This is my first attempt at a LS motor. Have done alot of reading here for the knowledge you folks have.
Heres the scoop :
Car- 2300lb tubeframe chassis built for fast running offroad in the desert. Uses a 5 speed sequential transaxle and big 934 CV joints. Rear tires are HEAVY 35" tall BFG Mud Terrains and heavy cast beadlock wheels(package is about 75lbs per wheel/tire).
Engine : LS2 stock cc's, Mahle flattops with reliefs, H-beams.
TSP 5.3L stage 2.5 heads 62cc's.
PAt G specced 226/232 111+3 cam
Professional Products aluminum intake with some internal cleanup by me.
90mm billet TB, greentop injectors, Delphi MEFI4 computer(speed density)
1 3/4" headers about 24" long primaries, 3" collectors to a single 14" long crossflow Gibson muffler. Dual 4" inlet CBM airfilters(more material than K&N for better fine dust stoppage offroad).
running on 91 octance California garbage gas.
EDIT : I have a FAST 90 that I want to have ported to get on the engine soon.
Here is the dyno sheet - 445hp/399lbft uncorrected, 447hp/400lbft corrected.
