Features Of Your New BTR Camshaft

The BTR LS3 Stage 4 V2 camshaft is an aggressive street / strip cam with a very tough idle!

This camshaft is designed to make great gains throughout the mid-range to top end & suits the addition of nitrous!

This cam produces a very lumpy idle with the numbers to match!

This grind requires a hi stall converter.

NOTE: You cannot mill the heads when using this cam without causing piston to valve clearance issues on a stock bottom end.
