New and Hot! LT1 Performance Parts!
CNC Heads, Hot Cam Kit Expand Capability of Chevy’s Gen V Small-Block

Introduced more than 60 years ago, the Chevrolet
Small-Block is the benchmark performance V-8 engine.
The fifth-generation of the iconic overhead-valve
architecture is the power behind today’s Chevy full-size
trucks, the Corvette and the all-new 2016 Camaro SS.
In the Corvette Stingray and Camaro SS, it’s known as
the LT1, and at 460 horsepower it’s the most powerful
standard engine ever offered in both vehicles.

Chevrolet Performance is proud to announce a new CNC-ported
cylinder head and an LT1 Hot Cam for the engine to
give builders and enthusiasts the capability of coaxing
even more power from the high-tech V-8.
The new LT1 CNC cylinder head (P/N19329839) offers
greater airflow capability from ported intake and exhaust
runners. It comes fully assembled with the valves,
valve springs and retainers; and is designed as a direct
replacement for the original LT1 cylinder head.

Chevrolet Performance’s new LT1 Hot Cam (P/N 19303897)
builds on the legacy of racing-proven camshafts for
Gen I and LS-Family Small-Block engines, enabling the
LT1 to increase airflow capability across the rpm band.
It is designed for off-road use and to perform optimally
with the Active Fuel Management cylinder deactivation
system disabled.

A new valve lifter kit (P/N 12648846)
includes eight conventional lifters to replace the eight
specialty lifters in the LT1 that support Active Fuel
Management. There’s also a new valve lifter guide kit
(P/N 12595365) to go with the new lifters.
For the ultimate LT1 performance upgrade, Chevrolet
Performance offers a comprehensive kit (P/N 19333535)
that includes a pair of the CNC-ported heads, the Hot
Cam, lifters and lifter guides. Tuning is required with all
of the components to achieve optimal performance.
Off-road use only. Tuning calibration not supplied by
Chevrolet Performance.

The LT1 is driving Small-Block performance into a new
era and with Chevrolet Performance, you can get even
more from this modern classic!
See page 271 for complete details.
NOTE: Installation of this kit will affect engine variable valve timing
and Active Fuel Management operation. Recalibration is required for
accurate engine operation (not available from GM).
(See page 35 for important warranty information)

All-New Performance Parts for Your All-New Gen 6 Camaro!

Thanks to an all-new, stronger, stiffer and lighter architecture as its foundation, the Gen 6 Camaro is more capable
than ever. In fact, with more power than its predecessor’s V-6 and V-8 engines, the Gen 6 Camaro accelerates
quicker, turns with greater confidence and brakes harder to deliver new benchmarks in performance.
Of course, true performance enthusiasts are always looking for an edge in performance and profile, and Chevrolet
Performance is there with an all-new lineup of components and systems designed to make the Gen 6 Camaro pull
even harder, stop even shorter while looking – and sounding – even better doing it.
From performance air intake and exhaust systems, to lowering kits and even performance brake systems, this new
lineup is sure to distinguish your 2016 Camaro on the street or at the track. Like all of our new vehicle components
and accessories, each is factory-engineered and validated to production-vehicle standards, so you can be confident
these upgrades will look, fit and perform like original equipment.
There’s never been a better-performing Camaro and with these new performance accessories, your Gen 6 will offer
even more!

I wonder how much HP they will advertise with the heads/hot cam combo.

"Off road use only" on the hot cam. I wonder if it will trip any emissions lights or if it will make it through an OBD2 scan.

I know the more aggressive h/c packages with supporting mods are getting to the neighborhood of 550 rwhp pump gas on the lt1. But that's near max effort on stock cubes.

Historically the hot cam is a smallish cam and it's hard to say the gains from ported heads might be minimal.

Just a guess with full bolt ons I would put this kit in the neighborhood of 480-500rwhp. Total guess for a semi aggressive h/c build lt1

Has anyone made an aftemarket intake and throttlebody for the lt1 yet?
