The best cam for a 454 big block depends on the engine underneath the valve covers and the job the vehicle does. For a confirmed Chevrolet Mark IV 454, the Edelbrock Performer-Plus 2162 is the more conservative starting point here; the Performer RPM 7162 belongs on the shortlist for a deliberately matched performance build. Both are hydraulic flat-tappet cam-and-lifter kits. Neither is a universal replacement for every engine sold as a 454.
This shortlist compares manufacturer specifications and installation requirements. It is not a dyno test, and the recommendations do not promise a particular horsepower increase, idle vacuum or emissions approval. Identify the block generation, cylinder heads and existing valvetrain before ordering.
Compare the two Mark IV 454 camshaft kits
| Camshaft kit | Best starting point for | Duration at .050-inch lift, intake/exhaust | Listed valve lift, intake/exhaust | Main limitation |
|---|---|---|---|---|
| Edelbrock Performer-Plus 2162 | A milder build prioritizing low-to-midrange operation | 218° / 228° | .500 / .500 inch | Requires a verified flat-tappet installation, compatible springs and proper break-in |
| Edelbrock Performer RPM 7162 | A matched performance engine with supporting head and valvetrain work | 240° / 246° | .560 / .573 inch | Substantial supporting requirements; not the default choice for a heavy work vehicle |
The manufacturer’s application summaries identify Mark IV big-block engines. These recommendations do not establish Gen V or Gen VI compatibility. Listed lift is a specification for the intended rocker arrangement, not a guarantee of clearance in your engine. Sources: Edelbrock 2162 specifications and Edelbrock 7162 specifications.
1. Edelbrock Performer-Plus 2162: the milder shortlist choice
Edelbrock positions the 2162 for lower-speed use and describes a smooth idle. Its 114° lobe separation and shorter duration distinguish it from the 7162. For a Mark IV owner whose priority is everyday drivability, it is the first of these two kits to discuss with an engine builder. That is a selection judgment, not a claim that it will suit every truck, compression ratio or fuel system.
What you get: a hydraulic flat-tappet camshaft kit with matching lifters and assembly lubricant. Springs and a timing set are separate purchases. Edelbrock’s instructions specify using the supplied new lifters. They allow appropriate stock springs or Sure Seat 5862 springs, with installed height checked for the actual head and spring arrangement; worn original springs should not be assumed serviceable.
- Why choose it: it has the less aggressive specifications of this pair and a documented cam/lifter combination.
- What to budget for: spring inspection or replacement, timing components, gaskets, oil and installation labor.
- Where to be careful: its instructions discourage high-volume oil pumps and require attention to distributor-gear condition. A catalog compatibility label does not replace an engine-specific check.

2. Edelbrock Performer RPM 7162: for a coordinated performance build
The 7162 has substantially more duration and lift than the 2162, plus a 112° lobe separation. Edelbrock lists a 1,500–6,500 rpm operating range. Treat that as the cam’s advertised application range, not permission to spin any stock 454 to 6,500 rpm. The kit contains one camshaft, 16 hydraulic flat-tappet lifters and assembly lube.
The 7162 instructions call for modified or performance heads, screw-in studs, adjustable rockers and matching valve springs. They specify 5762 springs when using stock heads and explain that stock umbrella seals need a different seal arrangement. Rocker-slot clearance, spring setup and piston-to-valve clearance need to be checked.
- Why choose it: it is a defined option for an engine being built around a more demanding cam, rather than a cam chosen solely for its sound.
- Main tradeoff: the supporting work can cost much more than the kit. It is not a simple stock-valvetrain swap.
- Intended-use limit: Edelbrock’s Performer RPM guidance specifies at least 9.5:1 compression, appropriate heads, headers, gearing and a performance converter for an automatic. It excludes heavy vehicles from this cam family’s intended use.
Those broader requirements appear in Edelbrock’s 2019 catalog, printed page 128; this is older manufacturer guidance, not a newly issued specification. Have Edelbrock confirm the complete combination against the instructions supplied with the kit. Also ask it to resolve the downloaded 7162 manual’s conflicting timing-set numbers before purchasing the timing drive. View the Edelbrock 7162 kit.
What to check before choosing a 454 cam
Start with the actual engine. Record the block and head casting numbers, generation, compression ratio and current cam/lifter type. A vehicle’s model year or a seller’s “fits 454” label is not enough, particularly after an engine swap. Edelbrock also excludes 1965–66 big-blocks that require a grooved rear cam journal. If you have a Gen V or Gen VI engine, or want a roller conversion, obtain a separate recommendation for that combination. Do not order one of these kits on displacement alone.
Describe how you drive. Give the builder the vehicle’s weight, transmission, converter, axle ratio, intake, exhaust and normal rpm range. Heavy towing and a lighter performance car are different jobs. For a work-oriented build, start the discussion with the milder 2162; choose the 7162 only when the supporting combination makes sense.
Price the whole installation. Ask for a written parts list covering springs, retainers, seals, pushrods, rocker geometry, timing drive and any machining. Confirm clearances and spring pressures instead of assuming that a component called “performance” is compatible. Both kits use flat tappets; they do not convert an engine to roller lifters.
Plan break-in before the engine starts. Both exact manuals prescribe cam/lifter run-in and include an additional warning to use suitable break-in oil or zinc additive. The stated run-in speeds differ between the two manuals, so follow the instructions for the exact kit and obtain clarification if the supplied paperwork differs. The assembly-lube tube is not the separately required break-in oil.
Check the vehicle’s emissions requirements separately. Mechanical fit and “computer compatible” wording do not establish legal road use. Confirm the specific combination and intended use before purchase. No road-emissions approval is established by this shortlist.
Which kit should you choose?
For a verified Mark IV 454 and a moderate build, start by evaluating the 2162. For a performance engine with the required head work, adjustable valvetrain and supporting drivetrain, evaluate the 7162. If you cannot yet identify your engine or provide its specifications, the best next purchase is a properly planned parts combination, not the largest cam on a list.

Frequently asked questions
Will either camshaft fit every Chevrolet 454?
No. This shortlist is limited to confirmed Mark IV applications. Gen V, Gen VI, swapped engines and altered valvetrains need separate compatibility checks with the cam manufacturer and engine builder.
Are the 2162 and 7162 hydraulic roller cams?
No. Both are hydraulic flat-tappet cam-and-lifter kits. Use their specified matching lifters; neither kit is a roller conversion.
Which of these cams is the better starting point for a mild build?
The 2162 has the milder specifications of the two and is the first one to evaluate for lower-speed use. Its suitability still depends on the engine, vehicle weight, gearing and intended work.
Does the 7162 work with an unchanged stock valvetrain?
Do not assume so. Edelbrock requires a matched performance installation with screw-in studs, adjustable rockers and suitable springs, plus checks of seals, rocker clearance and piston-to-valve clearance.
Can I reuse my old lifters with a new camshaft?
These Edelbrock instructions require the new lifters supplied with the kit. Follow the exact kit’s lubrication and break-in instructions, including the separate break-in oil or additive requirement.
