I can get these pretty cheap, they list for $429 on Crane's site. They are non-self aligning narrow body, 1.6 ratio, 3/8 studs. I am only asking this b/c the "big name" online stores like thunderracing don't list them. Thanks!

Edit: Now I'm really confused. Click here to see the description It says its for a 3/8 stud, but I thought all Crane's NSA rockers were for 7/16 studs? Would it be ok to use a 3/8 stud with a cc306 spinning close to 7000 rpm?

 

I am running them with my bolt-on set up and will reuse them in my 383 project. All of the narrow bodys are for 3/8 stud. The standard SB and BB Chevy comes in 7/16. You can run them to 7000 no problem. Summit and Jegs sells them for $300.

 

i'm using them with an ex 224 230. no clearance problems under stock valve covers
