Vortec 4.3L 90 degree V6 Engine Upgrades

 
L35 HO Roller Camshaft for 96-05 L35 and LF6 4.3L V6

Part Number 1X262001

$459.95

This roller cam features lobe profiles similar to the famed 350 ZZ3 V8 camshaft. The exhaust lobe lift was slightly reduced to allow use of the stock 4.3L valve springs and net lash rocker arms. The L35 HO cam raises the power peak from 4400 rpm to 5600 rpm. With this product you can expect gains of at least 25 horsepower on L35/LU3 engines and as much as 40 horsepower on LF6 engines. We recommend a low-back pressure cat-back exhaust system and our L35 HO engine computer recalibration for optimum performance.

 

 
L35 HOT Roller Camshaft Kit for 96-05 L35 and LF6 4.3L V6

Part Number 1X262002

$559.95

This roller cam features lobe profiles similar to the famed HOT V8 camshaft. The higher valve lifts of the L35 HOT cam require shortening the valve guide height and the use of the included L35 HOT valve springs and retainers. The L35 HOT cam raises the power peak from 4400 rpm to 5800 rpm. Expect gains of at least 35 horsepower on L35/LU3 engines and as much as 50 horsepower on LF6 engines. We recommend a low-back pressure cat-back exhaust system, higher stall torque converter, and our L35 HO engine computer recalibration for optimum performance.

No modification is required to install the heads or retainers. We recommend a low-back pressure cat-back exhaust system and our LS6RV engine computer recalibration for maximum performance.
