GPI LS2 / LS3 3-Bolt Cam
These cams are our most popular product, and for good reason – they are pound for pound – the best cams on the market for your LS2 or LS3 using L92 / LS3 rectangle port cylinder heads. These cams have become the benchmark for 5th Gen Camaro’s and C6 Corvette’s all over the country.
Our GPI Camshaft and Head packages have been dominating race tracks, and taking 5th Gen Camaros & C6 Corvettes 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 camshaft – from mild performance increase with nearly stock manners, to all out N/A race applications.

Only improvement I recommend is to include valley cover options in the kit. I had to come back and get that.
