These cams are our most popular product, and for good reason – they are pound for pound – the best cam on the market for your LT1 engine. These cams have become the benchmark for 6th Gen Camaro’s / C7 Corvette’s.
Our GPI Cam and Head packages have been dominating race tracks, and taking 6th Gen Camaro’s & C7 Corvette’s deep into the 10 second range for customers all over the country.
Although these camshafts were designed with naturally aspirated motors in mind – because centrifugal blowers maintain a very similar, linear power curve as NA – these cams work beautifully with centrifugal blowers. Great option to keep in mind if you are naturally aspirated now – but are later planning on adding boost.
We have 5 different iterations of this very popular cam (and the option to do a custom spec cam) – from mild performance increase with nearly stock manners, to all out N/A race applications.

Works well with the stock torque converter, offers stable idle, excellent low end torque, and smooth lobe design for quiet valve train operation and longevity. We designed this cam for use in cars with minimal modifications. Idles stable around 675 RPM, and is very strong off idle to 6800 RPM. Works well with 3000 + Converters.
Tailored for the street/strip individual that runs a 3000+ RPM converter. It rivals the torque output of the SS1 but packs on about 10-15 additional horsepower up top. Strong to 7000 RPM. Converter recommended 3000 minimum, 4000 plus for max performance.
This is our most popular street / race cam, and for good reason. This is the perfect cam for the hardcore street / strip enthusiast, and makes more torque and horsepower than our SS1 and SS2 cams. Very strong to 6900 RPM. Track tested, developed, and proven! This cam requires 3600+ RPM Converter.
Our LT NFC requires no flycutting when milling the OEM heads .040″ and running a .040″ gasket which puts you around 13:1 compression! The increased compression is required with this camshaft! Works with Holley Hi-Ram Manifold, Holley MSD Manifold, and the GM LT2 Manifold!
This cam, with our ported OEM heads, milled .040″, .040″ gaskets, and a Hi Ram Manifold, in a 6th Gen Camaro weighing about 3600lbs went 9.90s in the 1/4, and made over 590 RWHP!
All out performance application. Very street able, requires 4000 plus converter. Track tested and developed 10 second cam with heads and supporting mods. Strong to 7200 rpm.
12.5:1 compression minimum, ideally 13:1. Will require flycutting for adequate piston to valve clearance.
All out performance application. Very street able, requires 4500 plus converter. Track tested and developed 9 second cam with heads and supporting mods. Strong to 7600rpm with correct valvetrain setup and High Ram manifold.
13:1 compression minimum, ideally 14:1. Will require flycutting for adequate piston to valve clearance.
