My opinion: yes. Doing a cam kit is a lot of money and I personally would not want to waste anything or miss out on potential power. Will it be harmful or hazardous? Probably not (someone else can answer). Will it be less optimal? Yes.

I also suggest calling whoever you are planning on buying your cam from (especially your tuner assuming you are taking it somewhere to be tuned) and ask what kind of losses you could expect. From my experience, they are usually vary helpful

 

I cannot speak for all the supercharger kits, but the Magnuson is specifically designed to be installed on a stock engine, and it is those parameters that they can give such good warranty. If you are seriously considering supercharging you need to investigate into that. For the record the Magnuson works extremely well on a stock 5.7 cam. Ry

The factory cam profile has no impact on the design and application of the aftermarket supercharger, aside from any canned tune they may provide.

That said, a cam profile specific to being used on a forced induction engine will make more power, provided it is tuned.

OP, there are a lot of variables that go into choosing a cam. I would call some cam companies and pose that question to them.

Maybe consider waiting until you can do both at the same time since some of the labor will be redundant.

 

cams for forced induction will have less valve overlap vs. NA applications

while a NA cam can work for a forced induction setup, the version for less overlap would have better results for power and torque curves

and why have to re-do the job again, since it would require pulling the heads, new lifters and all that

@lieu910 The quote below is just a part of what Magnuson will discard the warranty regarding, that was my point.

ALL COVERAGE WILL BE DENIED IF THE DAMAGE TO THE SUPERCHARGER SYSTEM
IS RELATED TO OR ARISES FROM OR OCCURS DURING NON-INTENDED USE, INCLUDING THE:
Use in an application that is inconsistent with the stated catalog application
Use of any components or assemblies that are modified from or substituted for original items, e.g., drive pulleys, fuel injectors
Use of incorrect or contaminated fluids
Use of engine modifications, e.g., oversize crank pulley, aftermarket camshaft, etc.
Use of methanol, alcohol, or nitrous oxide systems
Use of the vehicle in any form of racing or for performance competition purposes
Use of fuel with octane rating less than 91 octane ((r+m)/2 method)

Magnuson sticks their neck out to cover the additional 3 year warranty based on it going on a stock engine. But anyone can toss the warranty out the window and do whatever you want.

 

I just went with a 6.2 cam with my maggie kit. Definitely work up the 5.7.

 

 

I think Engine Master did an episode debunking SCer cams.

Yup but is was a small block Ford.

The Great Blower Cam Debate - Engine Masters (Season 5, Episode 25) - Apple TV

The guys put claims about blower cams to the test with their new 363ci small-block Ford.

I run a Comp Cams 274 cam with a Whipple and 10lbs of boost, not a lot of overlap on cams for VVT engines.
