Default Going for MOAR power, new motor and MOAR goodies! gen IV 5.3 & tc78

Popped the old iron block 5.3 on the dyno last go around, broke a ring land on piston #7. So naturally its time for an upgrade

Here was my old setup-



And here is the upgrades in the new setup
-gen IV aluminum 5.3, uses the newer LS3/LS2 components and should be a stronger motor, also dropping 100lbs on the front end couldnt hurt
-Cooling Mist boost activated deluxe kit with their super atomizing injector and solenoid upgrade
-Patrick G custom ground cam 22*/22* 60*/60* @ 115+ 4
-Deatsch Werks 96lb injectors
-Deatsch Werks Fuel Pump
-96mm Maf Housing
-LS3 Maf

Other Info-
-Ported/ Milled 317 heads should be around 9.7 CR
-Fast 92/92
-TC78 turbo, custom with a 3.5 " downpipe and a .96 a/r
-ls7 Lifters

Just got the motor dropped in, waiting for my new front cover to come in so i can finish assembling everything







Its been a learning process on figuring out what all i needed to make this Gen IV motor work. but i think i finally got it all figured out

any shots with the hood closed? My charge pipe is roughly in the same spot, just wondering if it sticks through the top of the hood, or if you had to notch the underside of the hood. Just a quick pic of how mine is setup.
