Q:

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

A:

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

Q:

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

A:

This cam works great in a boosted 4.8.

Another great product from a trusted company,Chevy.This cam makes a great turbo or S/C cam.It will even work NA.Chevy uses it in both apps.There are more powerful cams available ,but not at a reasonable price.Iam a 35 year ASE Master Tech and I only use Chevy Performance parts..Great price,fast shipping,easy returns if needed.

one of the best stealth cams in the market. I installed it in my 2009 G8 with PAC springs and DOD delete kit. It will work with both N/A and Forced Induction Applications. keep up the good work :)

Great Piece for the money

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
