LS9 cam, beehive blue springs, GEN4 timing cover, 3 bolt 4x cam gear, harness adapter, lifters, gasket set, anything else needed? will ecm tuning be needed right away?

Asked by STEVE on December 12, 2017

Ran this in 2013 camaro with no tune, temporarily you will be fine.

BERNIE from OK answered on December 14, 2017

Cam sensor in the front timing cover unless youre getting the timing cover kit thats including it already and itll idle and run but it will need the tune so it can run how it should

ERIC from TX answered on December 28, 2017

THis is just a stock replacement cam pretty much I just sent mine back thought it would be upgrade

CHRISTOPHE from SC answered on December 17, 2017

Only use the 4x gear w 58x crank. 1x gear w 24x crank, will need to be tuned. This cam is an 85 whp improvement, timing and fuel will need attention.

NATHAN from WI answered on December 15, 2017

Thats all you need and Yes you will need tuning or you will be running rich and can cause harm to your motor.

Will the stock lifters work with this cam? I know there's a limit to how much lift on the cam you can run without the stock roller lifter link bars will hand before it bind up. I have a 2001 5.3 & a 2007 4.8 I'd like to put this cam in.

Asked by MICHAEL on October 30, 2017

I HAD THIS IN MY 2006 SILVERADO 5.3 AND THE STOCK LIFTERS WORK JUST FINE NO ISSUE.

MARIO R from SC answered on October 31, 2017

I'm running this with stock lifters with no problem in a 5.3

ROY from IL answered on November 07, 2017

Yes they will work. I always recommend replacing stock lifters though.

ZACH from MO answered on November 23, 2017

Stock lifters will work on this cam in both engines. Also stock lifters in these engines do not have link bars.

Will this fit my 00 Chevy Silverado v8 5.3 ?

Asked by RAMON on April 01, 2018

Yes

BERNIE from OK answered on April 03, 2018

You have to upgrade to the front cam sensor

JOHN W from CA answered on April 03, 2018

Yes it will fit, it will require replacing the timing chain cover to replicate the cam sensor to the front.

JASON from GA answered on April 03, 2018

Yes but you will need to upgrade the cam sensor to the front swap out the cam sprocket and get a new timing chain cover with the pig tail.

I have this exact cam. I see people asking if this will work on their 5.3 with 862 heads provided they change their valve springs out as well. Does this apply to a 4.8 with 862 heads and/or 317 heads as I have a set of each. Also I would like to run a forced induction system as well, more than likely turbo setup. Any info would be greatly appreciated.

Asked by ROBERT on August 24, 2017

This cam works great in a boosted 4.8.

NATHAN from WI answered on September 16, 2017

U can run on any ls swap just make sure u have a front timing cover sensor and the right sprocket for yoir ecm early model need half moon sprocket. I belive this cam does not support a rear sensor

OSCAR from CA answered on September 10, 2017

I use this cam as my budged friendly turbo cam ... beside the fact that it has great manners for the daily drive it works great with just the ls9 springs or the pac 1218 in the case of boost the 4.8 will be great on 862 i dont use the 317 bellow 10psi of boost

URIEL from TX answered on September 07, 2017

Yes you do need to change your springs I ran the ls6 blue springs with my setup

Do yourself a favor and grab one of these if you are on the fence about what to get. You are also going to need a valve spring upgrade if you are running a truck LS, there is no rear camshaft sensor trigger so you will need to upgrade to a front sensor if your engine has a rear cam sensor, so that means a new front cover and sensor as well as camshaft timing gear. ...read more
