LT4 Short Block & Halltech CF CAI
All parts removed at 6000 miles from 2016 C7Z. Went with a Procharger and LME 416.
C7Z Short Block (can include stock camshaft if wanted) $3500
Halltech CF CAI with nomex sock (does have holes for meth nozzles that can be plugged) $1000
LT4 info:
Rotating assembly – Each component of the rotating assembly is unique to the LT4 to support the cylinder pressures the boosted engine is capable of generating, as well as the unique requirements for a lower compression ratio. Elements include:

LT4 info:
Rotating assembly – Each component of the rotating assembly is unique to the LT4 to support the cylinder pressures the boosted engine is capable of generating, as well as the unique requirements for a lower compression ratio. Elements include:
- A 1528MV forged steel crankshaft with tungsten balancing inserts, ground pin collars and intermediate pin drills for rods 1-6
- A lightweight, forged 6061 aluminum damper with a T6 anodized hub and an iron inertia ring (the LT1 uses an iron damper)
- Lightweight, high-strength powder-metal steel connecting rod design for reduced reciprocating mass and quicker rev capability. It has the same balance mass as the LT1 rod, but a higher load capability, with features including machined lightening slots and additional lightening features, as well as a “stepped”/wide pin end with a premium bushing
- Forged aluminum pistons with flat top crown that supports the 10.1 compression ratio and internal ribs for strength (similar to the LS9 piston design). A premium ring pack includes a PVD-coated top ring, chrome-coated second compression ring and a nitrided oil control ring – all for exceptional wear resistance and durability under high cylinder pressure. The bottom ring land also features eight oil drains
- Floating piston wrist pins with a durable diamond-like coating for durability and low friction
