Pushrod/Rocker Arm Dilema
Pushrod/Rocker Arm Dilema I'll be getting an MS4 soon and have been reading about stress on the drivetrain. To free up some of the stress I was thinking about roller rockers. I want to use the stock ratio as I have heard 1.8's are not good but even with the stock ratio you need different sized pushrods depending on the rocker. The roller rockers come in sets so can anyone suggest roller rockers that I can use 7.4 Prods along with this cam??

I did see a post about Scorpions when I was searching. I am trying to find them in the 1.7 but of the places I do have them for sale don't appear to have that size.???

It is not the rockers you should change but the lifters. You should use Either Morrel or Cadillac Racing lifters.
The stock rockers are fine.
Also make sure you get springs that can handle that cam's seat and open pressures.

Yes if you want to control the LSK intake lobe. The other regular "Gold" will work but for how long?
They do not have enough open pressure to handle that lobe profile and lift.
I've seen a couple of posts about them breaking after only 10K miles and 12K miles.
