This BTR camshaft and valve train kit includes the well-known LS3 Stage 5 Camshaft, BTR 0.660 Lift Dual Spring Kit. Whether your project involves turbocharged, supercharged, or naturally aspirated setups, BTR offers numerous options, all supported by years of expertise, knowledge, and a dedication to power.
This cam is not for the weak at heart. Intended for use as a MAX EFFORT NA style cam, in combination with ported cylinder heads, while also using an aftermarket throttle body and intake manifold such as our Trinity series intake. Best results when using a 5" cold air intake tube set up. If you're wanting brutal mid range and top end power, these are this camshaft's shining attributes. We've seen power figures North of 600hp on our engine dyno in a SBE application when used in conjunction with BTR valve train components and a short runner intake manifold.
Note: This cam requires fly-cutting when using OEM pistons, but the extra labor is key to obtaining maximum performance from this combination. However, fly-cutting is NOT required on a L99 engine with exhaust notches. Higher than stock stall converter and lower gearing* (when applicable) is recommended along with an E85 compatible fuel system.
*Notice, Valve spring kits upgrades and Pushrod options available, see the product options to configure your system and avoid any delays!
*Custom tuning is required after installation. We offer remote tuning options see here or we recommend going to a local dyno shop near you for custom tuning. Camshaft Specs
