Aftermarket cams

what kinda number would I expect to gain from aftermarket cams also price

 

I think someone spent a load of money on having custom cams ground and found that it provided almost no improvement because the VVTI on these engines already does a really good job.

If anyone knows of someone else with different results please chime in.

 

Not heard nor read about cams.
Maybe think Super Charger instead.

 

@ViktorG you heard anything about changing cams on the 5.7?

 

Yes, I worked with a custom cam company well before any other aftermarket cams were available and tried 2 different grinds on my NA Tundra with before/after dyno. They did not start making more power than stock until 5800 RPM. If you look at Monkeywrench cams, they say that most of the gains are at 6500+ RPM. Way too high for a most trucks unless you are heavily into racing.
I have not tried cams on my supercharged truck yet, and it now has a 7000 RPM redline, so I will be installing them and dynoing in the next year or so.
Cams on a stock NA truck with a stock redline will not provide any real benefit, and may actually be detrimental to performance in my experience.

 

Hey bud I just saw your post and am about to install a full whipple SC kit on my '16 5.7.
You mention you were about to play with the cams on your s-charged one have you done that and have you posted anything g about what you have found. This kit will give me about 550 ish at the crank and I was gunna try to move toward 600. If I over spin the charger to do this it's going to really try to heat soak the engine since the intercooler provided is very short
