Ok, let’s say it would take either a CAM or a blower to get my truck in the 12’s. If you had to pick one based strictly on reliability for a "tow vehicle/daily driver" which would you chose? I plan to keep the transmission stock but tuned with HP Tuners… this assumes both are tuned and installed properly with the addition of LT headers...Thanks!

Factor in tranny life also...will a properly tuned "stock" 6L80 last longer with a CAM or a blower @ 6-8psi?

 

Blower. TVS.

 

Have you heard more nightmares from CAM'ed only trucks vs blown only trucks?

 

With boost, you can keep the RPMs lower than a cammed setup with less strain on the valvetrain. You can take a stock truck, throw on a blower and a tune and have tons of power with great reliability.

Now take that with a grain of salt, because you can't have power AND reliability forever, there has to be some sort of trade off. But IMO, a mild boosted setup would provide the power gains you want with the best reliability and streetability.

Thanks for the reply...

I hear CAM'ed 6.2's are doing fine ok on stock 6L80's, but that's only 70hp more rwHP...

 

I think it would last longer because again, you won't be spinning the kind of RPMs you would with a big cam. Shifting out at 6500+ rpm is really hard on a tranny.

Either way you look at it, they're both going to be hard on the tranny. Thats just a given.

 

True but you wouldn't get the performance from a cam without a good converter and then you need a trans cooler and the list goes on from there. I would get a good trans cooler and throw on a blower and you can drive normal and never know the difference untill you hit it!

as said before only time will tell on your parts if you add power without upgrading parts, ask me how i know!

 

I didn't vote.

They aren't comparable.
Blower will add torque, cam won't.
For towing, DD and fun the blower will do what you want.
A cam alone will not.
A cam chosen to work with the blower will work better than the blower only.
A cam will not cause your tranny to explode as quickly as adding 120 foot/lbs.

Screw it, do both!

 

There is a guy on the HPTuners boards running 12.4's in an 08' AWD Yukon Denali, just bolt on's and a CAM (stock converter). A good bit heavier than I am... I was hoping the new VVT CAM's help to rid the need of a stall...

Thanks for everyone's input!

It sounds like the tranny would last longer with just a CAM, so what would be more likely to blow up my motor? CAM add or S/C add (6-8psi)?
