**REQUIRES FLYCUTTING**
GPI Stage 4 Gen 5 LT1 N/A (Naturally Aspirated) Camshaft Specs (SS4-LT): 233/257 .639"/.639" 112 LSA
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.
From GPI:
"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."
