I am going to get the D-1SC for my 2001 WS6. Is it a good idea to spend the extra money on roller rockers, titanium retainers, pushrods and springs?
Or can I get away with the stock valvetrain?

Is this is big added expense?

Thx

If you are changing the cam yes. But the stock rockers should be fine either way.

I would. But only if I am adding the cam at the same time.

I agree with the guys... Only if you are adding a cam. Turbo cars usually need to upgrade because back pressure put more pressure on the exhaust valve springs, but with a SC there is no such pressure.

I will see what Bob has to say about this, maybe I won't have to add that stuff then. I know I will have to upgrade the stock clutch tho! I am thinking Textralia???? Seems like it gets the best reviews.

I WOULD PUT SPRINGS AND PUSHRODS IN IT ATLEAST. YOU GOT PRESSURE ON THE VALVES NOW, AND A BETTER STIFFER SPRING WILL KEEP THEM OPENING AND CLOSING AT A CONSISTENT RATE. CAM WOULD HELP TO. 216/224 ON 114 .551 TO .576 LIFT WITH 3* advance would go awesome to.

I'm still running stock pushrods

I would at least throw a set of 02+ LS6 spings in there to be safe, matter of fact I have a brand new set never even taken out of the package for 35.00 shipped if you want them

A set of comp 918 springs for $150 and a set of $80 pushrods. THat is all you need to upgrade the valvetrain for what you want to do. At minimum, do the springs. But the pushrods are right there, so might as well. The rest isnt needed.

We've done dozens of ProCharger installs using stock springs and pushrods. However, we did once have a local ProCharged T/A that we had previously installed the ProCharger on, that kept having a misfire. We swapped coils, etc, etc, turned out the valvesprings were totally shot at 35,000 miles! Now this customer was always beating the crap out of his car, always on the rev limiter, missed third and put it accidentally into first before, etc.
So valvesprings can and do go bad, it's certainly not a bad idea to change them when doing the ProCharger install. Bob

Does it take a lot of work to change the pushrods/springs???? Just looking at added labour costs. The stock rockers are ok????

Pushrods are easy. Stock rockers should be find. I am still running my stockers.

We charge $140.00 to replace valvesprings and pushrods. The factory rockers are some of the better ones on the market. Bob

The stock stuff is OK as long as you keep the rpms down. Once you get above 6k, they are not enough IMO. But the cam change would as others said require springs. The rockers are ok, but have been know to fall apart under toruture. But then so do some of the after market rockers. I've had very good luck with my Comp Pro Magnums.

It's all a matter of how hard you plan to push it. If in doubt, listen to Bob.....
