L83 Cam Swap

Evanski9 · February 27, 2015

Looking to get this done.

From what I read you get some decent power gains off the new DI

Interested if any one has done it yet.

I am interested as well and haven't found much info.

I will continue my research and see what I find. I sent a emailt to Texas Speed to see. Looking into a mild cam. Looking to keep the low torque and gain a little bit up top.

Guy doesn't say what cam he is using though. Put down crazy good numbers though. According to the video description it made 408 rwhp 386 rwtq.

lol yea, they are pretty sick. Truck has a great stance and the Nitto Terra's look great too.

Bolt -on's cam and tune are getting solid numbers in the 400 RWHP and torque range. I saw a you tube of a Black 2014 Lowered RCSB Sierra that had CAI, Cam, Head work and it was in the 410 Hp range i think...but I cant find the damn video now.

This one?

No it was a Black Sierra. I will try and look for it.

EDIT: Fastlane performance did a Dyno with AHR cam,heads and pulled 419HP and 399 Torque. It has nitrous but wasn't used on the pull.

I saw Comp Cams make 3 different grinds for the gen V DI engines. I read an article on a swap in a new LT1 Vette with the biggest cam. It also needed the VVT limiter, new valve springs installed and a custom tune. If there's enough cam swaps out of vettes there should be factory LT1 cams out there for cheap that would be more of a direct swap for the L83 without messing phaser.

Sorry about the double post...

Comp cams and Lingenfelter both have cams available for the LT1 engine. For example in my 6.2L/L86 comp cam has 3 options and Lingenfelter has 4 (2 supercharger cams and 2 NA cams). My truck stock dyno'd at 350rwhp/380rwtq. According to my tuner with a cam I could expect another 80 to 100 at the wheels.

I have been doing alot of research. Looks like many are going to give you a mild lope, which is not a bad thing. But I am guessing can get annoying in a daily driver.

Yeah...but wait till the young guy with his ricer civic and girlfriend pull up to you and smoke em'! I for one think these trucks are very un-assuming in the power category.

Why would a mild cam be annoying for daily driving?
