Sbc roller rockers

What do you guys run for roller rockers? Are the scorpions any good? How about the summit brand rockers? I’m looking for 7/16 1.6 rockers. Thank you.

Re: Sbc roller rockers

I have some ancient Crower aluminum roller rockers on mine. They've never let me down.

Pricey but probably the best stud mounted roller rocker avaible.

Re: Sbc roller rockers

With the aftermarket heads the distance between the stud and the valve is shorter. With most cams around .600"lift, std rockers designed for OEM type heads with stock length valves won't give good geometry. We have a USA made rocker that we have corrected the geometry on. These much like our BBC rocker that comes in 2 different geometric configurations. They give the best geometry and won't ware out valve guides quickly.
Wolfplace and Schwany like this.

Why is it we never have time or money to do it the right way in the beginning but we always have time and money to do it over again?

Gotta be 10+ yrs now and just checked lash/inspection, new gaskets etc, before we put the 406 in his truck and all was perfect.

Would anyone run the crane energizer rocker? Or are they not good quality?

Re: Sbc roller rockers

I have a set of those that came with a bunch of parts I bought. https://cranecams.com/rocker-arms/energizer-aluminum/ I thought when I was looking over what I got.....They looked a little inexpensive(I'm Being Kind Here). Some might say if one wanted to impress friends that you had "Roller Rockers", you could pull the Oil Fill Cap and see them....if you get my drift.

Ideas are like children: there are none so wonderful as your own.

I've had no issues with them either but I do not run my engine hard or race it. It's just a weekend cruise vehicle.
