LT1/LT4/L86 GPI PD1 CAM DURATION 218/246 LIFT .639"/.639" 116LSA
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 725 RPM, and is very strong off idle to 6400 RPM. Requires 0* phaser limiter.
