Which rockers for a boost application (15-25psi or more)
Which rockers for a boost application (15-25psi or more) I'm building a 364 boost motor and going with PRC LS3 aftermarket casting heads. The plans are to run this motor with 15-25psi of boost, maybe more. The goal is to make a 32-3300lb race weight car go into the 8 second zone. My question is a simple one. I am trying to figure out which rocker arm system to run. I know the stock rockers with the trunion upgrade are being used widely but are they something you would use on a motor that I will be making this much power with. Should I go Comp pro mag or just go all the way and get the Comp shaft system? If it doesn't need it I would not rather spend the money but if thats what I have to use then so be it. Thoughts? Thanks guys.

I'm big on the Jesel SS rockers for the ls. I'm sure they may not be the best or lowest priced. But I built a engine for a car with these rockers. This was about 6yrs ago. The car has made 630+rw since. And 1000s of dd,track and road trip miles. My dd 500rw n/a engine also has these rockers, I sold this motor, but still in use today.It sees 7000+rpm shift points often.
Also have another set for my own turbo engine project. Since also plan on up to 7000+rpm shifts. And I know these rockers won't spill there bearings.
For me it's either Jesel or stockers
