BIG CAMSHAFT VS SMALL CAMSHAFT: You won't believe the power difference!

I think a much more interesting "test" would have been to change everything else on the car to make it work with the cam that was already in it, lol. Then you would have seen some gains!

That would be a good test. But I think his point was, someone put a Big cam in there without matching other important and expensive parts and the car ran just as it should have, like crap at low RPM's. Bucking, surging etc...
This was the fastest and cheapest fix to make the car run crisp and clean on the street. Oh, and it made more power in every way...
There's plenty of These types of cams in big build cars that make way more power, but apples and oranges. Oh, and Money

Agreed, then swap in the small cam. Would lose power up top but may still run the same at the track (sometimes even better) since there may be more avg hp throughout the rev range.

I'll agree everytime cause it's what I preach. Keep saying it cause some still don't get it.

I was thinking that, too, just to illustrate that you can also under cam a car.
You think, even if every other aspect of the car was designed to work with the big cam? Gear, tire, heads, compression, intake manifold, TB, exhaust... everything. I guess we really don't know the specs of the big cam, so maybe it's not even worth talking about. I guess it's possible that it was just too big and never would have worked in that car, but I kind of doubt it.

I'm still going with the stock ls6 cam and making way more power than that thing with appropriate bolt ons.
A better question may be why does erryone think a bigger cam is super magical and instantly change out the oe cam?

I was at the road course last year. A guy had a C5 vette. I took a lot at it and realized it had a LS6 intake. After looking closer it was a Mallet Corvette. The car had a 240ish duration cam and it idled like ****. Back in the day, that was a 30K engine. People have found combos that work better.
A 240 duration cam needs rpm to make peak power and probably will make peak at 7000 or higher depending on the intake. For a street driven car, a 224-228 duration cam can rev past 6000 and still be easy to drive.
And low dyno numbers don't mean squat. It might be a stingy dyno. Some people brag about dyno numbers but some of the numbers I've seen are way overinflated.

Can someone please do a cliffnotes of the power difference and cam specs? My computer speakers died at the house, and if they worked I don't have the patience for a 25 minute video lol.
But I'll take a guess that it made 10-20 hp difference at over 6k roughly and the smaller cam drove better and they liked it more. Probably faster all around too since there was more average hp/tq.
I used to love racing dudes with cams with my bolt on car. Spanked a ton of them because everyone thought the biggest cam you could fit made the car the fastest.

Big cam in a otherwise stock engine is a good way to go slower.

I was one of thee idiots back when i had my 2005 GTO. I put i donkey dick cam in and it was horrible vehicle to drive in any kind of stop and go. I am also sure the tune wasn't the greatest on top of it. It actually kept me from driving the car. I was so happy to get that cam out of the car. And just so you know the guy in the video Andrew is one of the best tuners around.

Exactly why I chose a Ws6store hot cam for my bolt on only car. The big cam route sucks, I've done it.
Cam advertising reminds me of pro golf players advertising 10 yards more with an off the shelf club that they would never really use. In the game of 10hp and driveability it's not worth it.
But the big thing was that torque gain vs the big cam, not hp. That was most impressive.
