LSX 454 crate motor
11:1 Compression
LSX LS7 GMPP heads
GMPP 4150 Carb style intake converted to TBI
Aeromotive Fuel Rails
Kenne Bell BAP
FIC 60lb injectors @ 3bar
Kooks 1 7/8 Primaries - 3" Y pipe no cats
4" custom exhaust from Y pipe back
4" FWI
NW 102
LS7 MAF
Zex perimeter plate(just sold my nitrous kit though so I wouldn't be tempted to spray)
6061.com 4150 elbow
LS1 Efan conversion
Front mount trans cooler
Shiftrite Tranmissions built 4l70E
Circle D 3200 Stall
Pretty basic crate motor setup. If I had to do it again though I would have went with a LSX 427 custom setup because I limited myself with where I can go from her kinda. I'm getting the boost bug and want to boost this setup but the LSX standard deck 454 doesn't leave a whole lot of wall thickness. Some say that this motor should not be boosted at all. While I think that aiming for like 14-16psi is nuts a conservative 6-8psi will net good gains and still keep her together. The cam is the basic GMPP cam but this thing has a nasty lope and does not sound like a street car at all. This motor will kill your stealth 100% lol. Anyway I'm either gonna port the hell out of the heads and get a different cam and keep her NA or leave the motor alone and boost it haven't decided yet but I have time I still have to finish off paying for this end of the project first.
