Scorpion rockers
 

My motors are about ready to be topped off. Heads are at machine shop. A while back I bought some scorpion roller rockers. What is everyone's thoughts on these? Who's running them problem free? Who's had/seen them break?

Thanks guys

Never owned them.

That said, you asked for thoughts, so here goes.....

Thinking they are no better or worse than any other domestically made aluminum rockers and that setup is going to make or break your experience with them.

Agreed there. What are your thoughts or experiences with domestically made aluminum rockers?

I've owned/ installed / ran aluminum arms by crane and by ford SVO. Never had a problem, but the cams were mild (230/ 230 .600 ish)

I'm going to be runnin 243/251 627/632

I have a set on my engine. Spring tension 150 on the seat 440 open. No problem yet. If you have after market heads you may need adjustable guide plates to center them.

You'll probably get quite a range of opinions, but I believe if you stay away from Chinese junk (scorpions are domestic and generally get good reviews) and set them up properly, they will be fine for what you're doing.

We're not talking about 8000 rpm and tons of lift and spring pressure here.

I have a set. 300 hrs. Trouble free. Nothing radical with my setup though. Spring tension 140/420

Thanks for the opinions. Keep em coming. Anyone with scorpion failures? If so what was set up?

50 hours on ours. 500efi setup. No issues. Knock on wood.

We went with the marine model. They chamfer the edges to clear the heads. Kinda nice. In talking to Teague, madara, etc. everyone recommended scorpion. They seem to have replaced crane gold series. Atleast that's how I see it...
