*Note: For 1981-89 applications.
**Note: Some engines may have .010'' oversize diameter lifters, check for white paint markings above lifter bores indicating their use.
***Note: 1985-91 Chevrolet 90° V-6 262ci (4.3L) engines have a different firing configuration than the 200-229ci engines, and cannot use the 200-229 camshaft. The 1987-91 262ci (4.3L) engines are equipped with hydraulic roller camshafts have a stepped nose like the LT1 engine and require a different timing chain set and use a different configuration camshaft core than all the 1985-86 engines that were produced with flat tappet cams and therefore cannot be interchanged. The 1992 and later 4.3L engines incorporate a balance shaft which necessitated a third timing chain setup to drive both the cam and balance shaft. These also utilize a different camshaft core that can not be interchanged with previous models. Most Chevrolet 262-400ci V-8 valve train components are applicable to the 90° V-6 engines.
LOW AND MID-RANGE TORQUE AND HP, GREAT CHOICE FOR CARS AND 4X4 TRUCKS, HIGHWAY OR OFF ROAD. WORKS REALLY GREAT FOR TRAILER TOWING.
