2007 5.3L 56hp gain!
 

A big thanks to KBRacing, Stock48, and Mitch at Total Engine Service in Lubbock, TX! I installed the Triple 12 cam and gained 56hp over baseline on an otherwise stock 5.3L in a NNBS Crew Cab. Truck mods listed below:

3" in/out Dynomax Ultraflow muffler (stock manifolds)
PRC .650 dual springs (stock 243's)
Comp double row timing chain
K&N air filter
Katech oil pump shim
Built 4L60E
DOD Delete
Trailblazer Stall

The dyno only shows 4900rpm due to vehicle speed being at 125mph. This cam makes great usable power up until 6200rpm. Next up to install is KBRacing's intercooled 70mm front mount kit.

That's a pretty good gain, add a turbo on top of that and you will have one heck of a groceries getter!!

Got any videos?

Great gains from that cam, it doesn't take a huge cam especially with FI.

Video? Also how was mileage affected? Congrats, that's a nice gain!

Nice job! Thanks for sharing, and that is usable power under the curve that you can feel. Didn't even get close to it's pk power point. That cam pk's around 5600-5800 rpm in a 5.3L.

How is the low end?

Real Nice!

Impressive!

Wow. I need to get one of these? Did u get it right from stock48?
This is the same triple 112 cam all over this forum?
Doesn't make a diff if I have an 09 5.3?

Nice gains, can't wait to see the boosted numbers

Dang, real nice gains!! I'm also interested to know if this is the same triple 12 that everyone uses, and for boosted results. I don't remember seeing to many NNBS crew cabs that are turbo'ed, very interested in that.
