Stock pushrods will not suffice. You will need hardened pushrods.

Stock rockers will suffice, but upgrading them with a Comp Cam or Harland Sharp trunnion kit is a popular mod.

Most folks also upgrade the timing chain with addition of stiffer valve springs. An LS2 is the economical route. (I like the IWIS chain from Thunder Racing). Use new gears with the new chain.

Also consider new LS7 lifters and LS2 lifter trays.

 

Thanks. I was considering the LS2 chain, and this just helped me confirm that, so i will pull the trigger. As for length of pushrods, will stock length work?

 

You've got different heads and a cam that likely has a different base circle than stock. The smart thing to do is to get an adjustable-measurement pushrod and measure the right length. The way to do that is descirbed in the following post:

Most will agree with the LS2 chain. I prefer the Katech C5R chain which is what is sitting in my garage ready to replace the *relatively* sloppy LS2 chain.

As far as rockers go, the stock ones are fine with the upgraded trunnion but what lobes are you going to run on this cam?

As mentioned, new lifters are a good idea with the new cam and depending on the lobes, the LS7 lifters are probably perfect. The duration doesn't seem too crazy so I would imagine you are going with relatively mild lobes so LS7 lifters should be fine.

 

I don't know anything about types of lobes so i don't know which ones to use. Like i said, i'm still new to cam tech.

And i take it that with the suggestion of new lifters that the stock ls1 ones won't cut it? Or just that LS7's would hold up better/longer?

 

The LS7 lifters are the OE replacements for the LS1 lifters. You cannot buy LS1 lifters anymore unless you found someone with old stock. As far as lobes go, the faster ramp rate will decide on the lifters.

You may be unfamiliar with lobes, but I am sure you know about the relationship between force, time, and impact. The higher the ramp rate, the faster that lifter is going to come up in a short period time which means a greater force is applied to the lifter and impact is force over time. So, if you pick a more aggressive lobe, the lifter will experience a greater impact with each revolution of the camshaft which also means you will need a strong spring to help control inertia and keep everything in contact and under control.

I can't help you pick lobes, but I can tell you the lobes on my MS4 camshaft are not friendly to the LS7 lifters, haha. I *believe* the MS4 uses LSK lobes for the intake.

 

I gotcha. I would aim for less aggressive lobes in the interest of keeping my valvetrain healthy. I don't want to be changing springs every year haha. I have emailed COMP Cams, Thunder Racing, and TSP for suggestions about the cam. When i get a reply, i will ask about lobes.
