LS1 Build: STAGE 1: Phase 2 ‘Cam/Pulley Install’
Okay folks here I am with week 2 update.. I plan on updating every Sunday…
STAGE 1: Phase 2 ‘Cam/Pulley Install’
Lets start this off with the Beer of the week.. We have here folks ‘Mississippi Mud’ Its a Black & Tan beer which has a little kick to it.. I also love the bottle it comes in, makes me feel like I should be sitting on a porch throwing meat to alligators..lol
Okay what I am installing today is a MS4 Cam from Texas Speed Shop and a ASP Harmonic Balancer. Now I bought the the Texas Speed Shop Camshaft package that comes with a Texas Speed Hardened Chromoly Pushrods and Dual Valve Sprigs.. I will install those later..
[B]MS4 CamShaft Package = $699.99
[B]ASP Harmonic Balancer = $214.99
Okay lets get started on removing the old stuff. First on the list is the balancer. You will need a 1″ socket to remove the bolt that holds it in place..
A braker bar is a must when it comes to taking off this damn bolt..
Again Advance Auto Parts come in handing when I needed to rent a tool.. I went there to pick up a Pulley puller. This tool is a must and really the only way you can actually get this dang pulley off the engine.
Tool set up…
The claw hooks grab the pulley and pulls it away from the engine.. As you begin to tightening the bolt it starts to get harder and harder to do.
That is when a pole comes in handy…lol
You know you are doing it right when you start to see silver from behind the pulley.
Just to give you an idea of the size difference between the ASP pulley and OEM pulley.. ASP gives you around a 15% more power, every bet counts..
Next we can remove the timing chain cover.. This requires you to use a 10mm,, really easy..
Bam!!, look at the LS6 oil pump and LS2 timing chain… Good stuff..
Now we can remove the timing chain sprocket, Unbolt the 3 cam gear bolts and remove the gear, letting the chain droop down into the oil pan for now
Next is the retainer plate
Next you’ll see a black/brown cam retainer plate behind the gear, held on by 4 10mm bolts. Unbolt and remove this too.
remove, the bolts..
Out with the old cam….
And in with the new.. The MS4 cam is a 239/242 .649″/.609″ Camshaft…. Oh yeah…
Now it is time to prep the new cam for install. Coat the whole thing with fresh motor oil, and transfer your 3 camgear bolts (or waterpump bolts if you were using those) to the end of the new cam so again you have a handle to grip onto.
Now take your time installing the new cam, and keep on coating the cam with fresh oil as you go..
Almost done,, the 3 camgear bolts come in handy towards the end when you don’t have nothing to grab onto,, so def do this..
Once in, re-install the cam retainer plate and its 4 10mm bolts. I usually put some locktite on the 4 bolts and the GM torque spec on them is 18lbft.
Then install the timing gear, and torque spec on these is 18lbft as well.
Now since the timing chain cover was off, I decided to spice it up some.. So I painted it a black crinkle. I think it turned out great.
Now for the time being I used the OEM balancer bolt to install the new ASP balancer. Now the Crankshaft Balancer Bolt (Installation Pass-to Ensure the Balancer is Completely Installed) needs to be torqued to 240lbft. And then remove bolt and replace with an ARP balancer bolt and torque to 37lbft. I will do this later once tranny is installed.
Well hope you enjoyed this weeks post…
Total spent: $2,464.98
