420 pumps (1 on a hobbs switch)
83# injectors
#10 feed line
#8 return
This setup keeps the A/C, ABS, cruise control, and even the alternator in the stock location.

The pistons were gotten when I had other heads with smaller chambers. I would have preferred to be at 8.5:1 but these heads and pistons put me at 8:1.
The twin intercoolers are working well thus far and I'll be interested to see how well they work when we crank it up. Yes I'm still on the stock PCM with HPTuners 3 bar.

Nice looking build. I guess would also ask why you only went 408 on an LSX block .Big advantage to LSX is being able to go 427 or even bigger. And yeah 8 to 1 is pretty low for compression but heard different opinions wether it actually can be noticed in everyday driving. I went with 9.5 to one still manageable with alc injection on pump gas.But as you said the combo gave you half point or so lower than you wanted.
Are these six bolt heads as well. Thats one big advantage to the LSX setup.
Anyway enjoy your toy!
