PERFORMER-PLUS CAMSHAFT KIT FOR PONTIAC 350-403 V8

Brand New Edelbrock Performer-Plus Camshaft Kit for Pontiac 350-403 V8 (Part #2157).

Edelbrock Performer-Plus Camshaft #2157 is designed for 350-455 Pontiac V8 engines and produce optimum torque from the low-end to the mid-range. Performer-Plus camshafts should be matched with Performer manifolds for vehicles operating from off-idle to 5500 rpm. The Performer-Plus #2157 is a smooth idling cam for daily drivers, trucks, vans, RVs and 4x4s. You can expect a major improvement in throttle response and torque. In the manifold section you'll find torque graphs showing the power gains from Performer manifolds and Performer-Plus cams. All camshafts include flat tappet lifters (except for cams designed for use with stock roller lifters), assembly lube and instructions. This cam produced 387HP and 439 Ft Lbs of Torque when paired with Performer intake manifold #2156 and Performer RPM cylinder heads #60599.

Installation Notes:

• Recommended Valve Springs for OEM heads: Edelbrock part #5857 non-rotator
• In order for this Performer-Plus cam and lifter kit to be covered under ANY WARRANTY you must use either the correct Edelbrock Sure Seat valve springs or the stock original equipment valve springs.
• Oil/additive must contain Zinc designed for use with flat tappet camshafts.
• Coat cam lobes and bottoms of each lifter with MoS2 lube (supplied) to prevent cam lobe and lifter wear from occurring during initial start-up.
• Do not allow the engine to run under 2000 rpm for the first 1/2 hour. Slow idle speeds may result in severe cam and lifter wear. Start the engine and bring to break-in rpm.
