Advanced Induction LTx CNC Head Porting
This is an inside the machine view of the CNC operations performed on our
190cc & 200cc CNC porting programs for the GM LT1 casting. The actual run
time is hours long, so the video skips forward to give a quick view of most
of the machining operations completed on this particular machine. There
are still many hours in cleaning & preparation, other machining operations,
guide work, pressure checking & other quality control, etc. not shown to
turn the OEM GM LT casting into the most successful GM LTx head to date.
This is the first video we've attempted to stitch together w/ footage from
inside the machine. I hope you guys enjoy it & share feedback, questions,
and requests so we know what you'd like to see in the future. Thanks for

GM's LT1 Engine Explained
GM Powertrain engineer John Rydzewski explains many of the features in the
2014 LT1 Corvette engine, including direct injection, continuous variable
valve control, the rotating assembly, engine block, intake manifold, 11.5:1
compression ratio, and combustion system.
LT1/LT4 Carburator Conversion 350 SBC
I was told this motor would not run on a carburetor. So I decided to prove
that thought wrong and even ran it on my Dyno to show the power it made.
This is the same motor that would be found in the Vette, only it made less
power and was fuel injected from the Factory.

My LT1 7 PSI Procharger 570rwhp ~650hp Trans Am Dyno Run
This is the exact head that powers Rick Abare's 530 rwhp 3440-3470lb
Trans-Am into the 9's at over 138 mph on pump fuel.
My first Dyno run =
~100hp more than expected even the Dyno operator was confused by
wheel spin...:).Much more to be found in this combo only two runs were
made... rest I tuned on I-75!!
3000rpm = 3psi and 420lb/ft with 240hp
4000rpm = 4psi and 480lb/ft with 360hp
5000rpm = 5psi and 517lb/ft with 495hp
6200rpm - 6psi with 495lb/ft with 570hp
The ONLY mods to this 1996 TA are:
200cc LT1 Porting and Cam package
Forged 383 at about 8.9:1
83lb injectors with my own custom 2 bar tune and 2 bar MAP on stock ECM
Long Tube Pacesetter Headers
Magnaflow 3" Cat Back connected to a Pacesetter Y-Pipe (Im sure this is
just killing power).
Single Walbro 255l/hr pump.
McLeod Street Twin with Alum Flywheel
Everything else (as in.. the entire car) is fully stock including the
Traction Control and AC (it still works) and spare tire (and amps and
So, this car is HEAVY, and ran 124mph in the 1/4 mile. The ZR1 might run
132mph and is about 900lbs lighter.. so YEP that just about confirms HP.
