Its running full sequential fuel and COPs, spec is :
5.4L by V8Developments
Top hat liners.
Cross bolted, Tufftride treated and polished block.
Bespoke High Grade Forged Aluminium Pistons.
H-Beam Steal Con Rods.
Each component matched in weight then dynamically balanced.
V8D Stage 5 cylinder heads.
Compression ratio 10.5:1
45mm Inlet manifold and Trumpet base.
440cc Injectors
LS2 COPs
Helix Padle Clutch.
Lightened and balance flywheel.
Twin wideband lambdas
8 x EGT probes
Hit 350ft/Lbs of torque on the dyno at 3100RPM before the bench dyno slipped!! So should be 350+ BHP and 380+ Ft/Lbs
